Mea culpa is pretty common and translate similarly in Brazil (minha culpa), after all, portuguese is a language that has latin as an ancestor, but my favorite and the one that confused me the most the first time I saw is "Quod erat demonstrandum", almost all mathematical proofs that I did in college had Q.E.D. instead of the portuguese C.Q.D. at the end to indicate that that was the point where the proof was finished.

Goddamnit, I always misspell it. Interesting; had never read about the origin of the term.

If it helps for the future, it's pronounced "mayuh coolpuh", so the e makes the "ay" sound.

The IPA is /me.a kul.pa/.

So that's a reasonable approximation. The vowels are off. If you know Spanish pronunciation, it's exactly the same for this word.

Specifically, The E sound is actually the single-vowel /e/, not the diphthong /aɪ/. The "uh" in both words is closer to "ah".

I fixed it for you. If you want it changed back, let me know.

Ut desint vires, tamen est laudanda voluntas.

The latin way to say "my bad"

miserere does sound much closer to misery than mercy. In English, it also "A medieval dagger, used for the mercy stroke to a wounded foe" ... That seems more like it.
