Translation guide
The English phrase "at all" is used to emphasize negation, questions, or conditions. In Japanese, there is no single direct equivalent; instead, various expressions and grammar patterns convey similar emphasis depending on the context.
Emphasize a complete lack or zero degree of something.
The most common way to say 'not at all'. 全然 (zenzen) is an adverb meaning 'completely' or 'at all', used with a negative verb or adjective.
I don't understand at all.
It's not interesting at all.
まったく (mattaku) also means 'completely' or 'at all', often slightly more emphatic or formal than 全然.
I don't remember at all.
Literally 'not even a little', used for emphasis in negative sentences.
I'm not tired at all.
Very casual and emphatic, meaning 'not even a tiny bit'. Often used in spoken Japanese.
I haven't heard a thing about it.
Ask whether something exists or happens to any degree, often implying doubt or expecting a negative answer.
Used in questions to ask if there is any amount at all. Often implies the speaker suspects there is little or none.
Express that something might happen only to a minimal extent, or might not happen.
Used to say 'even if it does happen, at most...' conveying 'if at all'.
Emphasize that something is the absolute best/worst etc. among all possibilities.
Means 'more than anything', often used to say 'the best at all'.
While 全然 can be used with positive verbs in casual speech (全然いいよ = It's totally fine), in formal or standard Japanese it is primarily used with negatives. Using it with positives may sound slangy or incorrect in formal contexts.
It's totally fine. (casual)
Both mean 'completely (not)' in negative sentences. まったく is slightly more formal and emphatic, often used in written language or serious speech. 全然 is more common in everyday conversation.
