Hidden-word and compound-word questions look very different on the page, but they draw on the same underlying skill: scanning letters methodically rather than reading for meaning. Both appear regularly in GL Assessment Verbal Reasoning papers, and both feel baffling the first time a child meets them, then become almost mechanical once the search routine is drilled. This guide breaks down exactly how each type works, gives you worked examples you can copy at home, and shows where these two sit among the wider family of 11+ letter-manipulation questions.
Where these types fit in the GL Verbal Reasoning paper
GL Assessment is now the dominant 11+ provider across most English grammar-school regions, having largely absorbed the space left when CEM withdrew its separate 11+ tests around 2022-2023. A GL Verbal Reasoning paper is multiple-choice, answered on a separate answer sheet, tightly timed at roughly 35-50 seconds per question, and drawn from a bank of around 21 named question types. Crucially, GL does not tell you in advance which types will appear in a given year, so a well-prepared child needs a routine for every one of them. Bond's popular workbooks label these types with letters A to U, and both Hidden Words and Compound Words sit within that letter-manipulation cluster alongside Move a Letter, Insert a Letter, letter codes and anagrams. Our full 21 Verbal Reasoning question types guide maps the whole set; here we go deep on two of them.
Hidden words: the search routine
In a Hidden Word question, a four-letter (sometimes three-letter) real word is hidden across the boundary of two words in a sentence — it always sits partly at the end of one word and partly at the start of the next. The trap children fall into is scanning inside single words. The hidden word never lives inside one word; it always straddles the gap.
Take the sentence: We had a lovely picnic near the lake. The instruction is to find a four-letter word hidden between two adjacent words. Slide a four-letter window across the join of picnic and near: ...c-n-e-a? No. Try the join more carefully — take the last letters of one word and the first of the next: i-c-n-e, c-n-e-a, n-e-a-r. Now look at lovely picnic: the end of lovely and start of picnic gives l-y-p-i, y-p-i-c — no word. Keep going and the hidden word emerges cleanly from another join. The method matters more than any single answer: check each word-boundary in turn, sliding a fixed-length window straight across the space.
Teach your child three habits and Hidden Words stops being guesswork:
- Ignore whole words. The answer is never contained inside one word, so cross the gap every time.
- Count the required length exactly. If the question wants a four-letter word, only test four-letter runs — no more, no less.
- Say each candidate under your breath. Real words click; nonsense strings feel wrong. Trust the ear.
Compound words: joining two halves into one real word
A Compound Word question gives you two small groups of words. You must take one word from the first group and join it to one word from the second group so that together they spell a single real English word. There is always exactly one pairing that works, which is what makes the type reliable once you slow down.
For example, group one might offer car, sun, tea and group two pot, flower, road. Test combinations aloud: carpot (no), carflower (no), carroad (no), sunpot (no), sunflower — yes, a real word. The winning join here is sun + flower = sunflower, and teapot would also be real, so read every option before committing, because more than one pairing can look tempting until you check them all.
The efficient approach is to take each word from the first group and quickly run it against every word in the second, listening for the click of a genuine word rather than trying to reason it out on paper. Children who read the options aloud in their head are far faster than those who stare silently.
The wider letter-manipulation family
Hidden Words and Compound Words rarely appear alone. GL loves to mix in their close cousins, and children who can tell them apart lose far less time. Here is a quick reference to the letter-based types, each with a mini example.
| Type | What you do | Mini example |
|---|---|---|
| Hidden Word | Find a short real word straddling two adjacent words | ...pic near... hides a four-letter word across the join |
| Compound Word | Join one word from each group to make one real word | sun + flower = sunflower |
| Move a Letter | Remove one letter from word 1, add it to word 2 so both stay real | Move S from stable to tale: table + slate? Check both remain words |
| Insert a Letter | Find the letter that ends word 1 and starts word 2 | hea( ? )ield: T gives heat and tield? Test until both are real |
| Anagram / making words | Rearrange given letters into a new real word | LISTEN rearranges to SILENT |
The confusable pair to watch is Move a Letter versus Insert a Letter. In Move a Letter, both the shorter and the longer word must still be real English words after the move — so children must check both results, not just one. In Insert a Letter, the single letter you choose has to simultaneously complete the first word and begin the second. Slowing down to verify every resulting word is the single biggest accuracy gain on these types. If letter codes are also on your list, our guide to cracking 11+ letter codes walks through the alphabet-hop method step by step.
Vocabulary is the quiet engine
Every one of these types rewards a wide vocabulary. A child who knows slate, heath or sunflower spots the answer instantly; a child who does not will stall even with a perfect method. Build vocabulary little and often — five minutes a day beats an hour once a week. Flashcards of synonym and antonym pairs, a running word list from reading, and quick "how many compound words start with sun?" games at the dinner table all feed directly into Verbal Reasoning scores. This same vocabulary work lifts synonyms, antonyms, odd-one-out and analogy questions too, so it is the highest-value habit you can build. Our revision hub gathers word lists and short daily drills you can print.
Timing and how scores are worked out
Because a GL paper allows only about 35-50 seconds per question, a slow-but-correct child can still miss the mark. Practise with a timer so the search routine becomes automatic. If a Hidden Word or Compound Word will not surface within about 30 seconds, mark it, move on, and return at the end — never let one puzzle swallow the time budget for five others.
| Paper feature | Typical figure |
|---|---|
| Paper length | about 50 minutes |
| Time per question | roughly 35-50 seconds |
| Marking | Standardised Age Score (SAS) |
| SAS range | roughly 69-141, 100 = average |
Raw marks are converted to a Standardised Age Score that adjusts for a child's exact age in months, so a summer-born pupil is not disadvantaged against an older classmate. Many grammar schools look for around 111 or above, but exact pass marks vary by area and year, so treat any single number as a guide rather than a promise. Getting the trickier letter-manipulation types right lifts the raw score, which in turn lifts the SAS — a useful way to explain to children why precision on these questions genuinely matters. To rehearse under real conditions, build up through our free worksheets and then sit a timed mock paper, or find a paper matched to your target school on the centre-specific mocks page.
Common mistakes to avoid
- Searching inside single words for a hidden word — it always crosses the gap between two words.
- Testing the wrong length — a four-letter hidden word means exactly four letters, not three or five.
- Stopping at the first plausible compound — read every pairing, because a second real word may be the intended answer.
- Forgetting to check both words in Move a Letter — both the shorter and longer results must be real.
- Reading silently — saying candidates in your head is much faster than reasoning them out on paper.
Frequently asked questions
Does the hidden word always cross between two words?
Yes. In GL-style Hidden Word questions the answer is never contained inside a single word — it always sits partly at the end of one word and partly at the start of the next. Teaching your child to scan across the gaps, ignoring whole words, removes most of the difficulty.
Can more than one compound word be possible?
The question is designed so that only one pairing makes a genuine real word, but decoy combinations often look tempting. That is why your child should test every option from both groups before choosing, rather than grabbing the first join that seems to work.
How much time should each of these questions take?
Aim for well under a minute — around 35-50 seconds — to stay on pace across a roughly 50-minute paper. If an answer will not appear in about 30 seconds, mark it, move on, and return at the end so a single puzzle never costs you several easier marks.
