grammar296 sentences
The conjectural auxiliary ~だろう (plain) / ~でしょう (polite) / でしょ (casual) expressing 'probably,' 'I suppose,' 'I think,' 'it must be.' Attaches to plain-form verbs, い-adjectives, and nouns (without the copula). Hedges a statement as the speaker's guess or inference rather than asserted fact. Often paired with intensifiers like きっと ('surely') or たぶん ('probably'). With rising intonation, ~でしょう / ~だろう? seeks confirmation ('right?'). Distinct from ~はず (expectation grounded in evidence).
