Odd-one-out questions test category recognition, and the good news for parents is that examiners reach for the same families of categories again and again. Once your child knows what those families are and how to check them quickly, this Verbal Reasoning type becomes one of the fastest points on the paper. In GL Assessment papers the task is usually phrased as Odd One Out or Odd Word Out: three of the words go together and two do not, and the two that do not belong are the answer. Bond labels this among its Type A to U question set, and knowing the exact type means your child can practise it deliberately rather than hoping to recognise it on the day.
How the odd-one-out question actually works
The standard GL format gives five words. Three share a hidden connection by meaning, and the odd two are the ones that break the pattern. The trap is that the answer is the pair that does not belong, not the pair that does — many children rush and circle the matching group instead. Because GL papers are multiple-choice with a separate answer sheet and roughly a minute per question (often 35 to 50 seconds once you allow for the harder types), speed matters. The reliable method is: read all five words, ask "what do most of these have in common?", name the category out loud in your head, then find the two that fall outside it.
Categories examiners reach for
Meaning-based groupings dominate. If your child memorises the common families, half the work is done before they even read the options. Expect to see:
- Types of food — apple, pear, plum, peach, carrot (fruit versus vegetable).
- Musical instruments — violin, drum, flute, trumpet, window.
- Colours mixed with shapes — red, blue, square, green, yellow.
- Vehicles, professions, weather, sports and animals.
- Body parts, furniture, metals, relatives and units of time.
A useful drill is to sort word lists into categories at home — it builds the vocabulary and the sorting instinct at the same time. Our free worksheets group odd-one-out practice by category so children meet each family repeatedly.
A quick reference table of common groupings
| Category shown | The odd pair breaks it by... | Example |
|---|---|---|
| Fruit | being a vegetable | grape, cherry, onion, lemon, leek |
| Wild animals | being farm/pets | tiger, wolf, sheep, bear, cat |
| Things that fly | staying on the ground | eagle, plane, train, kite, car |
| Hot words | meaning cold | boiling, warm, icy, roasting, chilly |
The harder, abstract variant
Some odd-one-out questions are not about meaning at all — they are about the letters and sounds in the words. These are the ones that catch children who only ever look at meaning. The odd pair might be defined by a spelling or phonetic feature rather than a category. Watch for:
- Syllable count — four one-syllable words and one with two.
- Silent letters — only some words contain a silent letter (knee, wrist, lamb).
- Hidden smaller words — most words contain a smaller word, one does not.
- Vowel patterns — words that all contain a double letter except one.
- Rhyme or first-letter groups — words that begin with a vowel versus a consonant.
Teach the golden rule: if the obvious meaning category does not fit, look at the words themselves, not what they mean. Switching between the "meaning lens" and the "letters lens" is the single skill that separates confident pupils from stuck ones on this type.
Common mistakes and traps
Examiners plant red herrings deliberately. Coach your child to avoid the three classic slips:
- Circling the group, not the odd pair. Re-read the instruction: you want the two that do not belong.
- Stopping at the first connection. Two words might share a colour theme while three share a food theme — the bigger group of three wins.
- Ignoring the second lens. If nothing links by meaning, immediately test spelling, sounds and hidden words before guessing.
Marking these at home is valuable coaching: a wrong answer usually tells you which lens your child forgot to try. That diagnostic habit is exactly what our revision hub is built around.
Timing and pacing on the real paper
GL Verbal Reasoning papers are tightly timed at roughly 50 minutes, so every question needs a budget. Odd-one-out is one of the quicker types once the categories are known, which means it is a good place to bank time for slower types like letter codes.
| Element | Guide |
|---|---|
| Target time per odd-one-out | ~30–40 seconds |
| Method | read all five, name the category, find the outsiders |
| If stuck after 40 seconds | mark it, move on, return at the end |
| Second lens if meaning fails | syllables, silent letters, hidden words |
A timed run against the clock builds this instinct fastest. Try a free mock paper, or a centre-matched exam from our centre-specific mocks, to see how odd-one-out sits alongside the other 20 GL types.
How odd-one-out lifts the Standardised Age Score
GL marking converts raw scores into a Standardised Age Score (SAS), age-adjusted by your child's exact age in months so younger pupils are not disadvantaged. The scale runs roughly from 69 to 141, with 100 as the national average, and many grammar schools look for around 111 or higher — though exact pass marks vary by area and year, so never rely on a fixed number. Because odd-one-out is a fast, high-accuracy type, getting these right protects easy marks and lifts the SAS, freeing focus for the trickier questions.
Building the vocabulary that powers it
Odd-one-out rewards a broad, well-sorted vocabulary. The little-and-often approach beats cramming: five minutes of flashcards a day, sorting words into categories, and reading widely so unfamiliar words become familiar. Pair that habit with the wider Verbal Reasoning family — see our guide to the exam guides and the full toolkit on the GL 11+ papers page.
Frequently asked questions
Is odd-one-out always about meaning?
No. Most questions group by meaning, but harder ones group by letters, syllables, silent letters or hidden words. If meaning does not fit, switch to the "letters lens" straight away.
How many words do I choose?
Two. Three of the five words share a connection; the two that do not belong are the answer. Circling the matching group instead of the odd pair is the most common mistake.
How long should each question take?
Aim for about 30 to 40 seconds. GL papers run roughly a minute per question overall, and odd-one-out is one of the faster types, so it is a good place to save time for slower questions.
