Questions & Answers about После вебинара я поеду домой на метро.
Because после requires the noun to be in the genitive case (“after what?”).
- вебинар (nominative) → вебинара (genitive singular)
So После вебинара = “After the webinar.”
Yes, вебинар is masculine. Common clues:
- It ends in a consonant (-р), which is typically masculine in Russian.
- In dictionaries it’s listed as вебинар, -а showing the genitive ending -а, typical for many masculine nouns.
Because поеду is the future form (perfective) meaning “I will go / I will ride (by transport).”
- я еду = “I’m going / I’m riding” (present, happening now)
- я поеду = “I will go (once, in the future)”
Russian often chooses a perfective verb for a single future trip.
