attested in London criminal slang as adjective (1775), verb (1812), and noun (1851, of persons 1888), but probably older. A likely source is feague "to spruce up by artificial means," from German fegen "polish, sweep," also "to clear out, plunder" in colloquial use. "Much of our early thieves' slang is Ger. or Du., and dates from the Thirty Years' War" [Weekley]. Or it may be from Latin facere "to do." Related: Faked; fakes; faking.
: Sham; deceptive
A sham or deception; something spurious (1827+)
[origin uncertain; perhaps fr earlier feak, feague, or fig, ''to spruce up, esp by deceptive artificial means''; perhaps ultimately fr German fegen, ''clean, furbish,'' or Latin facere, ''to do'']
