Etymology

The word "extremely" derives from the Latin extremus (superlative of exter, meaning "outer"), which entered Middle English via Old French extreme. The suffix -ly (from Old English -līce) converts adjectives into adverbs. Thus, "extremely" literally means "in an utmost manner," reflecting its modern use to intensify degree or emphasis.
