A plank in a bog is not just an old piece of wood. Its shape, position and relationship to the surrounding peat can help an archaeologist ask who made it, when it was placed there and what people were trying to do. This guide teaches 100 English bog archaeology vocabulary words, with meanings, natural collocations and original examples.
Ireland offers a particularly vivid setting. At Corlea in County Longford, an Iron Age timber roadway survives beneath and within the story of the peatland. Learning to describe a trackway, a sample or a date gives you useful language for museum visits, historical reading and evidence-based writing. The question is often delightfully small: what does this particular piece actually tell us?
Choose a ten-word chapter, cover the meanings and explain a find in two sentences. “Top 100” is a curated learning selection, not a statistical frequency ranking. Most terms are international archaeological English; the examples and classroom records are invented unless a named source is explicitly cited. This is a language guide, not an invitation to excavate or collect objects.

Start with a small independent check
Read this fictional museum caption: “An oak plank came from a trackway. A tree-ring study dated the timber. Therefore, we know the name of the person who crossed it.” The first two statements concern material and dating; the third needs a quite different kind of evidence. If the jump feels obvious, explain exactly what is missing.
If peat, waterlogged and artefact are unfamiliar, begin with chapters 1–2. If you recognise objects but confuse a sample’s age with every event at a site, start at chapter 5. If you understand a report but write a more certain conclusion than its author, begin with chapters 8–10. A useful diagnostic finds the first broken connection rather than awarding a label such as “bad at history”.
Draw three boxes: object, surrounding deposit, interpretation. Put one observation in each of the first two and a possible explanation in the third. Now change the object’s recorded position. Would the explanation still hold? This little exercise makes context visible before the specialist vocabulary arrives.

CHAPTER 1 OF 10
1. The landscape that holds the evidence
Begin with the material around the object. Wetness, layers and preservation describe different features; one adjective cannot do all three jobs.
| No. | Word or phrase | Meaning and usage | Useful collocation | Original example |
|---|---|---|---|---|
| 1 | peat | Partly decomposed plant material accumulated in wet conditions. | a layer of peat | The drawing places the timber beneath a layer of peat. |
| 2 | bog | A peatland supplied mainly by precipitation; not every wetland is a bog. | a raised bog | The class compared the raised bog with the river margin. |
| 3 | waterlogged | Filled or saturated with water. | waterlogged timber | The caption describes waterlogged timber without calling it strong. |
| 4 | anoxic | Without oxygen; a technical environmental adjective. | anoxic conditions | The student linked anoxic conditions with the survival of some organic material. |
| 5 | organic | Derived from living organisms; here not a farming certification. | organic remains | Wood and seeds were listed as organic remains in the exercise. |
| 6 | decomposition | The process by which material breaks down. | slow decomposition | The diagram contrasts plant growth with slow decomposition. |
| 7 | deposit | Material laid down or accumulated in a place. | a peat deposit | The report describes the deposit surrounding the wooden piece. |
| 8 | sediment | Particles deposited by water, wind or other processes. | a sediment sample | The learner kept the sediment sample separate from the object record. |
| 9 | stratum | One distinct layer; the plural is strata. | an underlying stratum | The section drawing shows an underlying stratum beneath the timber. |
| 10 | buried | Covered by soil, peat or another material. | a buried surface | The old walking surface is now buried in the fictional diagram. |
Usage check: organic remains refers to biological origin. It does not mean that someone grew the material under modern organic-farming standards.
CHAPTER 2 OF 10
2. Objects need records and relationships
A find becomes more informative when its location and relationships are recorded. These words help explain why documentation belongs with discovery.
| No. | Word or phrase | Meaning and usage | Useful collocation | Original example |
|---|---|---|---|---|
| 11 | archaeology | Study of past human life through material evidence. | wetland archaeology | Wetland archaeology connects fragile objects with their surroundings. |
| 12 | artefact | An object made or modified by people; artifact is another spelling. | a wooden artefact | The shaped peg was described as a wooden artefact. |
| 13 | findspot | The recorded place where an object was discovered. | the original findspot | The museum exercise asks why the original findspot matters. |
| 14 | context | An archaeological unit or the recorded relationships around a find. | archaeological context | The photograph alone did not preserve the object’s full archaeological context. |
| 15 | provenance | An object’s origin or history; not always its exact excavated position. | documented provenance | The label gave documented provenance but no detailed site plan. |
| 16 | assemblage | A group of finds considered together from a defined context. | an artefact assemblage | The class discussed the assemblage without assuming every object had one use. |
| 17 | feature | A recognisable archaeological element, often not removable as one object. | a structural feature | The line of posts was recorded as a structural feature. |
| 18 | survey | Systematic examination and recording of an area. | an archaeological survey | The survey map distinguished observed remains from unexamined ground. |
| 19 | excavation | Controlled investigation through removal and recording of deposits. | a recorded excavation | The account explained how excavation changed the evidence available. |
| 20 | documentation | Records describing observations, methods and decisions. | detailed documentation | Detailed documentation helped another researcher follow the interpretation. |
Contrast context with provenance: a broad origin can be known even when a precise excavated position has been lost. State which information you actually have.
CHAPTER 3 OF 10
3. Timber, construction and worked surfaces
Name the component before deciding its purpose. A plank, peg and stake can contribute to a structure without telling us every detail of its use.
| No. | Word or phrase | Meaning and usage | Useful collocation | Original example |
|---|---|---|---|---|
| 21 | trackway | A constructed route across terrain, sometimes made of timber. | a timber trackway | The exhibition drawing shows a timber trackway crossing wet ground. |
| 22 | togher | English loanword from Irish tóchar, used for a causeway or bog road. | a prehistoric togher | The reader learned togher alongside the more familiar word trackway. |
| 23 | plank | A relatively long, flat piece of sawn or split timber. | an oak plank | A wide oak plank lay above the supporting pieces. |
| 24 | beam | A substantial timber serving a structural role. | a supporting beam | The model’s supporting beam carried several smaller pieces. |
| 25 | peg | A small pin used to secure or position components. | a wooden peg | The illustration showed a wooden peg beside a joint. |
| 26 | stake | A pointed length of wood driven into the ground. | a sharpened stake | The student described the sharpened stake without guessing its owner’s name. |
| 27 | brushwood | Small branches and twigs considered together. | a brushwood layer | The section included a brushwood layer beneath the larger timbers. |
| 28 | joint | A place where separate components meet or connect. | a timber joint | The close-up helped the class describe the timber joint. |
| 29 | tool mark | A trace left by a tool on a surface. | visible tool marks | Visible tool marks supported the claim that the wood had been worked. |
| 30 | alignment | The arrangement of objects along a line or direction. | a parallel alignment | The plan showed a parallel alignment of several planks. |
Togher is a loanword, while tóchar is the Irish source form. Irish already uses the Latin alphabet, so no separate transliteration is required here.
CHAPTER 4 OF 10
4. Make position and shape readable
A drawing is an argument about relationships as well as a picture. Check its scale, reference point and orientation before drawing conclusions.
| No. | Word or phrase | Meaning and usage | Useful collocation | Original example |
|---|---|---|---|---|
| 31 | plan | A drawing showing a site or structure from above. | a measured plan | The measured plan revealed relationships hidden in the close-up photograph. |
| 32 | section | A drawing or exposure showing a vertical slice through deposits. | a section drawing | The section drawing showed which layer lay above the wood. |
| 33 | profile | The outline or vertical arrangement of a surface or sequence. | a peat profile | The learner labelled the peat profile from top to bottom. |
| 34 | grid | A network of reference lines used to locate observations. | a recording grid | Each point on the classroom map had a place in the recording grid. |
| 35 | coordinate | A value used with others to specify position. | recorded coordinates | The coordinates allowed the find to be located on the plan. |
| 36 | datum | A fixed reference used for measurements. | a survey datum | He measured the fictional levels from the same survey datum. |
| 37 | scale | The ratio between a representation and the real object. | a scale drawing | A scale drawing allowed the students to compare timber lengths. |
| 38 | orientation | The direction in which something lies or faces. | the structure’s orientation | The north arrow helped explain the structure’s orientation. |
| 39 | dimension | A measurable extent such as length, width or thickness. | record the dimensions | The description recorded dimensions before discussing possible function. |
| 40 | interval | The distance or time between points or events. | a regular interval | The stakes appeared at a regular interval in the model. |
Try describing a plan without pointing at it: “The stakes run parallel to the planks.” If a reader can sketch your relationship, the vocabulary is working.
CHAPTER 5 OF 10
5. Dates answer particular questions
A date belongs to a sample, method and interpretation. Establish what event the evidence can constrain before placing a neat year in a caption.
| No. | Word or phrase | Meaning and usage | Useful collocation | Original example |
|---|---|---|---|---|
| 41 | chronology | The ordering and dating of events. | a site chronology | The student built a site chronology from several kinds of evidence. |
| 42 | relative dating | Establishing whether something is earlier or later without a calendar date. | a relative dating sequence | Relative dating placed one deposit after another in the exercise. |
| 43 | radiocarbon dating | Estimating the age of suitable once-living material using carbon isotopes. | radiocarbon dating of wood | The label identified radiocarbon dating as the method used on the sample. |
| 44 | dendrochronology | Dating or studying wood through patterns of annual growth rings. | a dendrochronology study | The learner explained why a dendrochronology study needs comparable ring patterns. |
| 45 | growth ring | A layer of wood formed during a growth period, commonly a year. | annual growth rings | The enlarged photograph made the annual growth rings easier to distinguish. |
| 46 | felling | The cutting down of a tree. | a felling date | A timber date did not automatically establish a precise felling date. |
| 47 | calibration | Adjustment of measurements using a reference relationship. | radiocarbon calibration | The lesson separated radiocarbon calibration from simply counting years backwards. |
| 48 | date range | A span within which a date is estimated to fall. | an estimated date range | The caption retained the estimated date range instead of choosing its midpoint. |
| 49 | contemporary | Belonging to the same period in this historical sense. | contemporary activity | The writer asked whether the two finds represented contemporary activity. |
| 50 | sequence | An ordered succession of layers, actions or events. | a construction sequence | The construction sequence began with supports and then added the surface. |
Do not equate the age of surviving tree rings, the felling of a tree and the construction of a structure without supporting information.
CHAPTER 6 OF 10
6. Small remains and past environments
Environmental remains widen the question from what people made to the conditions around them. Each kind of evidence has its own limits.
| No. | Word or phrase | Meaning and usage | Useful collocation | Original example |
|---|---|---|---|---|
| 51 | pollen | Tiny grains produced by seed plants, sometimes preserved in deposits. | preserved pollen | Preserved pollen supplied clues for the imagined environmental study. |
| 52 | seed | A plant’s reproductive structure that may survive in archaeological deposits. | a charred seed | The exercise distinguished a charred seed from a modern seed in the bag. |
| 53 | charcoal | Carbon-rich material remaining after incomplete burning of wood or other plant matter. | a charcoal fragment | A charcoal fragment raised a question about burning rather than answering it alone. |
| 54 | macrofossil | A preserved biological remain large enough to examine without high magnification. | plant macrofossils | The study notes listed plant macrofossils separately from pollen. |
| 55 | microscope | An instrument that magnifies small objects or structures. | examine under a microscope | The student explained why some remains require a microscope. |
| 56 | sample | A selected portion taken for examination. | a labelled sample | The labelled sample could be connected to its recorded location. |
| 57 | sampling strategy | A planned approach to selecting material for analysis. | a consistent sampling strategy | The class discussed how the sampling strategy might miss some variation. |
| 58 | proxy | An indirect indicator used to investigate something not observed directly. | an environmental proxy | Pollen served as an environmental proxy in the explanation. |
| 59 | vegetation | The plant life covering an area. | past vegetation | The reconstruction of past vegetation included an explicit uncertainty. |
| 60 | reconstruction | An evidence-based representation of a past condition or structure. | a landscape reconstruction | The landscape reconstruction was labelled as an interpretation. |
A proxy supplies indirect evidence. Calling something a proxy should lead to the question “What relationship makes it informative?”
CHAPTER 7 OF 10
7. Care after discovery
Survival underground and stability after exposure are different matters. These terms describe professional care, not a home treatment recipe.
| No. | Word or phrase | Meaning and usage | Useful collocation | Original example |
|---|---|---|---|---|
| 61 | conservation | Professional investigation and care intended to safeguard heritage material. | wood conservation | The display explained that wood conservation continued after excavation. |
| 62 | preservation | Survival or protection of material against deterioration. | organic preservation | The worksheet asked which conditions supported organic preservation. |
| 63 | stabilisation | Measures intended to reduce harmful change or movement. | material stabilisation | The record distinguished stabilisation from replacing missing parts. |
| 64 | deterioration | A decline in physical condition. | surface deterioration | The conservator’s fictional notes described surface deterioration precisely. |
| 65 | shrinkage | Reduction in size, sometimes associated with moisture loss. | uneven shrinkage | The model comparison showed how uneven shrinkage could alter a shape. |
| 66 | distortion | A change from an earlier or intended shape. | structural distortion | The learner considered whether distortion affected the measured alignment. |
| 67 | fragile | Easily damaged or broken. | fragile material | The description treated the surviving wood as fragile material. |
| 68 | support | A structure or material that holds something securely. | a protective support | The exhibit drawing included a protective support beneath the object. |
| 69 | monitoring | Repeated observation or measurement to detect change. | condition monitoring | Condition monitoring produced a series of records rather than one photograph. |
| 70 | storage | Keeping material in an appropriate place and conditions. | controlled storage | The museum lesson connected controlled storage with long-term care. |
Preserved does not mean indestructible. Describe condition separately from age, appearance and the fact of survival.
CHAPTER 8 OF 10
8. Test the explanation
An interpretation should survive questions. Distinguish what was observed from what was inferred and ask what might change the conclusion.
| No. | Word or phrase | Meaning and usage | Useful collocation | Original example |
|---|---|---|---|---|
| 71 | observation | Something noticed or measured, distinguished from its explanation. | a recorded observation | The recorded observation concerned the mark’s shape, not its purpose. |
| 72 | inference | A conclusion drawn from evidence and reasoning. | a cautious inference | The arrangement supported a cautious inference about construction. |
| 73 | hypothesis | A proposed explanation that can be investigated. | an alternative hypothesis | The group proposed an alternative hypothesis for the timber alignment. |
| 74 | association | A recorded relationship between finds or features. | a spatial association | Spatial association did not by itself prove simultaneous use. |
| 75 | disturbance | A later change that disrupts an earlier arrangement. | later disturbance | Later disturbance complicated the reading of the layers. |
| 76 | intrusive | Introduced into an earlier deposit at a later time. | an intrusive object | The exercise asked whether the modern fragment was intrusive. |
| 77 | residual | Older material redeposited in a later context. | residual material | Residual material could be older than the deposit containing it. |
| 78 | corroborate | To provide additional support for a claim. | corroborate an interpretation | The second record helped corroborate the interpretation. |
| 79 | contradict | To conflict with a statement or explanation. | contradict a hypothesis | The new measurement appeared to contradict the original hypothesis. |
| 80 | uncertainty | The extent of what remains unresolved or imprecise. | acknowledge uncertainty | The final paragraph acknowledged uncertainty without dismissing all evidence. |
Possible and plausible are not synonyms for proved. Use them when the evidence supports consideration, not certainty.
CHAPTER 9 OF 10
9. Collections and public interpretation
Museums connect material with records and visitors. Clear labels make copies, original fragments and interpretive drawings easy to distinguish.
| No. | Word or phrase | Meaning and usage | Useful collocation | Original example |
|---|---|---|---|---|
| 81 | interpretation | An explanation of what evidence may mean. | a proposed interpretation | The panel separated the proposed interpretation from the object’s description. |
| 82 | caption | A brief explanation accompanying an image or object. | an informative caption | The informative caption identified both material and source. |
| 83 | replica | A later copy of an object. | a labelled replica | The labelled replica helped visitors imagine the complete shape. |
| 84 | original | The actual historical object, distinguished from a copy. | an original fragment | Only the original fragment was used for the material analysis. |
| 85 | display | An arrangement presented for people to view. | a museum display | The museum display included a diagram as well as an object. |
| 86 | curator | A professional responsible for developing and interpreting collections. | a museum curator | The fictional curator asked for a clearer explanation of the date. |
| 87 | collection | A group of objects maintained or studied together. | an archaeological collection | The archaeological collection included ordinary tools as well as rare objects. |
| 88 | accession | The formal addition of an object to a collection, or its identifying record. | an accession number | The accession number linked the display item to its records. |
| 89 | archive | A preserved body of records or the place that holds them. | an excavation archive | The writer checked the excavation archive before summarising the method. |
| 90 | heritage | Material and non-material inheritances valued by communities. | archaeological heritage | The discussion treated archaeological heritage as a shared responsibility. |
A replica can be excellent teaching material. The problem is not copying; it is failing to tell the reader what they are looking at.
CHAPTER 10 OF 10
10. Write with the right degree of certainty
Precise verbs can keep a historical account honest. The final ten words help you state a useful conclusion without pretending uncertainty has vanished.
| No. | Word or phrase | Meaning and usage | Useful collocation | Original example |
|---|---|---|---|---|
| 91 | evidence | Information or material used to support an explanation. | material evidence | The paragraph connected each claim to material evidence. |
| 92 | claim | A statement whose support can be examined. | a historical claim | The historical claim was more specific than the supplied record allowed. |
| 93 | qualify | To limit or refine a statement so it is more accurate. | qualify a conclusion | The student qualified the conclusion after noticing the missing location. |
| 94 | plausible | Reasonable or possible, but not thereby proved. | a plausible explanation | The plausible explanation still needed further support. |
| 95 | tentative | Provisional and open to revision. | a tentative identification | The catalogue retained a tentative identification of the wooden piece. |
| 96 | documented | Supported by an identifiable record. | a documented discovery | The account distinguished a documented discovery from a local story. |
| 97 | undated | Without an established date. | an undated feature | The undated feature could not anchor the chronology. |
| 98 | comparison | Examination of similarities and differences. | a controlled comparison | The comparison used objects with clearly stated differences. |
| 99 | revise | To change an account in response to review or new evidence. | revise an interpretation | The group revised its interpretation when the context changed. |
| 100 | synthesis | An account that brings several sources or observations together. | an evidence-based synthesis | The final synthesis kept disagreement visible instead of smoothing it away. |
Evidence is normally uncountable in this usage: say “a piece of evidence” or “several lines of evidence”, not “an evidence”.
A museum label that earns its conclusion
Imagine an invented classroom collection consisting of a photograph, a plan and a short record. The photograph shows three shaped wooden planks. The plan places them side by side above narrow supporting timbers. The record says that a wood sample was analysed, but it gives no result. None of these materials comes from an actual excavation.
A first draft reads: “The ancient bridge carried royal chariots in 148 BC.” It sounds wonderfully decisive. It also quietly invents a date, a function, a kind of vehicle and the identity of its users. Specific vocabulary is only helpful when its specificity is earned.
Start with visible evidence: “Three shaped planks lie above supporting timbers.” Next, introduce an interpretation with its basis: “Their arrangement is consistent with a constructed walking surface.” Finally, mark the limit: “The supplied record does not establish its date or identify its users.” The revised label is less theatrical and considerably more useful.
In an illustrative dialogue, a learner asks, “Can I call it a trackway?” A partner replies, “You can describe it as a possible trackway, then explain the arrangement that supports your interpretation.” The first learner asks, “Does possible mean we know nothing?” “No. It tells the reader which part is an inference.”
Now add a second invented record: one plank had been moved before recording. The caption needs another revision because the original arrangement is less secure. Write “The surviving record suggests a constructed surface, although one plank’s original position is uncertain.” Do not erase the evidence that remains; reduce only the part of the claim affected by the new information.
For a stronger paragraph, connect rather than stack the terms: “The disturbed context limits interpretation because the recorded alignment may not reproduce the original structure.” Context, alignment and interpretation now do jobs in a sentence. That is the difference between knowing a list and using it.
Ireland’s peatlands preserve more than one kind of history
The Office of Public Works account of Corlea describes an oak-plank roadway built in 148 BC and an 18-metre section displayed in a specially designed hall. Its suggestion of a ceremonial connection is presented as a possibility. Keep that distinction when retelling the story: a documented structure and a proposed purpose do not have identical evidential status.
The Heritage Council’s Peatland Archaeology explains why waterlogged, oxygen-poor conditions can preserve fragile organic remains. It also places timber structures among a wider variety of archaeological evidence. Preservation is selective, not a promise that everything buried survives equally well.
Think about the distinction between natural wood and worked wood. A buried tree can inform environmental history without being a human-made artefact. Tool marks, deliberate arrangement and associated evidence may support a different interpretation. The English word ancient does not settle that question; it supplies an impression of age, not an explanation of origin.
Bog archaeology and ecological restoration can meet on the same landscape, but they answer different questions. An archaeologist may investigate a timber structure’s construction and context; an ecologist may investigate water levels and peat-forming vegetation. The existing Irish raised bog restoration vocabulary guide provides the environmental route when that is the question you want to pursue.
Ireland’s archaeological record also includes towns, coasts, farmland and buildings. A peatland lesson should not turn the whole country into one misty backdrop. Nor should old objects be used to assign a single identity to every community that has lived on the island. Say which place, period and source your statement concerns.
The learning connection is practical. English Tuition | Ireland emphasises independent interpretation and writing for a defined purpose. A museum caption, an evidence paragraph and a visitor’s question give this vocabulary three different audiences. The linked education guide concerns the Republic of Ireland; its school information should not be transferred to Northern Ireland or Singapore.
Practise, retrieve and check
Try these questions without the word tables. Explain your reason before opening an answer; a correct choice made by guessing is a useful beginning, but it is not yet reliable control.
1. Which is an artefact: an unworked branch or a deliberately shaped wooden peg?
Check your reasoning
The shaped peg is an artefact because people made or modified it. The branch can still be valuable environmental evidence; usefulness does not make it an artefact.
2. A plank is waterlogged. Does that mean it is structurally strong?
Check your reasoning
No. Waterlogged describes its water-filled condition. A preserved shape may be fragile, so condition and strength require their own assessment.
3. Choose the clearer phrase: conduct a date or date a timber sample.
Check your reasoning
Date a timber sample. You can also conduct a dating analysis. The verb date and the noun dating need different sentence structures.
4. A sample’s outer rings are missing. Can you automatically identify the felling year?
Check your reasoning
No. Missing outer rings limit the relationship between the dated surviving wood and the tree’s felling. A precise-looking number must retain the method’s qualifications.
5. Rewrite: The objects prove that everybody used this route.
Check your reasoning
The objects may support an interpretation of route use, but they do not identify every user. A stronger answer would specify what objects, where they were recorded and what activity they support.
6. Why record a find’s position before interpreting it?
Check your reasoning
Position and relationships help establish context. Without them, two objects may appear associated even if they entered the deposit at different times.
7. Does a replica become an original when it is historically accurate?
Check your reasoning
No. Replica describes a later copy. Accuracy concerns how faithfully it represents something; it does not change its identity.
8. Write a caption with observation, inference and limit.
Check your reasoning
One possible answer: “The photograph shows parallel shaped timbers. They may form a constructed surface. The photograph alone does not establish the date or intended users.” Other answers work if all three functions remain clear.
From ten recalled words to a defensible explanation
Begin with five concrete terms and five relationship terms: plank, peg, peat, sample, trackway; context, sequence, association, inference, uncertainty. Cover the list and explain how the first five might supply evidence for the second five. If you cannot connect them, reduce the task to one object and one question.
For speaking, give a one-minute account of an invented museum display. Your partner may interrupt once with “How do you know?” Answer with the source of the claim, not a louder repetition. A photograph, a laboratory result and a curator’s interpretation provide different kinds of support.
For writing, produce a 100-word label for a younger reader. Use no more than six specialist terms and explain each through the sentence around it. Then write a short paragraph for an older student that adds one limitation. Audience changes the amount of explanation, not the facts you are entitled to invent.
Parents can listen for the difference between “I saw” and “I think”. Ask the learner to point to the supplied evidence before correcting every spelling. Teachers can change one detail—an uncertain findspot, a missing sample label, a disturbed layer—and ask which sentence must change. This diagnoses reasoning more precisely than another copied definition.
Return after a day and then after several days. Retrieve words from a picture or a question rather than from their printed order. Mix in a pottery fragment or a building photograph so the learner must decide which bog-specific terms still apply. Successful transfer includes recognising when a word is unsuitable.
If the learner can recall meanings but cannot organise an explanation, use the eduKate vocabulary learning hub to work on collocations, retrieval and use in fresh contexts. If the obstacle is interpreting a source, return to the worked caption. The next lesson should repair the observed difficulty.
Frequently asked questions
Are these Irish-language vocabulary words?
Mostly no. They are English archaeological terms used through Irish examples. Togher is labelled as an English loanword from Irish; the guide does not pretend to be a full Irish-language course.
Does Top 100 mean the most frequent words in excavation reports?
No. The selection is editorial and organised for learning. No measured corpus ranking or search-volume claim is being made.
Is every preserved object from a bog prehistoric?
No. The environment does not establish a date. Dating depends on evidence and method, and peatlands can contain material from different periods.
Is preservation the same as conservation?
Preservation describes survival or protection from deterioration; conservation includes professional investigation and care. An object that survived underground may still need specialist conservation after exposure.
Must I memorise all 100 words before visiting a museum?
No. Start with object, material, context, date and interpretation. Ten usable words and a thoughtful question are a better first target than a hurried recital.
Can these words help with school English?
Yes, especially with precise description, source interpretation and cautious conclusions. They are enrichment vocabulary, not an official examination list or a substitute for the learner’s actual syllabus.
