How to Answer 11+ Letter Fit Questions

A letter fit question shows you two pairs of word-pieces with a gap in each: "te [?] ap ope [?] ame". One single letter fills both gaps. It has a double job each time: it must FINISH the word in front of it and START the word after it. Here the letter is n — it turns "te" into TEN and begins NAP, and it turns "ope" into OPEN and begins NAME. One letter, four words.

That's the whole puzzle: five letters to choose from, and only one of them completes all four words.

Children usually like this type because it's quick — but that speed is exactly the danger. A letter that fixes the FIRST pair beautifully can fail the second pair, and a rushing child never checks. The method below is built around one habit: test every job the letter has to do.

The method

1. Start with the first pair. Say the front piece out loud with each option letter stuck on the end: "tet… ted… ten…". Real words announce themselves when you hear them.
2. Make the letter do its second job. Found a real word? Now check the same letter STARTS the piece after the gap: n + ap = nap. If it doesn't, that letter is out — however good it sounded.
3. Now test the second pair with your survivor. The same letter must finish the third word and start the fourth: ope + n = open, n + ame = name. Only when all four words are real are you done.
4. If you're stuck, cross out instead. Run each option through pair one and bin every letter that fails. Usually only one or two survive to be tested on pair two — that's much faster than dithering.

Worked examples

Example 1

Find the letter that fits into both pairs of brackets: te [?] ap ope [?] ame

A. t B. d C. n D. m E. s

1. Pair one, ends first: tet? no. ted? Ted is a name, not a word — wobbly. ten? Yes.
2. Second job: n + ap = nap. Both real.
3. Pair two: ope + n = open, n + ame = name. Four real words.

Answer: C. n — ten, nap, open, name.

Example 2

Find the letter that fits into both pairs of brackets: wit [?] ill brus [?] ouse

A. h B. t C. d D. n E. r

1. Try h on pair one: wit + h = with, h + ill = hill. Strong start.
2. Don't stop there — pair two is the real test: brus + h = brush, h + ouse = house.
3. All four are real words. (Notice t fails immediately: "witt" isn't a word.)

Answer: A. h — with, hill, brush, house.

Example 3 (harder — an unusual letter)

Find the letter that fits into both pairs of brackets: hoa [?] enon sphin [?] ylophone

A. r B. t C. x D. d E. s

1. Cross out with pair one: hoar is a word, but r + enon is nothing. hoat, hoad — no. hoax? Yes: x.
2. Second job: x + enon = xenon (a gas — and one of the few words that starts with x).
3. Pair two seals it: sphin + x = sphinx, x + ylophone = xylophone.

Answer: C. x — hoax, xenon, sphinx, xylophone.

The traps

• The half-fit. The letter that nails pair one and quietly fails pair two. This is the trap the whole type is built on — the second pair exists to catch people who stop checking early.
• Forgetting the double job. Every gap is two jobs: end a word, start a word. A letter that makes "belt" but can't start the next piece is a wrong answer, however real "belt" is.
• Trusting sound over spelling. Some finishes are silent or odd on the page: the b in "limb", the h in "myth". Picture the written word, not just the sound of it.
• Fearing rare letters. X, y and e all turn up as answers. If the ordinary letters keep failing, stop re-trying them and give the strange ones their turn.
