I’m Irish. I’m also Portuguese, French, German, English, Dutch, and Scottish. But because of that little slice of Irish, I especially like St. Patrick’s Day. My daughters are older now (one is in college), but I still got my 16-year-old Lucky Charms today so she could have an extra sugary breakfast to celebrate. It’s the only day of the year I ever buy sugary cereal—I’m one of those moms. I’m also an editor mom, so before she hopped into her car to drive herself to school, I felt it my duty to call out, “Be sure to spell St. Paddy’s with two D’s and not two T’s!”

If you’re planning to abbreviate St. Patrick’s Day, make sure you say “St. Paddy’s Day,” not “St. Patty’s Day.”

Why Paddy, Not Patty?

The confusion often stems from the name “Patrick.” In English, “Patrick” seems to lend itself to “Patty” as a natural shorthand. But in Ireland, St. Patrick’s name derives from the Irish name Pádraig (pronounced “Paw-rig”). The correct diminutive form of Pádraig is Paddy.

“Patty” is typically a nickname for “Patricia.” It also conjures up images of burger patties, and while burgers are great, especially when topped with roasted mushrooms and blue cheese, they have nothing to do with Ireland’s most celebrated saint.

The Bottom Line

St. Patrick’s Day is a celebration of Irish culture, history, and community. Whether you’re Irish by blood or just Irish for the day, remembering to say St. Paddy’s Day (not Patty’s) is a great way to show your respect—and avoid a friendly lecture from an Irish person or an editor…or an Irish editor!

This March 17th, deck yourself in green, enjoy the festivities, and remember: Paddy, not Patty. Sláinte!

Extra tip: In case you’re wondering, this is the correct spelling of leprechaun. They are a doozy to catch and to spell.
