Phono-semantic compound (形聲): semantic ⺼ (“meat”) + phonetic 利. Specialization of 利 (“benefit; profit”).
From 利 (“benefit; profit”), used as a euphemism for 舌 (sit6, “tongue”), which is homophonous to 折 (sit6, “to be at a loss”).
Alternatively, it may be from 舐 (OC *ɦljeʔ, “to lick”), preserving the Old Chinese initial *l- (Schuessler, 2007).
