Basically, the Pig Latin system used here works as follows:

You take the first letter of a word (e.g. Hello = H) and use the last letters (e.g. Hello = ello) and add 'ay' to the first letter (e.g. Hello = Ello hay).

• Words that start with a vowel (A, E, I, O, U) simply have "ay" appended to the end of the word. Examples are:
• "eat" → "eatay"
• "omelet" → "omeletay"
• "are" → "areay"

• Words that start with a consonant have all consonant letters up to the first vowel moved to the end of the word (as opposed to just the first consonant letter), and "-ay" is appended. -('Y' is counted as a vowel in this context). Examples are:
• "pig" → "ig-pay"
• "banana" → "anana-bay"
• "trash" → "ash-tray"
• "happy" → "appy-hay"
• "duck" → "uck-day"
• "glove" → "ove-glay"
