early 14c., originally in legal sense of "to call" to a higher judge or court, from Anglo-French apeler "to call upon, accuse," Old French apeler "make an appeal" (11c., Modern French appeler), from Latin appellare "to accost, address, appeal to, summon, name," iterative of appellere "to prepare," from ad- "to" (see ad-) + pellere "to beat, drive" (see pulse (n.1)). Related: Appealed; appealing.
Probably a Roman metaphoric extension of a nautical term for "driving a ship toward a particular landing." Popular modern meaning "to be attractive or pleasing" is quite recent, attested from 1907 (appealing in this sense is from 1891), from the notion of "to address oneself in expectation of a sympathetic response."
