おそらく

An adverb meaning “probably” or “perhaps.” It is used to hedge a statement and express a cautious expectation without asserting certainty. It is common in both spoken and written Japanese and often makes the sentence sound more formal or tentative than using きっと or たぶん. It typically precedes the main clause or verb phrase and can be followed by a sentence-ending expression like だろう or でしょう to indicate probability. Examples: - おそらく明日は晴れるでしょう。 It will probably be sunny tomorrow. - おそらく彼は来ないだろう。 He probably won’t come. - おそらくはその案が最適だと思う。 Perhaps that plan is the best option.
