Word Origin & History

tap
"strike lightly," early 13c., from O.Fr. taper "tap, rap, strike," from a Gallo-Romance or Germanic source ultimately imitative of the sound of rapping. Meaning "to designate for some duty or for membership" is recorded from 1952, from notion of a tap on the shoulder. The noun is attested from c.1300.
Tap dancer first recorded 1927, from tap (n.) in the sense of "metal plate over the heel of a shoe" (1680s).

tap
"stopper, faucet," O.E. tæppa, from P.Gmc. *tappon (cf. M.Du. tappe, Du. tap, O.H.G. zapfo, Ger. zapfen). Originally a tapering cylindrical peg (hence taproot). Meaning "device to listen in secretly on telephone calls" is from 1923, from the verb in this sense, originally (1869) with reference
to telegraph wires. Phrase on tap "ready for use" is recorded from late 15c. The verb meaning "to supply with a tap" is from O.E. tæppian. Extended sense of "make use of" is first recorded 1570s. Tap-room is from 1807. Tapped out "broke" is 1940s slang, perhaps from the notion of having tapped all one's acquaintances for loans already (cf. British slang on the tap "begging, making requests for loans," 1932).
