Odd Two Out flips the usual instinct on its head. Your child is given five words and has to find the two that do not belong, which means the real work is spotting the three that share a hidden link. The clever twist is that the two odd words do not need anything in common with each other; they are simply the leftovers once the group of three is found.
This question type lives in the GL Assessment 11+ Verbal Reasoning paper, a fast test of about 80 questions in roughly 50 to 60 minutes, organised into blocks by type with answers marked on a separate answer sheet. Finding two odd words rather than one makes this a step harder than a classic odd-one-out, and GL knows it. Our research estimate from analysing practice papers is that it appears as a block of perhaps 4 to 8 questions, though GL does not publish the figure.
On this page your child practises the genuine select-two format, with a worked explanation that names the connecting link as exactly as possible after every question. Learning to say "trees, not just plants" or "racquet sports, not just sports" is the heart of this skill, and the explanations train that precision one question at a time.
The hidden link in an Odd Two Out question can be drawn from many kinds of category. GL publishes no weighting, so the following is our research estimate, ordered roughly from most to least common:
Difficulty climbs from clearly different everyday categories at the easy end to advanced vocabulary, narrow sub-categories and double-meaning traps at the hard end, where all five words appear to belong to one broad group and only a sharper, more specific link separates the three.
These four question types all turn on what words mean, but they ask for different things. Synonyms want a word that matches, antonyms want its opposite, analogies want you to copy a relationship onto a new pair, and odd two out wants the two words that break a hidden group of three.
| Question type | What it tests | What it looks like | The classic mix-up |
|---|---|---|---|
| Odd Two OutThis page | Whether your child can spot three words that share a link and the two that do not belong. | Five words; your child marks the two that fall outside the group the other three form. For example: "oak, rose, pine, birch, tulip". | Treating it like synonyms and matching two similar words, instead of finding the group of three and leaving the outsiders. |
| Synonyms | Whether your child knows a word that means the same, or nearly the same, as a given word. | Two small groups of words; your child finds the pair, one from each group, that mean almost the same. For example: "(rapid, gentle, loud) (soft, swift, bright)". | Slipping into antonym mode and hunting for the opposite, so "swift" is matched with "slow" rather than a same-meaning word. |
| Antonyms | Whether your child can find a word that means the opposite of a given word. | Two small groups of words; your child picks the pair, one from each, that are opposites. For example: "(ancient, brave, narrow) (calm, wide, gentle)". | Grabbing a same-meaning word by mistake, so "narrow" is paired with "thin" instead of its opposite "wide". |
| Verbal Analogies | Whether your child can spot the relationship in one word pair and copy it onto a second. | A sentence in the shape "A is to B as C is to ?". For example: "calf is to cow as foal is to ___", where the answer is horse. | Treating it like odd two out and hunting for the word that does not fit, rather than copying the relationship. |
If the question gives you one target word and asks for a single match, it is synonyms or antonyms; if it gives you a completed pair to imitate, it is an analogy; if it gives you five words and asks which do not fit, it is odd two out.

Find the two words that are the odd ones out.
Select the two correct answers.
Hamster, rabbit, and guinea pig are furry pets you can hold. Goldfish and trout are both fish, so they are the odd ones out. Tip: If all five seem to belong to one group, look for a more SPECIFIC sub-category that only three share. ✓
Find the two words that are the odd ones out.
Select the two correct answers.
Whisper, shout, and announce all involve speaking or making a sound. Listen and hear both involve receiving sound, so they are the odd ones out. Tip: Name the link specifically. 'All trees' is better than 'all nature things'. ✓
Find the two words that are the odd ones out.
Select the two correct answers.
Foal, stallion, and mare are all types of horse (young, male adult, female adult). Calf (young cow) and lamb (young sheep) are baby animals of different species, so they are the odd ones out. Tip: If all five seem to belong to one group, look for a more SPECIFIC sub-category that only three share. ✓
Find the two words that are the odd ones out.
Select the two correct answers.
Serene, tranquil, and placid all mean calm and peaceful. Furious and irate both mean very angry, so they are the odd ones out. Tip: Name the link specifically. 'All trees' is better than 'all nature things'. ✓
Find the two words that are the odd ones out.
Select the two correct answers.
Tennis, badminton, and squash are all racquet sports. Chess and draughts are board games, so they are the odd ones out. Tip: Go specific, not broad. If all five are animals, what kind of animal are exactly three of them? ✓
Common mistake 1 of 4
Hunting for the two odd words instead of the group of three.
Tip: It is far easier to find what links three words than to spot two unrelated leftovers. Teach your child to ask "which three clearly belong together?" and let the odd two fall out naturally.
Common mistake 2 of 4
Settling for a link that is too broad.
Tip: If all five words fit a wide group such as "animals" or "furniture", the answer needs a tighter link. Encourage your child to name the connection as precisely as possible, for example "furniture for sitting" rather than just "furniture".
Common mistake 3 of 4
Assuming the two odd words must relate to each other.
Tip: GL builds questions where the leftovers have nothing in common, which makes children doubt a correct answer. Remind your child that the odd two are simply whatever is left once the group of three is settled.
Common mistake 4 of 4
Being caught by a word with two meanings.
Tip: In harder questions a homonym can seem to fit the wrong group, such as lamb as a young animal or as meat. Teach your child to test both meanings of a tricky word before deciding which group it belongs to.

It is a question that gives your child five words and asks them to find the two that do not belong. The other three share a specific link, and the two odd words are simply the leftovers. It tests vocabulary, category knowledge and careful reasoning all at once.
Your child reads the five words and selects the two odd ones out, marking them on a separate answer sheet. The challenge comes from GL choosing words where the connecting link is specific rather than obvious, so a child has to look past the first broad category they notice.
GL does not publish the exact count. Our research estimate from practice papers is roughly 4 to 8 Odd Two Out questions in a typical Verbal Reasoning paper of about 80 questions, usually grouped together as one block.
The questions where all five words seem to belong to one broad group, so your child must find a sharper, more specific link that only three of them share. Advanced vocabulary and words with double meanings make these the most demanding, because the obvious grouping is often a deliberate red herring.
The key habit is to look for the three that link rather than the two that are odd, and to name that link as precisely as they can. Building general knowledge of categories such as trees, instruments and sports also helps. Free PrepStep practice gives one Odd Two Out question at a time with a worked explanation that names the exact link, so your child sharpens that precision steadily.
They all rest on word meaning but ask different things. Synonyms want a word meaning the same, antonyms want its opposite, and both give you two small word groups to pick a matching pair from. Verbal analogies give you a completed pair, such as "A is to B as C is to ?", and ask you to copy that relationship. Odd two out gives five words and asks which two fall outside the group the other three share.
