The parent's guide to 11+ vocabulary

What examiners actually test, and how to prepare without tears.

Vocabulary is the single biggest differentiator in 11+ verbal reasoning and English papers. Unlike maths, it cannot be crammed in the final month — it is built through steady exposure. This guide explains what examiners actually test and how to prepare without tears.

What the 11+ actually tests

Across GL Assessment, CEM-style, Quest and independent school papers, vocabulary questions come in a handful of repeatable formats:

Question typeWhat it looks likePractise with
Synonyms"Which word is closest in meaning to opulent?"Synonym word list
Antonyms"Which word is most opposite to diligent?"Antonym word list
Cloze / missing wordsChoose the word that best completes a sentenceContext-based practice
Word rootsWorking out unfamiliar words from partsRoot words list
General knowledge EnglishCollective nouns, idioms, homophonesCollective nouns · Idioms

How many words does a child need?

Successful 11+ candidates typically have a working vocabulary noticeably ahead of the Year 6 average. The good news: exam papers draw heavily on a core of a few hundred "power words" — the ambitious synonyms for everyday ideas (big, small, happy, sad, brave, dishonest…). Mastering those groups covers a remarkable share of real questions.

What works (and what doesn't)

Works: little and often. Ten minutes a day beats a two-hour Sunday session. Words in groups. Words met in games and stories, then reused aloud.
Doesn't work: alphabetical word lists copied out by hand, cramming in the last half-term, and testing without teaching (which only proves what a child doesn't know).

The role of games

Children repeat what feels rewarding. A vocabulary game with streaks, badges and quick wins gets voluntarily replayed — and repetition is precisely what moves words from "seen once" to "owned". That is the entire design philosophy behind Lexi's Vault: every game mode (synonym card battles, antonym attacks, root-word decoding, daily challenges) is a disguised repetition engine.

A realistic timeline

WhenFocus
Year 4Reading widely + playful word games. No pressure.
Year 5 (autumn–spring)Systematic synonym groups, root words, daily 10-minute habit.
Year 5 (summer)Antonyms, cloze, idioms; start timed mini-tests.
Year 6 (run-up)Revision of personal "tricky words" — not new lists.

See our companion guide: how to build a daily vocabulary routine that sticks.
