Selected source glosses provide context, not a complete modern definition inventory

The noun is derived from Middle English tappe (“hollow device for controlling the flow of liquid from a hole, cock, faucet, spigot; hole through which the liquid flows; the liquid which thus flows”), from Old English tæppa, from Proto-West Germanic *tappō, from Proto-Germanic *tappô (“a plug, tap; peg; tapering stick”), from Proto-Indo-European *deh₂p- (“to lose; to sacrifice”). Doublet of tapa. The verb is derived from Middle English tappen (“to obtain (liquid, chiefly liquor) from a tap; to obtain and sell (liquor)”), from Old English tæppian (“to provide (a container) with a stopper; to obtain (liquid) from a tap”), and then either: * from Old English tæppa (see above) + -ian (suffix forming verbs); or * from Proto-Germanic *tappōną, from *tappô (noun) (see above). Verb etymology 1, verb sense 1.3.5 (“to turn over (a playing card or playing piece) to remind players that it has already been used in that round”) alludes to the abilities or resources of the card or piece having been drawn on to the point of temporary exhaustion: see verb etymology 1, verb sense 1.3.2.

Original entry ↗
verb

To strike (someone or something), chiefly lightly with a clear sound, but sometimes hard. · Also in the form tap on the shoulder: to arrest (someone). · To have sexual intercourse with (someone). · To shoot (someone or something) with a firearm.

noun

A light blow or strike with a clear sound; a gentle rap; a pat; also, the sound made by such a blow or strike. · The smallest amount of work; a stroke of work. · One of the metal pieces attached to the sole of a tap dancer's shoe at the toe and heel to cause a tapping sound. · A shot fired from a firearm.

Selected source glosses provide context, not a complete modern definition inventory

The verb is derived from Middle English tappen, teppen (“to give (something) a knock or tap; to hit (something) lightly, pat, tap”), either: * imitative of the making of a tapping sound; or * from Old French tapper, taper (“to tap”) (modern French taper), from Frankish *tappōn, *dabbōn (“to strike”), or from Middle Low German tappen, tapen (“to rap, strike, tap”), or from Proto-Germanic *tabōną (“to grope, to grapple, to claw”), maybe via a Old Norse *tapa (“to strike”), as seen in the derivative tapsa (“to tap”) Doublet of dab and tave. Verb etymology 2, verb sense 1.1.1 (“to arrest (someone)”) and etymology 2, verb sense 1.6 (“to choose or designate (someone) for a duty, etc.”) allude to a police officer or other person tapping someone on their shoulder to catch their attention or to select them. The noun is derived from Middle English tap, tappe (“light blow or hit”), and then either: * from Middle English tappen (verb) (see above); or * from Old French tape (“light slap or touch, pat”) (modern French tape), from tapper, taper (verb) (see above). Cognates * German tappen (“to fumble; to grope”) * Icelandic tappa, tapsa, tæpta (“to tap”)

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
