~ばよかった (should have)
Meaning
A phrase which expresses the speaker's regret about not having done something or having done something undesirable. It means 'I should have...' or 'I wish I had...'
ばよかった combines the ば conditional form with よかった (past tense of いい) to express regret about a past action or inaction. When used with an affirmative verb, it means 'I should have done X.' When used with a negative verb (なければよかった), it means 'I shouldn't have done X' or 'I wish I hadn't done X.' This pattern conveys a strong emotional sense of missed opportunity or remorse. It is similar to たらよかった, which is slightly more colloquial. The pattern can only refer to past events, not future wishes.
Examples
- もっと早く出発すればよかった。 I should have left earlier.
- あの映画を見ればよかった。 I wish I had watched that movie.
- 傘を持ってくればよかった。 I should have brought an umbrella.
