Questions & Answers about Наш поезд задержался из-за тумана.
Why is it наш and not наша or наше?
Because наш has to agree with поезд.
- поезд = a masculine singular noun
- in this sentence, it is the subject, so it is in the nominative case
So the correct form is:
- наш поезд = our train
Compare:
- наш поезд = our train
- наша машина = our car
- наше такси = our taxi
- наши поезда = our trains
Why is задержался in that form?
Russian past-tense verbs agree with the subject in gender and number.
The subject here is поезд, which is:
- masculine
- singular
So the past-tense form is:
- задержался = masculine singular past
Compare:
- поезд задержался = the train was delayed
- электричка задержалась = the commuter train was delayed
- такси задержалось = the taxi was delayed
- поезда задержались = the trains were delayed
