suggestion (n.)

mid-14c., "a prompting to evil," from Anglo-French and Old French suggestioun "hint, temptation," from Latin suggestionem (nominative suggestio) "an addition, intimation, suggestion," noun of action from suggestus, past participle of suggerere "bring up, bring under, lay beneath; furnish, afford, supply; prompt," from sub "under; up from below" (see sub-) + gerere "bring, carry" (see gest). Sense evolution in Latin is from "heap up, build" to "bring forward an idea." Meaning "proposal, statement, declaration" appeared by late 14c., but original English notion of "evil prompting" remains in suggestive. Hypnotism sense is from 1887.
