N4 verb-grammar

Probably / right? 〜でしょう / だろう

Meaning

Two uses: (1) conjecture — "probably ~ / I think ~"; (2) seeking confirmation — " ..., right?". Polite form of だろう.

Formation

Notes

For conjecture, often paired with たぶん (probably) or 多分. In speech, rising intonation on でしょう makes it a confirmation question (天気いいでしょう? "Nice weather, huh?").
