Grammar Rule in 30 Seconds
Latvian prefixes turn ongoing actions into completed ones, changing the verb's aspect from imperfective to perfective.
- Add a prefix to an imperfective verb to show completion: 'lasīt' (to read) -> 'izlasīt' (to finish reading).
- Prefixes often change the meaning slightly, like 'iet' (to go) -> 'aiziet' (to leave/go away).
- Perfective verbs cannot be used in the present tense to describe ongoing actions; they imply future completion.
