Usage of 全然 (ぜんぜん)
全然 is commonly used with negative verbs to mean "not at all" or "completely not." For example, 全然わからない means "I don't understand at all."
However, in casual modern Japanese, especially among young people, 全然 can sometimes be used with positive verbs to emphasize a strong positive meaning, like 全然いい ("totally good"). This usage is informal and should be avoided in formal contexts.
Common collocations and patterns
- 全然 + negative verb: expresses complete negation (e.g., 全然できない "can't do at all")
- 全然 + adjective (negative form): emphasizes the negative quality (e.g., 全然面白くない "not interesting at all")
- 全然 + positive verb (informal): used for emphasis in casual speech (e.g., 全然大丈夫)
Notes
全然 is often confused with ぜんぶ (全部), which means "all" or "everything." Remember 全然 is about negation or emphasis, not quantity.
Use 全然 to strongly deny or negate something, and be mindful of the formality depending on your audience.
