Vowel sounds in English are many and various. There are only five vowels (a, e, i, o, u) but we make them work hard, squeezing lots of different sounds out of each. And that’s before we start on diphthongs. Here we explore the various spellings that are pronounced like the personal pronoun I (phonetically, ai). The story is nonsense, but it gives you as many possibilities as I could dream up.
