~ば (ba)if (conditional)
Used to express a conditional relationship where the second clause is a result of the first. Verbs are formed by changing the final 'u' sound to 'e' and adding 'ba'. For i-adjectives, drop 'i' and add 'kereba'.
Common mistakes
- Confusing with ~たら for one-time past events
- Incorrectly using the dictionary form before 'ba'
- Using it for requests or invitations (use ~たら instead)
