Why This Is the Secondary 1 G2 Advanced Foundation

This list deliberately avoids the 300 headwords reserved for the Secondary 2, Secondary 3 and Secondary 4 G2 Advanced lists. Its job is different: build control of description, judgement, learning behaviour, register and independent expression before later G2 vocabulary becomes more analytical and abstract. It is also not a duplicate of the general SEC G2 Advanced master.

How to Use This Top 100

Learn meaning and grammatical role together. The list intentionally includes adjectives, adverbs and nouns from related semantic areas because Secondary 1 students need to control form as well as meaning. Compare precise, precisely and precision; dedicated and dedication; attentive, attentively and attentiveness. Related forms are not duplicates when the learning target is grammatical control.

G2 Progression Rule

Secondary 1 is the foundation layer. Secondary 2 adds broader analysis and academic process vocabulary. Secondary 3 increases abstraction, systems and evaluation. Secondary 4 adds higher-level argument, evidence and judgement. The four year lists should therefore be read as a ladder, not four interchangeable Top 100 pages.

Secondary 1 G2 in the SEC Ecosystem

Secondary 1 is a school year; G2 is a subject level. For the 2027 Singapore–Cambridge Secondary Education Certificate, G2 English Language is syllabus K200. This year-level master builds foundations for the broader SEC G2 Advanced Vocabulary master. It does not imply that every Secondary 1 student takes English at G2.

How to Use This Top 100

Work in small sets. For each word, explain the meaning in ordinary English, identify its word class, learn one natural collocation, contrast a near-neighbour, retrieve it from memory and use it in a new context. Then return after a delay. A word becomes useful when it can be selected independently during reading, writing or speaking.

Vocabulary by Language Job

Character and feelings: apprehensive, assertive, attentive, compassion, considerate, empathy, genuine, optimistic, reluctant, remorse, resilient, sincere, thoughtful. Reasoning and evidence: assess, credible, discern, evaluate, evident, implication, insight, interpret, justify, objective, plausible, relevant, sceptical, valid. Action and problem-solving: adapt, anticipate, clarify, collaborate, contribute, demonstrate, enhance, foster, fulfil, prioritise, reconcile, reinforce, resolve, restore.

Judgement: adequate, appropriate, beneficial, compelling, crucial, detrimental, feasible, practical, prudent, significant, sustainable, worthwhile. Responsibility and relationships: commitment, compromise, inclusive, influence, initiative, integrity, impartial, responsible, restraint, tolerate, transparent. Writing control: accurate, coherent, convincing, elaborate, logical, meaningful, precise, reliable.

The Secondary 1 G2 Package

This master owns the core Top 100. The Composition Vocabulary page owns writing transfer. Idioms owns fixed and figurative language. Phrasal Verbs owns multi-word grammar and natural usage. Why Learn owns the rationale. Learning Methods owns retrieval, spacing, diagnosis and maintenance.
