でしょうRight?, Probably, Isn't it?

Both でしょう and だろう express conjecture (e.g., 'It's probably…') or seek confirmation when used with rising intonation in a question (e.g., 面白いでしょう？ or 面白いだろう？ = 'It's interesting, right?'). でしょう is more polite and used with strangers or those of equal or higher rank, while だろう is casual and blunt, used with close friends, family, and in informal settings.

でしょう is a form of です used when the speaker is uncertain, often translated as 'probably,' 'I guess,' or '...right?' when asking a question. In contrast, ね is a sentence-ending particle used to seek confirmation or agreement, similar to '...isn't it?' When combined (e.g., 面白いでしょうね), the sentence expresses both uncertainty and a request for agreement: 'It's probably interesting, isn't it?'

でしょう, in addition to expressing conjecture, can also seek confirmation or agreement from the listener (e.g., 面白いでしょう = 'Interesting, right?'). じゃないか is more forceful and casual, implying the speaker strongly believes something and expects the listener to agree (e.g., 面白いじゃないか = 'Interesting, isn't it!'). Note that でしょう is polite, while じゃないか is very casual.

かもしれない (polite form かもしれません) and でしょう both express uncertainty or possibility, softening a statement. The main difference is the degree of certainty: かもしれない expresses less certainty, similar to 'maybe' or 'might,' while でしょう (casual だろう) expresses a higher degree of certainty, similar to 'probably' or 'I guess.'

でしょう is a form of です used to express mild uncertainty (e.g., 'It's probably...') or to soften a statement. When used with a question intonation, it seeks the listener's agreement (e.g., 'It's this, right?'). In contrast, のではないだろうか expresses more doubt and seeks confirmation or approval (e.g., 'I wonder if it's…?'). In polite speech, だろう is replaced with でしょう, as in のではないでしょうか.
