About Latin Tenses:
When you parse a Latin verb, you list the following:
A. meaning/translation
B. person
C. number
D. mood
E. voice (active/passive)
F. tense/aspect
Tense, as mentioned, refers to time. In Latin, there are 3 simple and 3 perfect tenses, a total of 6, and they come in both active and passive forms.
Moods In Different Tenses:
1. Present Tense:
The first of the simple tenses in the Indicative Mood is the present tense. The present tense in the Indicative Mood has both Active and Passive voices. The present tense shows action that is happening now.
- I walk - ambulo
2. Latin Imperfect Tense:
- I was walking - ambulabam
3. Latin Future Tense:
- He will walk - ambulabit
The 1st person singular future ambulabo is translated "I shall walk" -- technically. Most people in the U.S., if not in the rest of the anglophone world, would say "I will walk". The same is true of the 1st person plural ambulabimus: technically, it's "we shall walk," but in custom, it's "we will walk." In the second and third person, it's just "will" without qualification.
