挂失
guà shī · HSK 7
to report the loss of something
📋💳 挂 register/hang up + 失 lose = register a loss (e.g. a lost bank card)
挂 here means to put on record (like hanging a notice up), and 失 means loss. Together they mean to formally report something lost so it can be cancelled, like a stolen card or ID.
挂 — hand radical 扌 + 圭 (jade tablet, phonetic)
挂 is a semantic-phonetic compound. The hand radical 扌 gives the meaning, since hanging something requires the hand to place it on a hook or peg. The right side 圭 (guī, a jade tablet) supplies the sound, close to the modern reading guà. Originally written 掛, it meant to suspend or hang up.
