Japanese 298 - Conjecturing with でしょう

One of the most common ways でしょう is used is to express supposition or a guess about something. It's equivalent to English expressions like probably, maybe, or I guess.

By using でしょう before the question particle , you can make a question more tentative. In this way, the question sounds softer, less direct, and more polite.

Just as the particle , でしょう can also be used to seek confirmation. The difference is that when using , the speaker is fairly confident that the listener will agree, whereas with でしょう, there is more uncertainty about whether the listener agrees.
