all-defensive

The word is a modern English compound adjective, formed by combining the intensifier "all" with the adjective "defensive." "All" originates from the Proto-Germanic allaz, carrying the fundamental sense of "whole, entire," which evolved into its modern adverbial use to mean "completely." "Defensive" entered English via Old French from the Latin defensivus, itself derived from defendere, meaning "to ward off." The compound "all-defensive" emerged primarily in the lexicon of sports, particularly basketball, to describe a player or strategy wholly dedicated to preventing the opposing team from scoring, thus extending the literal meaning of "entirely protective" into a specific, context-bound term of praise for athletic prowess.

Structure: all (entirely) + defensive (protective) - all: From Old English eall (all, every, entire). In this compound, it functions as an intensifying prefix meaning "completely" or "exclusively". - defensive: From Latin defensivus (serving to ward off), from defensus, past participle of defendere (to ward off, protect). In this compound, it functions as the core adjective meaning "protective" or "intended for defense".
