It’s an age-old conundrum…. and it drives me crazy.  I’ve seen way too many St. Patty Day postings, signs, even events.  It’s St. Paddy’s Day if you shorten it!

Paddy is derived from the Irish, Pádraig: the source of those mysterious, emerald double-Ds.

Patty is the diminutive of Patricia, or a burger, and just not something you call a fella.

There isn’t a sinner in Ireland that would refer to a Patrick as “Patty”. It’s as simple as that.
