# Pig Latin
|
||
|
|
|
||
|
|
Welcome to Pig Latin on Exercism's Elixir Track.
|
||
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||
|
|
|
||
|
|
## Introduction
|
||
|
|
|
||
|
|
Your parents have challenged you and your sibling to a game of two-on-two basketball.
|
||
|
|
Confident they'll win, they let you score the first couple of points, but then start taking over the game.
|
||
|
|
Needing a little boost, you start speaking in [Pig Latin][pig-latin], which is a made-up children's language that's difficult for non-children to understand.
|
||
|
|
This will give you the edge to prevail over your parents!

## Instructions
|
||
|
|
|
||
|
|
Your task is to translate text from English to Pig Latin.
|
||
|
|
The translation is defined using four rules, which 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 a 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"` -> `"ay"` (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"`)
