Questions & Answers about Мы решили отложить поездку на дачу, потому что обещают сильный ветер.
Решили is the past tense plural form of решить (to decide).
- мы решили = we decided
- Russian past tense agrees with the subject in gender/number:
- я решил = I decided (male speaker)
- я решила = I decided (female speaker)
- мы решили = we decided
The verb решить is perfective, so it presents the decision as a completed act: they reached a decision.
This is about aspect.
- отложить = perfective → to postpone once, as a completed decision/action
- откладывать = imperfective → to be postponing, to postpone repeatedly, or to speak about the process in a general way
After решили (decided), Russian very often uses a perfective infinitive if the decision is about doing a single complete action:
- Мы решили отложить поездку. = We decided to postpone the trip.
If you used откладывать, it would sound more like deciding on an ongoing or repeated behavior, which is not the main idea here.
