聆 is a literary/classical character rarely used alone in modern speech. It appears in compounds like 聆听 (to listen attentively) and 聆训 (to receive instruction). In everyday writing, 听 is preferred.
Ear radical on the left — pictograph of an ear with rim and lobe. Indexes 聆 in the hearing family with 听 listen, 聪 acute hearing, 聋 deaf. Marks the character firmly as a verb of attentive listening, distinct from the casual 听.
Right side 令 supplies the sound with a tone shift: lìng → líng. The same phonetic powers 玲 tinkle, 铃 bell, 龄 age, 零 zero. 令 also faintly hints at command and obedience — fitting 聆 as the respectful listening of a subordinate to a superior.
