Grammar Rule in 30 Seconds
The 'ter-' prefix turns active verbs into stative or accidental passive forms, focusing on the result rather than the agent.
- Use 'ter-' to describe an accidental action: 'Terinjak' (accidentally stepped on).
- Use 'ter-' to describe a state or result: 'Tertutup' (is closed/shut).
- Use 'ter-' for superlative adjectives: 'Terbaik' (the best).
