What Is This Hub?
This is the starting page for eduKateSG’s Secondary 1–4 SEC G3 Advanced Vocabulary series.
There are four year-level lists:
- 100 words for Secondary 1
- 100 different words for Secondary 2
- 100 different words for Secondary 3
- 100 different words for Secondary 4
That gives students a 400-word progression from Secondary 1 to Secondary 4.
The main idea: The vocabulary becomes harder as you move up the years. The instructions stay simple.
What Changes from Secondary 1 to Secondary 4?
| Level | Main Focus | In Simple Terms |
|---|---|---|
| Secondary 1 | Control | Choose stronger words and use them naturally. |
| Secondary 2 | Analysis | Explain evidence, relationships and reasoning more precisely. |
| Secondary 3 | Argument | Handle different viewpoints, assumptions and interpretations. |
| Secondary 4 | Precision | Control nuance, rhetoric and sophisticated vocabulary under examination pressure. |
Secondary 1 G3 Advanced
Start here if you are in Secondary 1.
This level builds advanced vocabulary that is still easy to connect to familiar situations.
You will meet words such as candid, diligent, diplomatic, ingenious, persistent, precise, strategic and tactful.
For example:
The class leader gave tactful feedback about the confusing introduction.
Why tactful? Because the leader is giving criticism while trying not to cause unnecessary offence.

Secondary 2 G3 Advanced
Secondary 2 moves from strong expression towards analysis.
You begin using vocabulary to discuss evidence, comparison, cause, inference and reasoning.
For example, compare:
| Anecdotal | Empirical |
|---|---|
| Based on an individual story or experience. | Based on observation or experience gathered for investigation. |
A personal story can be useful. It does not automatically prove what happens to everyone.

Secondary 3 G3 Advanced
Secondary 3 adds argument and evaluation.
Students need language for assumptions, competing ideas, interpretation and the strength of an argument.
Compare:
| Cogent | Vehement |
|---|---|
| Clear, logical and convincing. | Expressed with strong feeling or force. |
An argument can be vehement without being cogent. Speaking strongly does not automatically make the reasoning strong.

Secondary 4 G3 Advanced
Secondary 4 is the most demanding year-level list.
The focus is precision: understanding difficult vocabulary in reading and using advanced vocabulary selectively in writing and speaking.
A useful Secondary 4 rule:
Recognise widely. Use selectively.
You may understand a difficult word before you are ready to use it naturally. That is normal.

Why Not Use the Same 100 Words Every Year?
Because students need progression.
If Secondary 1, 2, 3 and 4 all use nearly the same list, students keep revising instead of expanding.
In this series, each year has its own 100 headwords.
Earlier vocabulary is still used in examples and revision. It simply does not take another place in the next year’s Top 100.
What Does “Advanced Vocabulary” Mean?
It does not mean choosing the longest word.
It means having a more precise choice when a simple word is too vague.
Example
Compare this:
The leader was good when she spoke to the unhappy group.
Now ask what good actually means.
- Candid: she was honest and direct.
- Tactful: she handled a difficult truth carefully.
- Diplomatic: she managed disagreement without causing unnecessary offence.
The advanced word is useful because it tells us how she was good.
Better vocabulary = more precise meaning.
It does not mean more complicated sentences.
How Should I Learn the Words?
Do not start with all 100.
Start with five.
- Read the meaning.
- Read the example.
- Close the page.
- Explain the word in your own words.
- Write a different sentence.
- Check your sentence.
- Return to the word a few days later.
How Do I Know If I Really Know a Word?
Ask yourself:
| Check | Question |
|---|---|
| Meaning | Can I explain it simply? |
| Context | Can I understand it in a new passage? |
| Collocation | Do I know what words naturally go with it? |
| Sentence | Can I use it without copying the example? |
| Contrast | Can I explain how it differs from a similar word? |
| Writing | Can I use it only when it improves the sentence? |
| Speaking | Can I use it and explain it naturally? |
How Does This Help Composition?
Write your idea first. Improve the vocabulary second.
Do not begin a composition by deciding that you must use ten advanced words.
For example:
She told him that his plan had a problem.
This may already be correct.
If the situation requires greater precision:
She gave a candid assessment of the plan’s weakness.
Or:
She gave a tactful explanation of the problem and suggested a repair.
Both are stronger only because they communicate a more specific meaning.
How Does This Help Comprehension?
When you meet an unfamiliar word:
- Read the whole sentence.
- Read the sentence before it.
- Read the sentence after it.
- Ask what is happening.
- Look for the writer’s attitude.
- Try a simple meaning in place of the word.
Context often gives you enough information to make a sensible inference even when you have never memorised the word.
How Does This Help Oral Communication?
Answer the question first.
Give a reason.
Give an example.
Use an advanced word only if it fits naturally.
Then be ready to explain the same idea in simpler English. If you can paraphrase the word, you probably understand it better than if you can only repeat a memorised sentence.
What Is SEC G3?
SEC is the Singapore-Cambridge Secondary Education Certificate.
G3 is a subject level.
Secondary 1, 2, 3 and 4 are school years.
They are not the same thing.
These are eduKateSG teaching lists, not an official prescribed SEAB vocabulary bank. Students should use the official syllabus for their examination requirements.
