* Rule 3: If a word starts with a consonant sound followed by "qu", move it to the end of the word, and then add an "ay" sound to the end of the word (e.g. "square" -> "aresquay").
* Rule 4: If a word contains a "y" after a consonant cluster or as the second letter in a two letter word it makes a vowel sound (e.g. "rhythm" -> "ythmrhay", "my" -> "ymay").
*
* Regel 1: Wenn ein Wort mit einem Vokal beginnt, fügen Sie am Ende des Wortes ein „ay“ hinzu. (a, e, i, o, u)
* Bitte beachten Sie, dass „xr“ und „yt“ am Anfang eines Wortes Vokale erzeugen (z. B. „xray“ -> „xrayay“, „yttria“ -> „yttriaay“).
* Regel 2: Wenn ein Wort mit einem Konsonanten beginnt, verschieben Sie es an das Ende des Wortes und fügen Sie dann einen „ay“-Laut am Ende des Wortes hinzu.
* Konsonantenlaute können aus mehreren Konsonanten bestehen, auch bekannt als Konsonantencluster (z. B. „Stuhl“ -> „airchay“).
* Regel 3: Wenn ein Wort mit einem Konsonanten beginnt, gefolgt von „qu“, verschieben Sie es an das Ende des Wortes und fügen Sie dann einen „ay“-Laut an das Ende des Wortes an (z. B. „Quadrat“ -> „aresquay ").
* Regel 4: Wenn ein Wort ein „y“ nach einer Konsonantengruppe oder als zweiten Buchstaben in einem Wort mit zwei Buchstaben enthält, erzeugt es einen Vokal (z. B. „rhythm“ -> „ythmrhay“, „my“ -> „ymay“) ).
*
*
*
* There are a few more rules for edge cases, and there are regional variants too.
*
* See http://en.wikipedia.org/wiki/Pig_latin for more details.
