Grammar Rule in 30 Seconds
The Perfekt tense uses the present tense of 'biti' plus an l-participle to describe completed actions in the past.
- Use the present tense of 'biti' (sam, si, je, smo, ste, su) for the auxiliary.
- Add the l-participle of the main verb (e.g., radio, radila, radilo).
- The l-participle must agree in gender and number with the subject.
