A synonym list is useful until it teaches the wrong lesson: that similar words can be swapped freely.
A synonym ladder organises related words by strength, tone or exact meaning rather than pretending they are identical.
This Semantic Depth article expands the protected Top 100 Vocabulary List for Primary 5 (AL1 Grade) Advanced.
Build ladders, not piles
| Idea | Ladder |
|---|---|
| anger | irritated → annoyed → angry → furious |
| fear | uneasy → anxious → frightened → terrified |
| happiness | pleased → delighted → thrilled → overjoyed |
| movement | creep → walk → stride → hurry → sprint |
| certainty | possible → plausible → likely → certain |
The ladder is approximate, not mathematical. Context still decides.
Tone ladders
Some related words differ less in strength than in judgement: persistent may praise; stubborn may criticise. confident is usually positive; arrogant negative.
Cause ladders
Sad, disappointed, grief-stricken and embarrassed are not simply different strengths. Their causes differ. Good synonym work asks why the feeling exists.
The substitution test
- Write a sentence with the target word.
- Replace it with a neighbour.
- Ask what meaning or tone changes.
- Explain the boundary in one sentence.
Comprehension use
If several answer words seem possible, a synonym ladder helps calibrate intensity. The best word is the one supported by the passage, not the one highest on the ladder.
Composition use
Ladders help writers avoid melodrama. A minor delay may cause annoyance, not devastation. A serious betrayal may justify stronger emotion.

Maximum-Resolution Synonyms: A Semantic Map, Not a Thesaurus Heap
Words that look synonymous usually occupy neighbouring positions rather than the same point. One may differ in intensity, cause, judgement, formality, frequency, agency or typical collocation. High-resolution vocabulary learning therefore maps the neighbourhood.
Five Axes for Nearby Words
| Axis | Question | Example |
|---|---|---|
| intensity | How strong? | annoyed → angry → furious |
| cause | Why does the state exist? | disappointed vs embarrassed |
| judgement | Does the word praise or criticise? | persistent vs stubborn |
| register | How formal or specialised? | use vs utilise |
| collocation | What partners naturally fit? | draw a conclusion, reach a conclusion |
Build Neighbourhoods, Not Only Ladders
Some words cannot be placed on one straight intensity line. Anxious, fearful, apprehensive and uneasy overlap but differ in certainty, anticipation and strength. A semantic neighbourhood allows several axes at once.
The Swap Test
- Write a natural sentence with the target word.
- Replace it with a neighbour.
- Ask what changed: strength, cause, tone, grammar or collocation?
- Write the boundary explicitly.
- Create a second context where the neighbour becomes better.
Worked Boundary
“She was relieved when the doctor said the injury was minor” is precise because a prior worry has been reduced. “She was happy” is possible but loses the causal structure. “She was delighted” may overstate the emotional shape. The words overlap, but they do not preserve the same information.
Synonym Diagnostic
- What information is shared?
- What is different?
- Which word is stronger?
- Which carries a different judgement?
- Which has a different cause?
- Can both fit the same collocation?
- What context makes one clearly better?
Primary 5 to Primary 6 Transfer
Primary 6 questions often place several plausible words close together. Students who have semantic maps can select by boundary rather than familiarity, improving cloze, comprehension, composition and oral precision.
Return to the Primary 5 vocabulary hero. For ten target words, add three neighbours and one sentence explaining why each neighbour is not fully interchangeable.
