Common Mistakes

Redundancy. In Croatian, the perfective aspect already implies completion.

Wrong: Jučer sam čitao knjigu i pročitao sam je.
Correct: Jučer sam pročitao knjigu.

If you intend to finish the letter, use the perfective 'napisati'.

Wrong: Sutra ću pisati pismo.
Correct: Sutra ću napisati pismo.

Habitual actions require imperfective verbs.

Wrong: Svaki dan sam pročitao novine.
Correct: Svaki dan sam čitao novine.

Common Questions (6)

No, perfective present is for the future.
Because Croatian distinguishes between process and result.
Ask if the action is finished or ongoing.
No. Even with a prefix, a perfective verb like pročitati cannot be used with duration markers like tri sata. You must use the imperfective čitati.
In some dialects and in older literature, the 'i' is kept. However, in standard modern Croatian, the 'i' is dropped in writing when the clitic follows.
Two verbs, one imperfective and one perfective, that share the same meaning.
