The One-Letter Move

Two ordinary words can hide a secret swap. Move just ONE letter, and both words change into new, real words. The trick is finding the letter that makes two answers work at once.

Picture each word as a row of letter tiles. You must lift one tile from one word, close the gap, then place that same tile into the other word. You may move the letter to the start, middle, or end. Now check both results. Each must be a correctly spelt, complete word. A tempting almost-word is not enough. And you cannot add a spare letter, lose a letter, swap two letters, or change one letter into another. Use a two-sided check. First, cover the letter where it began and read the shortened word aloud. Next, slide the tile through possible spaces in the other word. Stop only when BOTH sides are real words and every original tile is still used.

Let's work through an example. The question gives the words STONE and CAR. Move exactly one letter from one word to the other so that both results are valid words. Write the two new words. Start with STONE. Try removing the S. The letters left are T, O, N, E, which read TONE. That is a real word, so the first side passes. Now carry that exact S across to CAR. Test the open spaces. Put S before CAR, and you get SCAR. That is also a correctly spelt word. We moved one existing tile, used it once, and kept every other letter in order. So the explicit answer is TONE and SCAR. Check the pair together: STONE lost S to become TONE, while CAR gained that same S to become SCAR. Two real words. One moved letter.

Remember: take one existing letter, place it in the other word, then prove that both new spellings are real. Keep every letter accounted for, and you will crack these word moves with confidence! Slow down, test both sides, and trust your check.
