Spell That Sound
English gives most sounds several possible spellings and no dependable way to choose between them. Here you are given a sound — the long “ay”, the long “ee”, a plain “k” or “f”, the “shun” ending — and a word with a gap in it, and you pick the spelling that belongs in that particular word.
Each option is drawn as the finished word rather than a bare cluster of letters, so you judge it the way you would while reading rather than as a puzzle. Ten questions, an explanation after every one, and the blank fills itself in once you have answered. Ingglish’s answer to all of this is to give each sound exactly one spelling; see how English chooses instead.
