Questions & Answers about Мы переизбрали председателя.
Мы means we.
In Russian, subject pronouns are often omitted when the verb ending already makes the subject clear. So Переизбрали председателя can also mean We reelected the chairperson/chairman, depending on context.
Including мы makes the subject explicit. It can sound more natural if you want to emphasize we specifically.
The ending -ли shows past tense plural.
So:
- переизбрал = he reelected
- переизбрала = she reelected
- переизбрало = it reelected
- переизбрали = they reelected / we reelected / you plural reelected
Russian past tense does not mark person, only gender in the singular and number in the plural. The subject мы tells you this means we reelected.
The infinitive is переизбрать, meaning to reelect.
This verb is built from:
- избрать = to elect
- prefix пере- = again, re-
So переизбрать literally means to elect again.
