to sell
詅 centers on the act of selling, specifically with a nuance of hawking or peddling goods, often with words.
詅 combines 言 (speech) with 令, which likely contributes the sound. The character suggests selling through speech, such as hawking or peddling.
Words (言) and a commanding presence (令) come together: imagine a seller using persuasive speech to hawk goods, like a market vendor calling out to passersby.
For レイ, picture a seller laying out goods while calling out 'lay your eyes on this!' — 'lay' cues レイ, and the speech radical 言 reinforces the hawking scene.
