A theme-based companion to the main Vocabulary — 964 High-Frequency Words page, which is organised alphabetically. This page instead groups words by topic — useful when a specific essay theme (governance, communication, logic, change) needs a matching word bank. All entries below are written fresh for this page: plain-English meaning, 2–3 synonyms, 1–3 antonyms, and a natural example sentence.
