Etymology: "Halfheartedly" is simply "halfhearted" with the adverbial ending "-ly" attached, and the adjective is a compound of "half" and "heart." The heart, in older thinking, was the seat of courage and feeling, so a "half" heart meant a divided or partial commitment. The ending traces back through Proto-Germanic "-līkaz," a suffix meaning "having the form or appearance of," which became Old English "-līċe" and then Middle English "-ly." Its ancestry runs back to a Proto-Indo-European root *leyg-, meaning "to be like" or "form." Because the suffix is so productive, it attaches to nearly any adjective, and the result is a plain, transparent formation: the adverb describes doing something with only part of one's heart in it. Nothing in the word's construction is hidden, so its meaning follows directly from its parts.
