Accidental Meaning
Grammar Rule in 30 Seconds
Use the 'ter-' prefix to show an action happened by accident or without human intent.
- Add 'ter-' to a root verb to indicate an accidental occurrence: 'terjatuh' (fell down accidentally).
- Use it to describe a state resulting from an action: 'terbuka' (is open/was opened).
- It often replaces the subject-focused 'me-' prefix to remove the actor's agency.
