defenseless

The word defenseless is a modern English compound formed from the noun "defense" and the suffix "-less." The root "defense" originates from the Latin verb defendere, meaning "to ward off, protect," which itself is composed of de- (off, away) and fendere (to strike). The suffix "-less" is a native English element from Old English -lēas, conveying a state of being without something. Therefore, the literal construction "without defense" directly and logically yields the modern abstract meaning of being vulnerable and unprotected against threat or danger.

Structure: defense + less defense: From Latin defensa (a warding off, protection), via Old French defense. It functions as the core noun root meaning "protection." less: From Old English -lēas (devoid of, free from). It functions as an adjective-forming suffix meaning "without."
