Etymology

The word "doubly" originates from the Middle English term "doubly," derived from Old French "doble" (double) + the adverbial suffix "-ly." The root "double" traces back to Latin "duplus" (twofold), combining "duo" (two) and "-plus" (fold). The suffix "-ly" is a productive English morpheme used to form adverbs from adjectives, indicating manner or degree. Thus, "doubly" literally means "in a double manner" or "to twice the extent," reflecting its function as an intensifier or qualifier.
