past participle of drink, used as an adjective from mid-14c. in sense "intoxicated." In various expressions, e.g. "drunk as a lord" (1891); Chaucer has "dronke ... as a Mous" (c.1386); and, from 1709, "as Drunk as a Wheelbarrow." Medieval folklore distinguished four successive stages of drunkenness, based on the animals they made men resemble: sheep, lion, ape, sow. Drunk driver first recorded 1948. Drunk-tank "jail cell for drunkards" attested by 1912, American English. The noun meaning "drunken person" is from 1852; earlier this would have been a drunkard.
[in all senses drunk verges on being standard English]
The first case of intoxication on record is that of Noah (Gen. 9:21). The sin of drunkenness is frequently and strongly condemned (Rom. 13:13; 1 Cor. 6:9, 10; Eph. 5:18; 1 Thess. 5:7, 8). The sin of drinking to excess seems to have been not uncommon among the Israelites. The word is used figuratively, when men are spoken of as being drunk with sorrow, and with the wine of God's wrath (Isa. 63:6; Jer. 51:57; Ezek. 23:33). To "add drunkenness to thirst" (Deut. 29:19, A.V.) is a proverbial expression, rendered in the Revised Version "to destroy the moist with the dry", i.e., the well-watered equally with the dry land, meaning that the effect of such walking in the imagination of their own hearts would be to destroy one and all.
