Translation guide
Expresses future negation, refusal, or strong determination not to do something. In Japanese, this is conveyed through verb conjugations, auxiliary verbs, and set phrases rather than a single word.
To say that something will not happen or someone will not do something in the future, in casual or plain speech.
The plain negative form of a verb. This is the most direct equivalent of 'will not' in casual contexts.
It will not rain tomorrow.
I think he will not come.
Adds a sense of probability or conjecture, similar to 'probably will not'.
He probably will not come.
To politely say that something will not happen or someone will not do something.
The polite negative form of a verb. Use this in formal or polite situations.
It will not rain tomorrow.
To express a strong refusal or determination not to do something, equivalent to 'I will not...' or 'I refuse to...'.
Expresses intention not to do something. 'I have no intention of...'
I will not see him again.
To express that something cannot be done or is impossible, often overlapping with 'will not' in English.
Literally 'cannot do', used for inability or impossibility.
Japanese does not have a direct future tense auxiliary like English 'will'. Future actions are expressed through context, time words, or the plain form of the verb. Avoid trying to translate 'will' as a separate word.
Use ない for casual speech, ません for polite speech. The meaning is the same, but the social context dictates which to use.
I will not attend the meeting.
Polite conjecture, 'probably will not'.
He probably will not come.
A literary or formal negative volitional form, expressing strong determination not to do something. Attaches to the dictionary form of godan verbs, or the stem of ichidan verbs.
I will never repeat that mistake again.
An emphatic, colloquial way to express strong denial or refusal. Often used by male speakers.
I will not lose to a guy like that!
This machine will not be repairable.
Expresses that one cannot do something due to social or moral obligation, 'cannot afford to...'
