double-edged
UK: ˌdʌb.əlˈedʒd | US: ˌdʌb.əlˈedʒd
adj. having two cutting edges (literal)
adj. having both positive and negative consequences (figurative)
The word combines "double" (from Old French "doble," Latin "duplus," meaning "twofold") and "edge" (from Old English "ecg," meaning "sharp side of a blade"). The suffix "-ed" turns it into an adjective. Originally describing blades with two sharp sides (e.g., swords), it evolved metaphorically to describe situations with dual outcomes—beneficial and harmful.
