protective

The word 'protective' is built upon the Latin verb protegere, meaning "to cover in front" or "to shield." This verb itself is a compound of the prefix pro- (forward, in front) and the verb tegere (to cover), a root with Proto-Indo-European ancestry related to concepts of covering and roofing. The suffix -ive, also from Latin (-ivus), is a highly productive adjectival suffix that transforms the action of the verb into a quality or tendency. Thus, the literal morphemic logic of "tending to cover or shield" evolved seamlessly into the modern abstract meaning of having the intention or quality of keeping something safe from harm.
