protective adj.

"cover or shield from danger, harm, damage, exposure, trespass, temptation, insult, etc.," early 15c., protecten, from Latin protectus, past participle of protegere "to protect, defend, cover over, cover in front" (source also of French protéger, Old French protecter, Spanish proteger). This is from pro "before" (from PIE root *per- (1) "forward," hence "in front of, before") + tegere "to cover" (from PIE root *(s)teg- "to cover").

Applied with a wide range, both literal and figurative. The sense in political economy, "guard or strengthen against foreign competition by means of tariffs, etc.," is by 1789. Related: Protected; protecting.

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).

also over-protective, "that protects to an undue or unhealthy extent," 1930, from over- + protective. Related: Overprotectively; overprotectiveness.
