English Vocabulary · Cross-exam Academic English Beta

TOEFL · TOEIC · IELTS · IGCSE Vocabulary

This 1,600-word beta set supports learners preparing for TOEFL, TOEIC, IELTS, and Cambridge IGCSE English. Official specimen papers supply the primary occurrence evidence, so words shared across several programmes rise toward the beginning of the list. Overlap with school-grade, SAT, and GRE vocabulary is intentional because the same academic English serves several learning pathways.

A limited public specimen corpus does not contain 1,600 distinct, reliable teaching headwords. The remaining places therefore bridge from KSSR’s audited Grade 4–9 curricula using general English frequency and a fixed balance of nouns, adjectives, verbs, and adverbs. Every row reuses a reviewed meaning, complete example sentence, word-study note, and dictionary-style equivalents in all launch languages. The first release includes five cloze questions per page; reading workshops will be added only after their English passages and translations are separately reviewed.

About this cross-exam English set

TOEFL, TOEIC, IELTS, and Cambridge IGCSE English use different formats, but all require learners to understand precise vocabulary in context. TOEFL and IELTS emphasize academic reading and communication; TOEIC emphasizes workplace and everyday communication; IGCSE English asks students to interpret, analyze, and communicate through school-level texts and tasks. This combined set concentrates on useful language that can transfer across those pathways.

The ordering is evidence-led rather than alphabetical. Words found in official public specimen materials—especially words occurring across more than one programme—receive the strongest ranking. Because a limited specimen corpus cannot provide 1,600 distinct reliable teaching headwords, the remainder is transparently bridged from KSSR’s audited Grade 4–9 vocabulary using general English frequency and a fixed part-of-speech balance. This is an independent study resource, not an official product of any testing organization.
