Questions & Answers about Ja sam juče našla ključ u torbi.
Sam is the 1st person singular present form of biti (to be), and Serbian uses it to form the past tense.
So the past tense here is built like this:
- sam = auxiliary am
- našla = past active participle of naći (to find)
Together:
- ja sam našla = I found
This is a very common Serbian past-tense pattern:
- ja sam rekla = I said
- ja sam videla = I saw
- ja sam kupila = I bought
Because našla shows that the speaker is female.
In Serbian past tense, the participle agrees with the subject’s gender and number:
- našao = masculine singular
- našla = feminine singular
- našlo = neuter singular
- našli / našle = plural
So:
- a woman says: Ja sam juče našla ključ u torbi.
- a man says: Ja sam juče našao ključ u torbi.
This is one of the big differences from English: Serbian past tense often tells you the speaker’s gender.
