Etymology

The word "primarily" derives from the Latin "primarius" (meaning "first in rank" or "chief"), which itself comes from "primus" (first). The suffix "-ly" is an Old English adverbial marker, turning the adjective "primary" into an adverb. Over time, "primarily" evolved to emphasize the principal aspect or initial cause of something, retaining its core idea of "firstness" while broadening to mean "mainly" in modern usage.
