early 14c., "to delay, retard" (transitive), of uncertain origin. Some suggest a connection to Latin tardare "to delay," or Old English tergan, tirgan "to vex, irritate, exasperate, provoke," which yielded a Middle English verb identical in form to this one. Intransitive meaning "to linger" is attested from late 14c. Related: Tarried; tarrying; tarrysome.

1550s, from tar, n.1 + -y(2). Tarry-fingered "dishonest, thieving" is from 1825.
