11+ vocabulary: The words your child needs and how to build them

Vocabulary is one of the most reliable predictors of 11+ performance across English, verbal reasoning, and comprehension. It's also easy to underestimate, because children who read fluently often have stronger vocabulary than their grade suggests, and that floor protects them right up to the day they meet a paper containing "obstinate," "reciprocal," and "vehemently."

This guide covers what kind of words appear on 11+ papers, where vocabulary shows up across the test, and a realistic home routine that builds genuine word knowledge over the nine to twelve months before the exam. The aim isn't to drill 500 flashcards. It's to give your child enough exposure that unfamiliar words feel manageable rather than alarming.

11+ vocabulary sits at roughly upper-Key Stage 2 to lower-Key Stage 3 level: Words a strong Year 7 reader would expect to know. They're not obscure or archaic, but they're a step beyond standard primary classroom language. Think "perplexed" rather than "confused," "meander" rather than "wander," "reluctant" rather than "unwilling."

Neither GL Assessment nor ISEB publishes a defined vocabulary list, but the words children tend to encounter in 11+ verbal reasoning practice cluster around three areas: descriptive adjectives, action verbs with specific connotations, and abstract nouns. Children with a wide reading habit pick most of these up incidentally. Children whose reading is narrow (one series, one genre) often have strong fluency but a thin vocabulary ceiling, which is what verbal reasoning is designed to find.

The test also rewards understanding of word relationships, not just meanings. A child who knows "jubilant" means happy gets one mark. A child who also knows it sits at the strong end of a happy-to-ecstatic scale, opposite "despondent," gets the synonym, antonym, and analogy questions in one go.

Vocabulary doesn't sit in its own section. It threads through almost every part of an 11+ paper, which is why building it produces compounding returns across the test.

That last row catches parents out. A child confident with maths but slow at reading loses marks on word problems not because the maths is hard, but because they've misread "twice as many as" or skipped "remainder." Vocabulary practice helps maths scores too.

There's no fixed list every 11+ board uses, and estimates of a working 11+ vocabulary vary widely. Many children entering Year 6 from a reading-rich household already have a strong working bank; the work is filling gaps, not building from scratch.

The gaps tend to cluster in four areas: precise emotional vocabulary (jubilant, despondent, indignant), descriptive verbs (trudge, dart, hesitate), abstract nouns (perseverance, ambiguity, integrity), and word roots that unlock unseen words (bio-, geo-, -ology, -graph). Targeting these directly gets you more lift than a generic flashcard deck.

A realistic pace is a handful of new words a week, with regular review of words from previous weeks. Steady additions across Year 5 and Year 6, plus the much larger number picked up through reading, tend to stick. Cramming dozens of words a week in the last month before the test doesn't stick and won't transfer to unseen passages.

Five vocabulary activities, used in rotation across the week. Each is short, low-pressure, and tied to something children find at least mildly interesting. The goal is exposure and active use, not testing.

One of the biggest drivers of vocabulary growth is reading material that contains words the child doesn't already know. If every book is comfortable, they're not meeting new words. Suggest one current-favourite book (for fluency and enjoyment) and one stretch book per fortnight: a classic, a non-fiction title, or a children's newspaper like First News.

Fifteen to twenty minutes a day matters more than a longer session at the weekend. Daily exposure is what builds incidental vocabulary.

When your child meets a word they don't know in reading, they add it to a shared word jar (a piece of paper in a kitchen jar) or a notebook. Once a week, take five words out and use them in dinner-table conversation. Three weeks later, revisit the same five.

This is just spaced repetition without the flashcard app. The reason it works is that the child meets each word in three different contexts: the original book, conversation, and review. Three encounters is roughly when a word moves from passive to active recall.

A child who knows "bio" means life can work out biology, biography, biodegradable, antibiotic, symbiosis, and a dozen other words they've never seen. Eight to ten root families do most of the work for 11+ level vocabulary.

The core set to teach: bio (life), geo (earth), aqua/hydro (water), chrono (time), -ology (study of), -graph (write/draw), tele (far), trans (across), sub (under), super (above). Spend two minutes a session on one root, with three example words. Many children find this interesting because it makes vocabulary feel decodable rather than random.

Scrabble, Bananagrams, Boggle, Codenames, and crosswords all force active retrieval of vocabulary under mild pressure, which is closer to exam conditions than passive reading. They also normalise the idea that vocabulary is a useful tool, not just a thing children get tested on.

A twenty-minute weekend game is worth a fifteen-minute practice paper at this stage of preparation. Kids who associate words with fun show up to the exam less anxious.

Once a week, pick a target word and build a chain of synonyms ranked by strength. For "happy": content → pleased → cheerful → joyful → elated → ecstatic. Then build the opposite chain: discontent → glum → sad → miserable → despondent → wretched.

This is the exact skill the synonym, antonym, and analogy questions test. Children who've built chains can answer "what's the closest synonym to elated?" in two seconds instead of ten, which adds up across a timed paper.

Vocabulary that gets used sticks. Vocabulary that's only read or recognised fades. The simplest way to push words into active recall is to give your child a writing prompt once a week (a story opening, a description, a diary entry) and ask them to use three of their word-jar words naturally.

This also doubles as creative writing practice, which is on the 11+ paper for many independent schools, so the time isn't a vocabulary-only investment.

The most common mistake is starting too late and then panicking. Vocabulary is slow-burn, not crammable. Six weeks before the test isn't enough time to build new word knowledge that transfers to unseen passages, no matter how much time per day you put in.

The second mistake is over-reliance on definitions. A child who can recite "ambiguous means unclear" but can't use the word correctly in a sentence won't reliably spot the right synonym under exam pressure. Definitions are the start of vocabulary learning, not the end.

The third is ignoring reading. Some families lean entirely on workbooks and never push reading volume. Workbooks teach you the question format. Reading is what gives you the vocabulary you need to answer the questions. Both matter, but reading does the heavier lifting.
