discuss, talk
談 centers on exchanging ideas through speech: discussing a topic or talking with others.
談 combines 言 (speech) with 炎, which likely contributes the sound and may suggest the heat or intensity of a discussion.
Words (言) and flames (炎) together: imagine a heated discussion where words fly like sparks.
For ダン, picture a lively discussion at dawn: dawn -> ダン, and the talk lights up the morning.
