Estonian verbs have just two tenses
A present and a past. Two more are made with a helper verb, the way English says “have done”. Mood, voice and person are separate switches on top, so you describe any form by saying how each switch is set.
- tenseaeg
- Two tenses the verb makes by itself, for now and before, and two more built with "to be", like "have done". There's no future among them.
- moodkõneviis
- Are you stating it, imagining it, telling someone to do it, or passing on something you only heard? School grammars count four moods, each with its own endings, and some reference books count five.
- voicetegumood
- Whether the sentence says who did it. It looks like the English passive but works differently, so keep the two apart.
- personpööre
- Six persons, each with its own verb ending, so "I" and "you" can often be left out. "He", "she" and "they" usually stay.
