kob

1. formal fate; doom
   Zla kob pratila je tu porodicu godinama. — An evil fate haunted that family for years.
   Takva je, izgleda, bila njegova kob. — That, it seems, was his fate.
2. formal dated omen; portent
   Starci su u tom snu videli zlu kob. — The old people saw a bad omen in that dream.

The word is mostly bookish; the adjective «koban» 'fateful, fatal' is more common in speech. In the sense 'omen' it is dated: today people say loš predznak or loše znamenje.
