Questions & Answers about Tavaly kezdődött a tanfolyam.
Tavaly means last year.
It is a complete time adverb by itself, so you do not need any extra word or ending with it. It refers to the previous year relative to the time you are talking from.
A useful contrast:
- tavaly = last year
- egy éve = a year ago / for a year
So Tavaly kezdődött a tanfolyam means the course began in the previous year, not necessarily exactly one year ago.
The dictionary form is kezdődik, which means to begin / to start.
So:
- kezdődik = begins / is beginning
- kezdődött = began / started
It is not a passive form. Hungarian usually does not express this idea with a passive the way English sometimes can. Instead, Hungarian uses an intransitive verb here: the course itself began.
