Etymology: "Fatuously" is an adverb built from "fatuous" and the suffix "-ly," so the interesting history lies in the first part. "Fatuous" comes from the Latin "fatuus," meaning "foolish" or "silly," the same root that gives English "fatuity." The adjective has a dull, stolid cousin in the Latin sense of foolishness, and that is the quality the word carries when it describes behaviour that is confident yet pointless. The suffix tells its own story. The ending "-ly" descends from Old English "-līċe," which itself grew out of a Germanic root meaning "body" or "form," so that "like" and "-ly" share a deep ancestry. Adding "-ly" to an adjective is one of the most ordinary processes in English, which is why "fatuously" simply means "in a fatuous manner." Its sense of silly self-assurance comes from the adjective, which describes someone who is pleased with themselves while being quite foolish.
