Ego Odium Latin Lingua

I'm sure the title's wrong.

It rarely fails, given that I read more than I talk, that I can manage to make an ass of myself stumbling over the pronunciation of a word that I am quite familiar with, but don't particularly know how to pronounce.

Latin words are the worst for me.

Today's offender was a posteriori.

It sucks because in System Identification literature, a priori and a posteriori are not just Latin rhetorical flourishes, but technical terms.

Tell me I'm not alone.
