Semelfactive Verbs (Jednokratni glagoli)
Grammar Rule in 30 Seconds
Semelfactive verbs describe a single, instantaneous action that happens once and is completed immediately.
- Use them for actions that cannot be repeated quickly, like 'to sneeze' (kihnuti).
- They are always perfective, meaning they focus on the completion of the single event.
- They often use the suffix -nu- to indicate the 'one-time' nature of the action.
