Translation guide
The English word 'maybe' is used to express uncertainty or possibility. In Japanese, this is most commonly expressed with the sentence-ending particle かもしれない or the adverb たぶん. The choice depends on the level of certainty, formality, and whether you are making a guess or suggesting a possibility.
Maybe it will rain tomorrow.
Standard way to express 'maybe' as a possibility.
Maybe I'll go to the party.
Casual, expresses a tentative plan.
The speaker is not sure about something, but thinks it is possible. This is the most common use of 'maybe'.
Attach to the plain form of a verb, adjective, or noun. This is the most direct and common equivalent of 'maybe' or 'might'. It expresses a possibility, often with a nuance of 'it could be that...'.
Maybe he won't come.
Maybe that's true.
An adverb meaning 'probably' or 'maybe'. It is often used with 〜だろう or 〜と思う to soften the assertion. In casual speech, it can stand alone or with a plain form verb.
Casual abbreviation of かもしれない. Used in informal conversation.
Maybe it'll rain tomorrow.
Expresses conjecture. でしょう is polite, だろう is plain. Often used with たぶん. It translates to 'probably' or 'I guess'.
Means 'maybe' or 'possibly' with a nuance of 'by any chance'. Used when the possibility is low or unexpected.
The speaker is proposing an idea without being forceful. 'Maybe' softens the suggestion.
These patterns mean 'why don't you...?' or 'how about...?'. They are used to make casual suggestions. Adding もしかしたら or たぶん is not necessary; the tentative tone is built into the pattern.
Maybe you should ask him.
Often used with 〜かもしれない to mean 'maybe' or 'perhaps'. It adds a sense of 'possibly' and is slightly more tentative than たぶん.
The speaker is making a guess but is not at all sure. 'Maybe' here is close to 'perhaps'.
たぶん is an adverb meaning 'probably', while かもしれない is a sentence-ending expression meaning 'might' or 'maybe'. たぶん is often used with 〜だろう/〜でしょう or 〜と思う to express a higher degree of certainty. かもしれない expresses a simple possibility without implying probability. In casual speech, たぶん can be used alone, but かもしれない is more common for 'maybe'.
I'll probably go. (higher certainty)
I might go. (just a possibility)
English speakers often use 'maybe' as a one-word answer. In Japanese, answering with just たぶん is possible in casual speech, but it can sound abrupt. It's more natural to repeat the verb or use a full phrase like そうかもしれない (that might be so) or たぶんね (maybe, with a softening particle).
Maybe I left my keys at home.
Maybe we should wait a little longer.
たぶん大丈夫だよ。
Maybe it'll be fine.
I think maybe he doesn't know.
Maybe he will come.
ひょっとすると彼は来るかもしれない。
Maybe, just maybe, he'll come.
Maybe he knows.
ことによると彼は来ないかもしれない。
