Verbs in the past tense are conjugated by changing the end of the word.
Verbs in the present tense are conjugated by changing the beginning and the end of the word.
Except from the normal form of present tense, there are two other forms called subjunctive and jussive.
The subjunctive (also known as the imperfect subjunctive) is used after the particles that and will not.
The jussive is used after the particle lam to negate past tense.
The imperative is used for commands and requests.
