elusive
UK: ɪˈluːsɪv | US: ɪˈluːsɪv
adj. difficult to find, catch, or achieve
adj. hard to define or understand
adj. tending to evade or escape
The word "elusive" traces back to Latin eludere ("to evade, escape"), formed from e- (meaning "out") and ludere ("to play"). The root lus- (from ludere) metaphorically implies "dodging like in a game," evolving into the sense of avoiding capture or comprehension. The suffix -ive turns it into an adjective, describing something that "plays hard to get." Over time, "elusive" expanded from physical evasion (e.g., prey) to abstract ideas (e.g., answers).
