ER 23 Present, Future, or Perfect?

When trying to determine a verb's tense, ask yourself these questions, in this order.

1. Does it have an ending that is only used for one tense? (e.g., -bam, -bās, -bat for imperfect, -bō, -bis, -bit for future)

2. Is it formed from the present stem or perfect stem? If perfect, it's perfect tense. If present, it's present or future.

3. If it has an -e-, what conjugation is it? If 2nd conj, it's present. If 3rd, 3rd -iō, or 4th conj, it's future.
