Finishing a Task

Review Summary

  • Prefix + Verb = Completed Action

よくある間違い

Using the base verb implies an ongoing process; adding the prefix 'pa-' is necessary to signal completion.

Wrong: Aš rašiau laišką (I was writing the letter - implies unfinished).
正解: Aš parašiau laišką (I wrote/finished the letter).

Perfective verbs describe a one-time completed event, not habits.

Wrong: Aš suvalgiau (I ate - using perfective for a general, habitual action).
正解: Aš valgydavau (I used to eat - habitual).

The prefix 'iš-' implies exiting or thoroughness, while 'pa-' is the standard for completion in this context.

Wrong: Aš išrašiau laišką (I finished writing the letter - wrong prefix).
正解: Aš parašiau laišką (I finished writing the letter).
