look at the pattern of vowels and consonants at the beginning of a word. +These rules look at each word's use of vowels and consonants: + +- vowels: the letters `a`, `e`, `i`, `o`, and `u` +- consonants: the other 21 letters of the English alphabet + +## Rule 1 + +If a word begins with a vowel, or starts with `"xr"` or `"yt"`, add an `"ay"` sound to the end of the word. + +For example: + +- `"apple"` -> `"appleay"` (starts with vowel) +- `"xray"` -> `"xrayay"` (starts with `"xr"`) +- `"yttria"` -> `"yttriaay"` (starts with `"yt"`) + +## Rule 2 + +If a word begins with one or more consonants, first move those consonants to the end of the word and then add an `"ay"` sound to the end of the word. + +For example: + +- `"pig"` -> `"igp"` -> `"igpay"` (starts with single consonant) +- `"chair"` -> `"airch"` -> `"airchay"` (starts with multiple consonants) +- `"thrush"` -> `"ushthr"` -> `"ushthray"` (starts with multiple consonants) + +## Rule 3 + +If a word starts with zero or more consonants followed by `"qu"`, first move those consonants (if any) and the `"qu"` part to the end of the word, and then add an `"ay"` sound to the end of the word. + +For example: + +- `"quick"` -> `"ickqu"` -> `"ickquay"` (starts with `"qu"`, no preceding consonants) +- `"square"` -> `"aresqu"` -> `"aresquay"` (starts with one consonant followed by `"qu`") + +## Rule 4 + +If a word starts with one or more consonants followed by `"y"`, first move the consonants preceding the `"y"`to the end of the word, and then add an `"ay"` sound to the end of the word. + +Some examples: + +- `"my"` -> `"ym"` -> `"ymay"` (starts with single consonant followed by `"y"`) +- `"rhythm"` -> `"ythmrh"` -> `"ythmrhay"` (starts with multiple consonants followed by `"y"`) diff --git
