11 Plus Vocabulary Hub 2026: 500+ Essential Words for GL Assessment & CEM
A strong vocabulary is the single highest-return preparation activity for the 11 plus exam — it directly improves performance in Verbal Reasoning, English comprehension, creative writing, and across every section of CEM. This hub brings together 500+ essential words organised by theme, complete with synonyms, antonyms and example sentences, plus the exact daily routine that builds genuine vocabulary depth over time. All free, no registration required.
Whether your child is preparing for GL Assessment or CEM, this vocabulary hub is designed to work alongside our Verbal Reasoning Hub and English Hub for complete exam preparation.
Why Vocabulary Is the Master Key to 11 Plus Success
Of every preparation activity available for the 11 plus exam, vocabulary building has the broadest impact and the longest-lasting return. Unlike a specific question-type strategy — which can be taught in a single session — genuine vocabulary depth takes months to build and cannot be effectively crammed in the final weeks before the exam.
Exactly How Vocabulary Affects Your Score
- Synonyms (~15–20% of GL VR paper): Direct vocabulary test — knowing the word determines the answer
- Antonyms (~12–15%): Requires precise understanding of opposite meanings
- Analogies (~10–15%): Requires knowing the exact meaning of both words in the relationship
- Hidden words and classification: Vocabulary recognition speeds up pattern identification
- English comprehension: Wider vocabulary directly improves reading speed and inference accuracy
- Creative writing: Precise, varied vocabulary is one of the most heavily rewarded markers in GL English
- CEM cloze passages: Selecting the correct word from options requires contextual vocabulary knowledge
- CEM numerical word problems: Misreading "perimeter" as "area" or "increase" as "decrease" costs marks regardless of maths ability
Combined, vocabulary directly or indirectly influences over 60% of the total 11 plus assessment across both GL Assessment and CEM formats.
📌 Start Vocabulary Before Anything Else
Of all 11 plus preparation activities, vocabulary should begin first — ideally 12 to 18 months before the exam — because it is the one area that cannot be rushed. Question-type strategies for Verbal Reasoning and Non-Verbal Reasoning can be effectively taught in 6 to 8 weeks. Genuine vocabulary breadth requires sustained daily exposure over many months. See our Verbal Reasoning Hub for how vocabulary connects to specific question strategies.
11 Plus Vocabulary Word Groups by Theme
Learning vocabulary in thematic groups — rather than random alphabetical lists — builds the semantic networks that make recall faster and more reliable under exam pressure. Each group below includes the synonym progression (similar words moving from simple to more sophisticated) and common antonyms.

Common Prefixes and Suffixes for the 11 Plus
Understanding prefixes and suffixes allows students to deduce the meaning of unfamiliar words encountered for the first time in the exam — an essential skill since no vocabulary list can cover every possible word that might appear. This is particularly valuable for analogy and classification questions, and for CEM cloze passages.
High-Value Prefixes
| Prefix | Meaning | Example Words |
|---|---|---|
| un- | not / opposite of | unhappy, unable, unaware |
| dis- | not / reverse of | disagree, disappear, dishonest |
| mis- | wrongly | misunderstand, misplace, mislead |
| pre- | before | predict, prevent, preview |
| re- | again | rewrite, return, rebuild |
| anti- | against | antisocial, antidote, antiseptic |
| inter- | between | international, interact, interrupt |
| over- | too much | overcook, overreact, overestimate |
| under- | too little / below | underestimate, underground, undercook |
| sub- | under / below | submarine, subway, substandard |
High-Value Suffixes
| Suffix | Meaning / Function | Example Words |
|---|---|---|
| -tion / -sion | turns a verb into a noun | celebration, decision, action |
| -ment | turns a verb into a noun | development, agreement, movement |
| -ness | turns an adjective into a noun | happiness, kindness, darkness |
| -ous / -ious | full of / having | dangerous, courageous, ambitious |
| -ive | having the nature of | active, creative, persuasive |
| -ful | full of | beautiful, thoughtful, careful |
| -less | without | careless, fearless, hopeless |
| -able / -ible | able to be | comfortable, visible, reliable |
✅ Practise Prefix and Suffix Deduction
When your child meets an unfamiliar word in a sample test, encourage them to break it down: identify the root word, then the prefix or suffix, and deduce a probable meaning before checking a dictionary. This deduction skill is directly rewarded in 11 plus exams where unfamiliar words will inevitably appear — no word list can cover every possible exam word. Practise this skill using passages from our English Hub.
The 30 Most Commonly Misspelt 11 Plus Words
Spelling accuracy matters in creative writing and SPaG (spelling, punctuation and grammar) sections of the 11 plus English paper. These words appear repeatedly across exam scripts as common spelling errors — focused practice on this specific list produces measurable improvement.
| Word | Common Error | Word | Common Error |
|---|---|---|---|
| necessary | "neccessary" | parliament | "parliment" |
| separate | "seperate" | privilege | "priviledge" |
| definitely | "definately" | recommend | "reccommend" |
| embarrass | "embarass" | rhythm | "rythm" |
| accommodate | "accomodate" | successful | "succesful" |
| occurred | "occured" | until | "untill" |
| beginning | "begining" | weird | "wierd" |
| business | "buisness" | February | "Febuary" |
| conscience | "concience" | guarantee | "garantee" |
| government | "goverment" | occasionally | "occasionaly" |
| immediately | "imediately" | received | "recieved" |
| independent | "independant" | environment | "enviroment" |
| knowledge | "knowlege" | thorough | "thurough" |
| maintenance | "maintainance" | vegetable | "vegtable" |
| mischievous | "mischievious" | persuade | "perswade" |
⚠️ How to Practise Spelling Effectively
Avoid passive copying out of words — this produces minimal retention. Instead, use the "look, cover, write, check" method: look carefully at the word, cover it, write it from memory, then check against the original. For multi-syllable words, break the word into syllables and learn each part separately before combining. A weekly mini-test of 10 words from this list builds spelling accuracy systematically over the preparation period.
Tier 2 Academic Vocabulary for Comprehension and Exam Instructions
Tier 2 vocabulary refers to high-utility academic words that appear across many contexts but aren't used in everyday casual speech — words like "analyse," "demonstrate" and "consequence." The 11 plus exam relies heavily on Tier 2 vocabulary in both comprehension passages and the wording of instructions themselves. A student who misunderstands the instruction word will answer the wrong question even with strong subject knowledge.
Essential Tier 2 Words for Understanding Exam Instructions
| Word | Meaning in Exam Context |
|---|---|
| identify | find and clearly state |
| justify | give reasons supporting your answer |
| infer | work out something not directly stated, using clues |
| summarise | state the main points briefly in your own words |
| analyse | examine in detail, breaking down into parts |
| compare | identify similarities AND differences between things |
| demonstrate | show clearly through evidence or example |
| evaluate | judge the value, quality, or significance of something |
| significant | important or notable |
| consequence | a result or effect of an action |
📌 Why This Matters Most for Comprehension
Students who confidently understand Tier 2 instruction words answer the exact question asked rather than a related but different question — one of the most common sources of lost marks in 11 plus English. Practise these words explicitly using comprehension passages from our English Hub.
The 10-Minute Daily Vocabulary Routine
Consistency matters more than session length. 10 minutes daily for 10 to 12 months produces dramatically better results than occasional 1-hour cramming sessions, because spaced, regular exposure is fundamentally how long-term memory works.
- Review yesterday's words (2 minutes): Spaced repetition — quickly recall the spelling, meaning, synonym and antonym of words learned the previous day.
- Learn 7–10 new words (5 minutes): Choose one thematic group above. For each word, learn the spelling, the meaning, one synonym and one antonym together.
- Use each word in an original sentence (3 minutes): Active use cements retention far better than passive reading. Encourage sentences related to the child's own life or interests.
Weekly Structure
| Day | Activity |
|---|---|
| Monday–Friday | 10-minute daily routine (review + new words + sentences) |
| Saturday | Mini-test on the week's words: spelling, definition, synonym, antonym |
| Sunday | Apply the week's words in a Verbal Reasoning practice test or creative writing piece |
✅ The Four-Part Mastery Test
A word is genuinely learned only when your child can do all four without hesitation: spell it correctly, define it in their own words, give a synonym and antonym, and use it correctly in an original sentence. Testing only spelling or only definition gives an incomplete and misleading picture of true vocabulary mastery.
How to Use This Vocabulary Hub Effectively
This hub works best as part of an integrated preparation strategy connecting vocabulary directly to practice tests, rather than as an isolated activity.
Recommended Sequence
- Start with the Courage and Intelligence word groups in Weeks 1–2 — these appear most frequently in 11 plus synonym and antonym questions
- Move through Happiness, Sadness and Anger groups in Weeks 3–4 — emotional vocabulary supports both VR and creative writing
- Cover Size and Speed groups in Weeks 5–6 — frequently used in analogies and classification questions
- Learn prefixes and suffixes from Week 3 onwards, alongside the thematic groups — this builds the deduction skill needed for unfamiliar words
- Drill the misspelt words list weekly throughout, 10 words per week, repeating the full list every 6 weeks
- Introduce Tier 2 instruction vocabulary once comprehension practice begins — ensure your child understands every instruction word before attempting practice papers
Apply Vocabulary Directly in Practice Tests
Vocabulary learned in isolation has limited value until applied in exam-style questions. After each week of vocabulary learning, complete a short Verbal Reasoning synonym/antonym practice test specifically using that week's words, then a comprehension passage from the English Hub to see the vocabulary in context.

Frequently Asked Questions About 11 Plus Vocabulary
Why is vocabulary so important for the 11 plus exam?
Vocabulary directly affects synonyms, antonyms, analogies, hidden words and classification questions in Verbal Reasoning (over 60% of the GL VR paper), reading comprehension speed and inference, creative writing quality, and in CEM specifically, cloze passages and numerical word problems. No other preparation activity has equivalent reach across the entire exam.
How many words should my child learn for the 11 plus?
Target 1,500 to 2,000 words beyond a child's existing vocabulary. Learning 7 to 10 new words daily for 12 months produces approximately 2,500 to 3,500 additional words. Quality matters as much as quantity — knowing 1,000 words thoroughly beats briefly seeing 3,000 without retention.
What is the best way to learn 11 plus vocabulary?
Combine four elements: learn words in thematic groups, learn synonym AND antonym together for each word, use each word in an original sentence, and review previously learned words regularly through spaced repetition. A daily 10-minute routine sustained for 10–12 months produces the best results.
What types of words appear most often in the 11 plus exam?
Words describing character and emotion (courage, intelligence, happiness, sadness, anger), size and scale, speed and movement, formal academic Tier 2 vocabulary used in comprehension passages, and words with common prefixes and suffixes. Learn these in thematic clusters using our Verbal Reasoning Hub.
Is the same vocabulary tested in GL Assessment and CEM?
Substantial overlap exists, but CEM emphasises vocabulary breadth more heavily — testing it across cloze passages, word problems and non-verbal instructions, not just Verbal Reasoning and English. See our CEM Assessment Guide for CEM-specific vocabulary strategy.
How early should vocabulary learning start for the 11 plus?
Start vocabulary first, ideally 12 to 18 months before the exam — it is the one area that cannot be crammed. Question-type strategies can be taught in weeks; genuine vocabulary depth requires sustained months of exposure. Begin in Year 4 or early Year 5 for the strongest results.
What are synonyms and antonyms and why do they matter for 11 plus?
A synonym shares meaning with another word ("happy"/"joyful"); an antonym is opposite ("happy"/"sad"). Together these form 15–20% of the Verbal Reasoning paper and support analogy and classification questions too. Learn every new word with a synonym and antonym simultaneously.
What are the most commonly misspelt words in the 11 plus exam?
Necessary, separate, definitely, embarrass, accommodate, occurred, beginning, business, conscience, government, immediately, parliament, privilege, recommend, rhythm, successful, until, weird, February — see the full 30-word list above with common error patterns.
Should my child memorise word lists or learn vocabulary through reading?
Both — combined. Structured lists give efficient, targeted exposure; wide reading (including classic literature) builds deeper, flexible word knowledge through natural context. Combine 10 minutes daily word-list learning with 20–30 minutes daily reading across varied genres.
How can I test whether my child has actually learned a vocabulary word?
A word is genuinely learned when a child can spell it, define it accurately, give a synonym and antonym, and use it correctly in an original sentence — all without hesitation. Weekly mini-tests covering all four elements give the most accurate picture of mastery.
What is Tier 2 vocabulary and why does it matter for the 11 plus?
Tier 2 words are high-utility academic words ("analyse," "demonstrate," "significant") distinct from everyday Tier 1 words and subject-specific Tier 3 terms. The 11 plus relies heavily on Tier 2 vocabulary in comprehension passages and instruction wording — students who misunderstand instructions answer the wrong question even with strong subject knowledge.
How does vocabulary help with 11 plus non-verbal reasoning?
NVR instructions are written in words ("rotate," "reflect," "translate"). A student who misreads these instructional terms applies the wrong transformation even with strong spatial ability. This is a frequently overlooked but valuable preparation step, especially for CEM where instructions vary mid-paper. See our Non-Verbal Reasoning Hub.
What vocabulary resources does Omishaan UK provide for free?
500+ words across 7 themed groups with synonyms, antonyms and example sentences, prefix and suffix lists, a 30-word commonly-misspelt list, Tier 2 instruction vocabulary, a structured daily routine, and direct links to Verbal Reasoning and English practice tests. All completely free, no registration.
How long should daily vocabulary practice take for the 11 plus?
10 minutes daily is sufficient and more effective than longer, less frequent sessions: 2 minutes reviewing previous words, 5 minutes learning 7–10 new words with synonyms/antonyms, 3 minutes using new words in sentences. Sustained for 10–12 months, this consistent habit outperforms occasional cramming sessions.
