fakat

1. colloq. fact
   To je fakat, niko ne može da ga porekne. — That's a fact, nobody can deny it.

2. colloq. Croat. really; indeed
   Fakat? Nisam to znao. — Really? I didn't know that.
   Fakat si ovo dobro uradio. — You really did a good job on this.

In the sense 'really, indeed' the word is typical of Croatia and Bosnia; in Serbia: stvarno, ozbiljno. In neutral speech the noun is usually replaced by «činjenica».
