11+ Vocabulary by Age: What to Focus on at 8, 9, and 10

“Is my child's vocabulary good enough for their age?” is one of the hardest questions to answer, because there's no single test you can run at home and no official checklist schools hand out.

What you can do is know roughly what's realistic and useful at each stage, so you're not cramming everything into the final year or, just as easily, leaving it too late to start.

Most children sit the 11+ in Year 6, at age 10 or 11, but the vocabulary that gets tested is built up over several years beforehand. Here's what to focus on at each age, and why trying to rush the process rarely works.

Age 8 (Year 3/4): Build the Habit, Not the List

At 8, the goal isn't memorising exam words. It's building the reading habit that makes everything later easier. Children this age are still developing fluency, and vocabulary grows almost entirely through exposure: what they read, what they hear, what gets explained to them in passing.

What “good” looks like at this stage:

• Reading a range of fiction confidently, not just one favourite series on repeat
• Asking what unfamiliar words mean, or having a go at guessing from context
• Using slightly more varied words in speech and writing than the year before, not just “nice” and “big”, but the occasional “enormous” or “delighted”

What to focus on:

• Wide, varied reading, which matters more than any word list at this age
• Talking about words that come up naturally, in books, on walks, at the dinner table
• Short, low-pressure games rather than formal study: matching, odd-one-out, “what's another word for...”

There's no need to introduce exam-style vocabulary yet. Verbal reasoning and formal 11+ preparation aren't part of the primary curriculum at this age, and pushing exam words too early tends to produce memorised definitions rather than real understanding: words a child can recite but not actually use.

Age 9 (Year 4/5): Start Widening Deliberately

By 9, most children have the reading fluency to start widening their vocabulary more deliberately, and this is a sensible age to introduce the idea of word-learning as something they do on purpose, not just something that happens by accident.

What “good” looks like at this stage:

• Understanding words with more than one meaning (a word like “sharp” meaning both a blade and a taste)
• Recognising some common prefixes and suffixes, and having a go at working out unfamiliar words from them
• Starting to notice synonyms, that “happy”, “delighted” and “content” aren't quite the same, even though they're related

What to focus on:

• Introducing synonyms and antonyms in a low-pressure way, since games work better than worksheets at this age
• Reading slightly outside comfort zone: a wider range of authors, some non-fiction, the odd older or more challenging book
• Short, regular sessions rather than occasional long ones. Five or ten minutes most days beats an hour once a week

This is also a sensible point to introduce an app or a short daily habit, since children this age generally have the attention span for it without it feeling like homework. The goal isn't a fixed word count. It's building the muscle of noticing and using new words.

Age 10 (Year 5/6): Focus Where the Exam Actually Focuses

By 10, most children preparing for the 11+ are either in the exam year or the year immediately before it, and this is when it makes sense to focus vocabulary work more specifically on what actually comes up in the exam.

What “good” looks like at this stage:

• Comfortably understanding synonyms, antonyms and word relationships, the core of verbal reasoning vocabulary questions
• Working out unfamiliar words from context under some time pressure, not just at leisure
• A vocabulary noticeably broader than a typical same-age reader, built up from the previous couple of years rather than crammed in a few months

What to focus on:

• Targeted vocabulary practice alongside continued wide reading, since both matter, but exam-style practice becomes more relevant now
• Timed exposure to synonym and antonym questions, since the exam tests vocabulary under time pressure, not just knowledge in isolation
• Consistency over intensity: regular short sessions across the year outperform a panicked sprint in the final months

It's worth saying clearly: there's no magic number of words that guarantees exam success, and chasing an ever-longer list at this stage usually adds less value than it feels like it should. A child who's read widely and practised consistently since 8 or 9 will generally be in a stronger position than one starting from scratch with a huge list at 10, however comprehensive that list looks on paper. If you want a starting point that's curated rather than padded, our list of the 500 most important 11+ words is organised by difficulty.

The Pattern Across All Three Ages

If there's one theme across 8, 9 and 10, it's this: vocabulary for the 11+ isn't something you build in a term. It's the compound result of years of reading and small, regular habits, with the focus shifting from wide (at 8) to deliberate (at 9) to exam-relevant (at 10).

Starting late isn't fatal. Plenty of children make good progress in a single focused year, but it does mean more concentrated effort is needed to cover ground that would otherwise have built up gradually.
