Interesting comment. Do you mean trouble with using English correctly, or trouble with grammatical analysis or terminology?

Mainly grammatical analysis, but that helps some more pedantic parts of very formal English.

I’ve only be learning for a year or so — will the mapping of tenses from Latin to English ever make sense?

I've never had much of a problem with that, Latin tenses have the perfect vs imperfect which maps pretty well to the ING ending in English and then past/present/future which maps well

One issue is that sometimes what's easy to say on Latin is a bit of a mouthful to say in English in a literal translation. But that's more of a, well you wouldn't express that thought the same way in English.
