Quiz: Remember the definition of mal de mer?
mid-14c., "a prompting to evil," from Anglo-French and Old French suggestioun, from Latin suggestionem (nominative suggestio) "an addition, intimation, suggestion," from suggestus, past participle of suggerere "suggest, supply, bring up," from sub "up" (see sub-) + gerere "bring, carry" (see gest). Sense evolution in Latin is from "heap up, build" to "bring forward an idea." Meaning "proposal" appeared by late 14c., but original English notion of "evil prompting" is preserved in suggestive (1630s, though the indecent aspect did not emerge until 1888). Hypnotism sense is from 1887.
suggestion sug·ges·tion (səg-jěs'chən, sə-jěs'-)
Implanting of an idea in the mind of another by a word or act so as to influence conduct or physical condition.
in psychology, process of leading a person to respond uncritically, as in belief or action. The mode of suggestion, while usually verbal, may be visual or may involve any other sense. The suggestion may be symbolic. For instance, a person who is allergic to roses may develop an attack of asthma from looking through a seed catalog. Suggestion, or suggestibility, plays a significant role in collective behaviour, especially in social unrest, and it constitutes the central phenomenon of hypnosis (q.v.).
