gif

Etymology: From Proto-Germanic jabai (when, if) with anomalous apocope. The expected form is attested once as ġyfe in the early 7th-century Law of Æthelberht, if not simply a scribal error.

Conjunction: ġif

Descendants: Middle English: if, yif, yef

Therefore, “gif” is pronounced with a Y

Edit: Yes, this was a very long way to go for a furry joke
