Flashcard word list
Writing — academic vocabulary from our Discussion samples
120 words
How this list was built
This deck holds 120 words: 100 hand-written academic entries from Reach120's curated list, plus the 20 words used across the widest range of our 142 Academic Discussion sample responses. They are academic topic and reporting vocabulary — the words a discussion response is written ABOUT. They are not hedges, stance markers or connectives: those are function words the lexicon filters out by design, and the phrasal ones are multi-word items nothing mines yet, so no deck here teaches them. Reach120 wrote this practice material for the 2026 format — it is not ETS content, and any band figure beside it is a Reach120-scored estimate, not an ETS score.
