Using this bank
Make a technical passage usable: identify the thing, the measurement and the condition before drawing a conclusion.
The complete list is above. Go to age guidance, the practical method, definitions and examples, common problems, frequent questions or all published age banks.
A specification sheet, a laboratory diagram and an environmental report can all become difficult for the same reason: one unfamiliar term hides the relationship you need to understand. You may recognise most of the sentence while being unsure what is measured, what changes or what the conclusion actually covers. This bank helps you find that missing piece.
Begin with the task in front of you. You might be comparing two descriptions, following a documentary, preparing a question for a lecturer or making sense of a workplace explanation. Choose the word that blocks that task. Looking up every unfamiliar expression is usually unnecessary for answering the immediate question.
The first sixteen volumes already contain 32,000 distinct listed entries. This continuation therefore includes substantial specialist vocabulary. Its advanced section is an optional reference shelf; it is not a list every eighteen-year-old should recognise. Start anywhere useful, and return to a simpler explanation whenever the subject needs more groundwork.
What Age 18 means here
How People Learn II, from the National Academies of Sciences, Engineering, and Medicine, describes how existing knowledge affects the organisation and interpretation of new information. It also reviews ways to support learning, including retrieval practice. Connecting a term with a process you can explain is a useful aim; memorising its spelling alone leaves much of the reading task unfinished. National Academies: How People Learn II — Knowledge and Reasoning.
Age 18 identifies this Teen/Young Adult volume. The three bands organise relative difficulty within this bank. They are editorial labels, not developmental scores, qualification requirements or a timetable for adulthood. A beginner entry can still be unfamiliar, and an advanced entry can be familiar within your particular interest.
| Band | What it means here | How to choose |
|---|---|---|
| Beginner | A starting route within this collection | Choose an entry that fits something you already notice, discuss or enjoy. |
| Intermediate | More detail, description and relationships | Choose a word that makes an existing idea more precise or adds a useful distinction. |
| Advanced | Optional specialist reading extension | Use a term only when a suitable text, interest or question gives it a meaningful context. |

Follow the term from the sentence to a checkable explanation
1. Write the question first
Name the information you need: what a part does, what a number represents or why a conclusion follows. Keep the question small enough that one paragraph could answer it. This gives you a reason to choose one word and a way to decide when the lookup has helped.
2. Separate the name from the claim
A term may identify a material, a structure, a process or a unit. A claim says something about that thing. Knowing what a turbopump is does not establish how efficiently a particular pump operates. Underline the claim and keep it separate from the label.
3. Check the meaning in this subject
Use the source glossary, an appropriate professional organisation or a reliable specialist reference. Read enough of the entry to identify the intended sense. For a diagram, match the term to the labelled feature. If the explanation contains another essential unknown, resolve that smaller gap before continuing.
4. Keep units and conditions beside the number
Record what was measured, the unit, the relevant setting and any stated uncertainty. Compare like with like. A number taken under one operating condition may not answer a question about another condition. If the source omits something necessary, turn the omission into a precise question.
5. Explain, check, then revisit
Close the definition and explain the term in one ordinary sentence. Reopen the source to correct your account. Later, try the term with a second example or sketch. This is a suggested reading routine, not a tested programme or a promise that a particular number of repetitions will produce mastery.
The National Academies review discusses retrieval practice and the importance of prior knowledge and context. Those principles support checking what you can explain and revisiting useful material. They do not validate these 2,000 entries, their age label or the exact routine suggested here. National Academies: How People Learn II — Knowledge and Reasoning.

Useful meanings and examples from ordinary life
Examples use familiar words from across the series, including earlier volumes. The no-repeat rule applies only to the numbered bank entries. The short meanings below explain the intended sense in each example; they are not exhaustive dictionary entries.
1. Following an airflow drawing
plenum — an enclosed chamber forming part of an air-distribution system, connected to one or more ducts
“The arrows show air passing from the plenum into several ducts.”
Locate the chamber and the connecting ducts. The label identifies a component; the drawing alone does not establish how well the complete system performs.
Meaning reference: US EPA: Introduction to Indoor Air Quality — Section 8.2, Useful Definitions, plenum.
2. Identifying the added solution
titrant — the solution containing the reacting substance added during a titration
“The diagram labels the solution being added as the titrant.”
Separate the solution being added from the sample being analysed. This is a reading example; an actual procedure requires its own instructions, supervision and appropriate equipment.
Meaning reference: IUPAC Gold Book: titrant.
3. Comparing a component value
picofarad — one trillionth of a farad, a unit of capacitance
“The stated capacitance is 1,000 picofarads, equal to one nanofarad.”
Convert both quantities to the same unit before comparing them. The conversion changes how the value is written; it does not establish the precision of the component or measurement.
Meaning reference: BIPM: SI prefixes.
4. Interpreting a bright microscope image
autofluorescence — light emitted after excitation by naturally fluorescent components already present in a specimen
“The caption identifies some of the background signal as autofluorescence.”
Check whether the bright region comes from a naturally fluorescent component or an added label. Brightness alone is not enough to identify a particular structure or molecule.
Meaning reference: Nikon MicroscopyU: autofluorescence.
5. Reading a biological explanation
epigenome — the collection of chemical modifications to DNA and associated proteins that influences how genetic information is used
“The article compares epigenome patterns in two cell types.”
Keep changes to these marks separate from changes to the DNA sequence. The word does not, by itself, establish why a difference arose or what it means for a whole person.
Meaning reference: NHGRI: Epigenomics Fact Sheet.
6. Describing a climbing plant
thigmotropism — a directional growth response to contact or touch
“The tendril curves towards the support after making contact, illustrating thigmotropism.”
Notice that the example concerns the direction of growth. Do not assume every rapid movement following touch is the same kind of response.
Meaning reference: Penn State Extension: How Do Plants Move?.
7. Reading the texture of a metamorphic rock
porphyroblast — a mineral crystal that grew during metamorphism and is noticeably larger than much of the surrounding material
“The image labels the large garnet crystal as a porphyroblast.”
The label connects size with a geological growth history. It does not tell you the crystal’s age simply from its appearance, and a large crystal in another setting may require a different term.
Meaning reference: British Geological Survey: geological glossary.
8. Following energy through a machine
turbopump — a pump driven by a turbine
“The diagram connects the turbine and pump through a shaft.”
Trace what drives the pump and what fluid the pump moves. Keep those functions distinct before trying to interpret efficiency, pressure or performance claims.
Meaning reference: NASA: Internal flows in a rocket-engine turbopump.
Build a short explanation with an honest boundary
A useful note has five parts: the term, its meaning in this passage, the example, the evidence and the remaining question. For a component value, the evidence might be a labelled specification. For a biological claim, it might be a comparison reported in a study. Naming the source helps you return to the original context when your understanding changes.
Consider this invented reading example: two documents give a pump’s flow rate, but one describes a different operating pressure. You can understand both numbers and still lack a fair comparison. Write the condition beside each value before deciding what the figures show. The vocabulary has helped when it reveals the missing comparison, even if it does not supply the missing data.
Keep recognition and explanation separate. You may recognise epigenome on sight while still needing a diagram to explain its relation to DNA. You may explain a picofarad correctly while needing help with the circuit around it. Record the part you understand and the part you need to investigate. That makes your next question more useful than a general statement that the whole topic is confusing.
When you return to a term, change the example. Explain a second diagram, compare two captions or describe the idea to a friend who has not read the source. If your explanation becomes vague, consult the reference and adjust the note. The point is to improve the connection between the word and the situation, rather than to make a definition sound impressive.

Five possible occasions to return to a useful word
Choose occasions that fit naturally. These are not five compulsory days, and there is no daily quota or completion deadline. Repeat, change or stop an activity according to your interest and purpose.
| Occasion | What to try |
|---|---|
| Before reading a technical document | Choose one question and identify where the document is likely to answer it: a diagram, a methods section, a table or a specification. |
| When a number seems surprising | Check the unit, scale, stated conditions and whether the figure is measured, estimated or calculated. Record what remains unclear. |
| When a diagram has many labels | Follow one pathway or relationship first. Use the key and caption to decide which labels matter to that pathway. |
| When discussing the passage | Give a plain explanation, name the source and distinguish what it shows from what you are inferring. Invite a question about the connection. |
| At the next useful encounter | Try to explain the term before opening your note. Compare the new context with the earlier one, then correct or extend the note if needed. |
Reading across subjects and languages
Let the topic guide your reading. A story, information book, picture, recipe, sign or instruction can give a word a useful context. Read with someone when you want support, or discuss an unfamiliar passage afterwards. Pause for a necessary explanation and return to the meaning of the passage.
If you use more than one language, add a translation or a familiar explanation to your own notes when that helps. Check it against the particular sentence: one English word may need different translations in different settings. This English bank is a reference you can adapt, not a measure of everything you know.
When something is not working
| What you notice | A useful adjustment |
|---|---|
| The dictionary explanation is harder than the original sentence | Try a subject introduction with a labelled example. Identify the smallest missing idea instead of opening an endless chain of definitions. |
| Two sources appear to disagree | Compare the intended meaning, field, conditions and date. A broad introduction and a specialised standard may draw their boundaries differently. |
| You can name the parts but cannot describe the process | Follow one change through the diagram: what enters, what happens and what leaves. Ask which connection you still cannot explain. |
| You want to apply a term to a practical decision | Return to the actual instructions, specifications or qualified advice relevant to that decision. A vocabulary definition does not replace the information needed to operate equipment or interpret a personal result. |
| The bank feels too specialised | Choose an earlier volume or a topic you already enjoy. Useful vocabulary grows from repeated meaningful encounters, and this collection has no compulsory reading order. |

Frequently asked questions
Should an eighteen-year-old learn every word here?
No. Use the bank as a reference for current reading, interests and questions. Many entries belong to specialist fields. The age label identifies a volume in the series; it does not establish what you should know before studying, working or living independently.
Does beginner mean the word is easy for everyone?
No. It marks a more approachable route within this particular bank. Familiarity depends on experience. A workshop term may be familiar to someone who repairs equipment and unfamiliar to a confident reader whose interests lie elsewhere.
Can scientific vocabulary help outside formal study?
It can help you follow an explanation, ask a clearer question and notice when a comparison needs more information. Choose terms connected to what you actually read or do. There is little benefit in displaying a specialist word when a simpler expression communicates the point accurately.
Why are common science words missing?
The numbered lists avoid repeating entries already allocated to earlier ages. Common words still belong in your explanations. Use the previous banks whenever they provide the foundation for a new term; the no-repeat rule concerns the published lists, not ordinary language use.
How do I know whether a lookup has worked?
Return to your original question. Can you explain the relevant sentence, connect the word to its example and identify an important condition? If one part remains unclear, write a specific follow-up question. Understanding can improve before every detail is settled.
The sequence and word audit
Age 18: 2,000 distinct listed entries. This volume occupies series positions 34,001–36,000. The published collection currently contains Ages 1–24, with 48,000 distinct listed entries across twenty-four banks.
The audit checks the numbered list entries, rather than every word in the article. Case, spacing, hyphens, apostrophes, accents and recorded spelling variants are normalised to catch duplicates. Established single words and conventional hyphenated headwords count as entries. Different meanings of the same spelling do not receive extra entries. Some useful derived forms are separate entries; the total is not a count of unrelated word families.
“Top” means an editorial selection for this reference project. It does not mean the most frequent words in a measured language corpus or the best 2,000 words for every reader. Sequence numbers locate entries in the collection; they are not importance scores or developmental measures.
Keep repeating useful words in real life. The non-repeating lists offer additional choices. They do not recommend withholding familiar language or learning 2,000 new words at each birthday.

Vocabulary Growth Guide for Age 18: Why, What and How
A page of technical labels can look like knowledge without yet explaining anything. You might name the components in a drawing but not know which part supplies, measures or controls something. The next step is not necessarily another definition. It may be a sentence connecting two ideas you already recognise.
Learn the term, identify its role, connect it with other ideas and reconstruct a short explanation before checking it against the source. This guide shows how to make vocabulary useful in technical reading without treating the word bank as a qualification. Its examples are reading exercises, not instructions for operating equipment or carrying out experiments.
Why relationships matter · What a useful concept note contains · Research and its limits · A worked example · A practical routine · Recognising progress
Why a list of nouns is not yet an explanation
“Fan, chamber, duct, sensor” gives four names. “The fan supplies air to the chamber” states a relationship. “The sensor measures a property of the air” adds a different relationship. Neither sentence tells you, on its own, whether the sensor controls the fan. That additional claim needs its own support.
Vocabulary becomes more useful when you can distinguish a component, a property, a process and a measurement. You are then less likely to mistake the name of an instrument for the quantity it measures, or the existence of a connection for proof of a particular cause. The important question is what each term contributes to the explanation.
Choose a topic you have a reason to understand. An interest in sound, materials, computing, plants or manufacturing can provide a question worth answering. You do not need to traverse the entire advanced bank before reading a useful introduction. Use the checked definitions and examples above as starting points, not as substitutes for a subject explanation.
What a concept note should help you do
Give the term a plain meaning and a job in this passage. Then connect it to something else with a verb: forms, supplies, measures, enters, follows or differs from. Be careful with causes. A source can show that two things occur together without establishing that one causes the other. Keep your connecting word no stronger than the evidence permits.
Add a boundary. A diagram may identify a component without providing performance data. A numerical value may name a measurement without identifying its uncertainty. A definition may explain a process without telling you whether that process happened in a particular specimen. These are different missing pieces, so they need different follow-up questions.
You can organise the note as a paragraph or as a small map of labelled relationships. For this purpose, the map is not decoration. Each connection should be readable as a meaningful statement. An unexplained line between two technical words may hide exactly the relationship you still need to learn.
What research says about reconstructing knowledge
Blunt and Karpicke’s 2014 study, Learning with Retrieval-Based Concept Mapping, examined undergraduate learning from educational texts in two experiments. Students practised retrieving material as paragraphs or concept maps. On a test one week later, both retrieval formats outperformed additional studying under the tested conditions, and the two retrieval formats did not differ. The study tested learning of text content, including inference questions, rather than this vocabulary bank.
The implication used here is modest: after studying an explanation, attempt to reconstruct its important relationships, then inspect and correct the result. This does not establish that diagrams always outperform prose, that every drawing is effective practice or that a single recall attempt produces expertise. The reading exercise below is an original application, not the research intervention.
Feedback matters to this proposed routine because an unchecked reconstruction can contain errors. Reopen the source, identify what you omitted or invented and revise your account. When the source itself is unclear, ask for a better explanation rather than repeatedly rehearsing a guess.
A worked example: from four labels to a connected explanation
Read this fictional description. “A fan sends air into a plenum. Two ducts carry air from the plenum to two display spaces. A sensor beside the first display records temperature. The description provides no information about automatic control.” These invented details are the complete source for the exercise. They are not a design specification or advice about preserving museum objects.
Locate the unfamiliar word. The plenum explanation earlier on this page identifies a chamber within an air-distribution system. In the fictional description, its useful connection is to the fan supplying air and the ducts carrying air away. You do not need the names of every possible mechanical component to explain that limited pathway.
Reconstruct the relationships. Without looking at the description, write three short statements. The fan supplies air to the plenum. The two ducts carry air from it to the display spaces. The sensor records temperature beside the first display. If you prefer a map, use those verbs on the connections rather than drawing unlabelled arrows.
Inspect a plausible addition. Suppose your reconstruction says, “The sensor controls the fan.” That may sound reasonable, but it is not established by the fictional source. The sensor is described as recording temperature. Recording a value and controlling another component are different functions. Remove the unsupported connection or turn it into a question.
Notice the location limit. A reading beside the first display is not automatically a measurement beside the second. The source names one sensor and one position. A faithful explanation preserves those details. It does not silently add a second sensor or claim that both spaces have identical conditions.
Write the missing question precisely. “Does the sensor only record temperature, or does it also send a control signal?” asks about a particular relationship. “How does everything work?” is much broader. The smaller question gives a teacher, colleague or technical source a clearer task to answer.
Change the layout without changing the logic. Imagine the second drawing places the plenum above rather than beside the fan. Keep the labels and stated connections the same. Can you still explain the pathway? This checks whether you are relying on the idea or merely remembering where a word appeared on the original page.
Transfer the method, not the conclusion. In another subject, a diagram might show a sequence of events rather than a flow of air. Read its key before assigning meaning to arrows. The useful habit is to identify and check relationships; the meaning of every arrow does not travel unchanged between diagrams.
How to build understanding without drowning in terminology
Begin with a short explanation from a suitable source. Identify its central question and select only the terms necessary to answer that question. A specialist passage that assumes too much background may need an introductory source first. Choosing that introduction is a useful adjustment, not a retreat from advanced learning.
Write a meaning note and a relationship note. The first explains the word. The second says what this particular source claims about the thing it names. Keep source details with both. This separates vocabulary knowledge from factual knowledge about an example and makes later checking easier.
After understanding the passage, put it aside and explain the main connection. A spoken explanation, a short paragraph or a simple labelled map can all serve the task. Mark uncertainty visibly. Do not fill an empty space with an impressive term merely to make the account look complete.
Return to the source and repair the precise error. Did you reverse a direction, omit a condition or confuse a measurement with a cause? Keep a brief correction note. On a later occasion, try another explanation that uses the term in a relevant setting. No fixed number of repetitions is promised here.
The Age 18 guide to higher-education and professional communication offers related support. A helper can ask “What does that connection mean?” and allow the learner to answer before supplying the missing idea.
What meaningful progress looks like
Look for an explanation with fewer unsupported links. You can identify what a term names, connect it to a process and state what the source does not tell you. Remembering the spelling remains useful, but it is only one part of this achievement.
When definitions are secure but the explanation is not, work on connecting sentences. When the relationships are clear but a technical label is hard to retrieve, practise that label with its plain explanation. When a source assumes background you lack, find the prerequisite idea. More copying of the same word is not the answer to every difficulty.
Keep the activity separate from practical competence. Reading an equipment term does not train someone to use that equipment, and recognising a biological term does not qualify someone to interpret a personal medical result. Use qualified help and the relevant instructions where the consequences require them.
From knowing the name to understanding the connection
Return to the Age 17 growth guide for retrieval and faithful paraphrasing. Continue with the Age 19 bank to explore how meanings travel between examples and settings. Familiar vocabulary from any volume remains welcome.
