shady

Etymology

It is formed from English shade + -y.^{[2][3][4][5][6]} The noun shade goes back to Old English sceadu (“shade, shadow”).^[3][2] Old English had a different adjective, sceadlic (“shady”), and the Elizabethans also used shadeful.^[3]

Earliest recorded meaning

Giving shade: the first record is in Spenser's Shepheardes Calender (1579).^[2][5][3]

Semantic evolution

Within a decade the adjective also meant "shaded, protected by shade" (1589, in Greene),^[2][3] and, in Sidney (before 1586), "living in the shade", of someone choosing retirement and safety.^[2] In the 17th century it could mean "opaque, dark" (from 1605, in Bacon) or "shadowy, faintly perceptible" (1626), senses now obsolete,^[2][4] and poets later called the night shady (1746–1896).^[2] Johnson (1755) defined it as full of shade and sheltered from glare.^[7] The figurative phrase on the shady side of, older than a given age, is recorded from 1807.^[2][3] The colloquial sense "of questionable merit, unreliable" appears in 1848, in Clough's Bothie of Toper-na-Fuosich, and the OED suggests it began as university slang;^[2][3] by 1862 it meant "disreputable, unable to bear investigation".^[2][3] Etymonline thinks the later sense may come from or have been strengthened by the earlier one, perhaps on the notion of something that cannot bear the light.^[3] American college slang of 1856 used shady for "dull, slow", and later American slang for "odd" or "secretive".^[8] In Northamptonshire dialect it meant shy.^[9]
