Here are two important rules for you to remember:
- (1) the thematic vowel in third conjugation is a short vowel; it appears as -i- or -u- in the present and -e- in the imperfect
- (2) The tense sign for the future in third conjugation is -e-; the future tense in third conjugation uses no thematic vowel
Luckily, the formation of the present tense in third conjugation follows a pattern similar to that seen in first and second conjugation.
- Take a third-conjugation verb base
- add a thematic vowel (Which will be fairly irregular in this conjugation)
- and to that, append personal endings.
