Entries linking to suggestive
suggest v.
1520s, "place before another's mind; put forward a proposition," from Latin suggestus, past participle of suggerere "bring up, bring under, lay beneath; furnish, afford, supply; prompt" (see suggestion). Meaning "to act so as to call up the idea of (something else)" is from 1709. Related: Suggested; suggesting.
-ive
word-forming element making adjectives from verbs, meaning "pertaining to, tending to; doing, serving to do," in some cases from Old French -if, but usually directly from Latin adjectival suffix -ivus (source also of Italian and Spanish -ivo). In some words borrowed from French at an early date it has been reduced to -y (as in hasty, tardy).
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.
