There are six basic tenses:
Present "John eats/is eating/does eat Chinese food"
Imperfect "John was eating/used to eat Chinese food"
Future "John will eat/is going to eat Chinese food"
Perfect "John ate/has eaten Chinese food"
Pluperfect "John had eaten Chinese food"
Future perfect "John will have eaten Chinese food"
Those are all active but can be put into passive - "Chinese food will have been eaten by John", etc.
The last three are super easy to form, but the first three require a bit of memorization. (which vowel goes where! which ending to use!) There are four conjugations into which most verbs fall - you conjugate the verbs from 1st conjugation one way and 2nd conjugation another, etc.
I imagine verbs as little children while learning them. If they're not messy and always nicely behaved, how interesting could it be? So grin, bite your lower lip, and make some flashcards
And then there's the subjunctive! Used for things like "Let's go" or "I wish he'd come", etc. I don't know that yet, so I can't speak about its difficulty.
In first declension, watch out for filia, -ae, f. (daughter) Its declension is
Because the second declension word filius, -i, m. would have the same dative and ablative plural endings if filia were regular. -abus makes a distinction.
That is the only one I can think of though, besides words for occupations (poetae, nautae) being masculine
Good luck self-studying! Beginning is the hardest part.
