1.
sweepingly, unconditionally, without exception
Used almost exclusively with negative predicates to mean "cannot simply say" or "cannot generalize." Indicates that a blanket statement would be inaccurate because there are exceptions or nuances.
一概には言えない。
You can't say that unconditionally.
安いからといって、一概に悪いとは限らない。
Just because it's cheap doesn't necessarily mean it's bad.
成功の理由は人それぞれで、一概に努力だけのおかげとは言えないだろう。
The reasons for success vary from person to person, and you can't simply attribute it all to effort.
一概に is a formal adverb that almost always appears with a negative predicate. The most common pattern is 一概に〜とは言えない (one cannot simply say that ~).
COMMON PATTERNS:
- 一概に〜とは言えない (cannot simply say ~)
- 一概に〜とは限らない (is not necessarily ~)
- 一概に否定できない (cannot flatly deny)
- 一概に比較できない (cannot simply compare)
USAGE NOTES:
- Almost never used in affirmative sentences
- Common in essays, news commentary, and formal discussions
- Expresses intellectual nuance — the speaker acknowledges complexity rather than making a sweeping judgment
