①Present — full: jesam, jesi, jest, jesmo, jeste, jesu. (Stressed; answers “da li” questions.)
②Present — short clitics: sam, si, je, smo, ste, su. (The everyday forms: ja sam, on je.)
③Conditional: bih, bi, bi, bismo, biste, bi — “I would be”, ja bih.
④Present II (budem-form): budem, budeš, bude, budemo, budete, budu — used after da / ako and in the future perfect (da budem, budem radio).
⑤Past participle: bio (m), bila (f), bilo (n), bili / bile / bila (pl) — agrees in gender & number (bio sam, bila sam).
3sg trap: the full form is jest, the clitic is je. 3pl of both presents is -su / jesu.
