The kanji 説 is a 形声文字 (keisei moji), a phono-semantic compound. It combines the radical 言 (げん/gon), meaning "speech" or "words," with the phonetic component 兌 (だ/da), which contributes to the pronunciation and originally meant "to exchange" or "to be pleased." Thus, the character originally meant "to explain" or "to make an exchange of words." The combination of 言 and 兌 suggests an act of using speech to convey information or exchange ideas.
