The kanji 認 is a phono-semantic compound (形声文字). The left side is 言 (gen/gon, い(う), 言う) which means "to say" or "words." The right side is 刃 (jin, は), meaning "blade" or "sharp edge." Originally, 刃 provided the phonetic component. The combination suggests that what is said (言) should be considered as sharp and incisive, i.e., recognized or acknowledged as truth. Over time, the meaning evolved to represent recognition and agreement in a broader sense.
