Verb ‘to be’ or ‘biti’ in Serbian is an irregular verb – like in most languages. In this lesson you’ll learn its singular forms:

 

ja sam (I am)

ti si (you are)

on je (he is)

ona je (she is)

 

To make it negative, we simply add ni- in front of the verbal forms:

ja nisam (I’m not)

ti nisi (you’re not)

on nije (he’s not)

ona nije (she’s not)
