signature
✍️ 署名 = sign (署) + name (名): signing your name
署 means to sign or put your mark on a document; 名 means name. Together: writing your name on something, a signature. Sound hook: sho-mei, as in show me your signature.
名 — evening 夕 + mouth 口
A compound ideograph: in the dark of evening (夕), one cannot recognize others by sight, so the mouth (口) calls out a name to identify oneself. The original sense of 'name' broadened to include reputation, fame, and a measure word for people.
