Questions & Answers about Ako ne vidiš ulaz, pozovi me telefonom.
Ako means if. It introduces a condition:
- Ako ne vidiš ulaz... = If you don’t see the entrance...
This is the normal Serbian word for if in everyday conditional sentences.
Serbian commonly uses the present tense after ako when talking about a real future possibility, just like English often does:
- Ako dođe, javi mi. = If he comes, let me know.
- Ako ne vidiš ulaz, pozovi me telefonom. = If you don’t see the entrance, call me by phone.
So even though the whole situation may be in the future, vidiš stays in the present tense.
Vidiš is the 2nd person singular present form of videti / vidjeti (to see).
So:
- ja vidim = I see
- ti vidiš = you see
- on/ona vidi = he/she sees
Because the sentence is speaking to you singular, Serbian uses vidiš.
