Etymology

The word "marginally" derives from the Latin margo (meaning "edge" or "border"), which evolved into the English noun "margin." The suffix -al transforms it into an adjective ("marginal"), and -ly further converts it into an adverb. The progression reflects a shift from a physical boundary ("margin") to a figurative sense of minimal significance ("marginally").
