What it means
よ is a sentence-ending particle that emphasizes or asserts the speaker's statement. It often presents information the listener may not know, corrects an assumption, or adds confidence to what is being said. It can follow either a familiar or polite sentence, but よ itself does not determine the politeness level.
Usage note
よ can sound forceful if used too often, especially when the statement is obvious or the listener did not ask for the information. Do not confuse it with ね, which usually seeks agreement or shared understanding.
