"coda" means tail in Italian/Latin. In that sense, it's perfectly proper an maeningful. After all, as an Anglo-centric, there's no problem your using English in your musical terms. But music is an international 'language', so it's got to be in SOMEone's, to be understood universally. Just learn it! You're on here because you adapted to Bill Gates' / Steve Job's imposing their terminology on you, which you learned (and, I sorta guess, derived SOME benefit from, or why are you here?), so just apply the same to the folks of long ago who were fine with using Italian as a lingua franca.
