Standard "pig Latin" transforms an English word by relocating all consonant sounds (if any) before the first vowel from the beginning to the end of the word, and then appending the sound to -ay. Examples include: run to unray; black to ackblay, mice to icemay, and act to actay. Pig Latin is intended to modify spoken English, so it should operate on pronunciations, not spellings. Thus: gem to emjay (or M.J.), hour to ouray, and wide to I'd weigh. Of special interest are words that become new English words or expressions in their pig-Latinized forms. Here are some of them.
