確かに

確かに is an adverb used to acknowledge or concede that something is true or valid. It adds a sense of agreement or relief that the speaker recognizes a point as correct, often softening a contrast with what comes next. It can begin a sentence or appear after a clause, and is common in both formal and informal contexts. The nuance is closer to “indeed,” “to be sure,” or “you’re right,” rather than just “yes.” It is frequently followed by a comma when used at the start of the sentence. Typical usage includes confirming an observation, conceding a point before offering a contrary view, or emphasizing the truth of a statement. Examples (Japanese → English): 1) 確かに、彼の話は長い。 → Indeed, his story is long. 2) その提案は確かに一理ある。 → That proposal certainly has a point. 3) 確かにそうだ。 → That’s true, indeed.
