President Donald Trump used Twitter to wish Irish people around the world a happy St. Patrick’s Day in Irish Gaelic.

But there was a slight problem with his well-intentioned Friday morning tweet in that he misspelled one of the words. Instead of correctly translating St. Patrick’s Day as “Lá Fhéile Pádraig,” he erroneously posted “Lá Fheile Phadraig.”

Happy Lá Fheile Phadraig to all of my great Irish friends! — Donald J. Trump (@realDonaldTrump) March 17, 2017

Twitter users immediately spotted the additional “h” in the third word and delightedly pointed it out (some more savagely than others).

Really? @realDonaldTrump - "Lá fhéile Pádraig sona dhuit" is correct. But then why start now? — Kathleen Obrahalahan (@obrah318) March 17, 2017

@realDonaldTrump You spelt it wrong...'Lá Fhéile Pádraig'

@realDonaldTrump Slight correction: It's "Lá Fhéile Pádraig." You don't need a séimhiú on "Pádraig," and you forgot the fada. — William Brennan (@wm_brennan) March 17, 2017

It’s the latest St. Patrick’s Day-linked gaffe from Trump and his administration.

At Thursday’s Friends Of Ireland luncheon in Washington D.C., Trump was widely ridiculed for reciting a proverb for his “Irish friends” ― which turned out to probably not be Irish at all ― and House Speaker Paul Ryan (R-Wis.) held up a lackluster pint of Guinness and got seriously dragged on Twitter.

Team Trump’s green St. Patrick’s Day edition of its “Make America Great Again” hats were also found to feature a four-leaf clover, instead of the shamrock associated with the day, stitched on the back.
