Pronunciation

  • /ˈklaʊ̯diː/[1]
  • US: /ˈklæʊ̯diː/[1]

Etymology

It is inherited from Middle English cloudi, also cludiȝ,[2][3] inherited from Old English clūdig (“rocky, hilly”),[4][5][3][6] from clūd (“rock, hill”) and -ig, the ancestor of -y.[5][7] The Middle English Dictionary takes it as partly the Old English word and partly a new formation on cloud,[2] and the OED treats the modern word as formed from English cloud + -y, noting that Old English already had clūdig from clūd.[7][8] The noun cloud itself meant a mass of rock or a hill in Old English, and is probably related to clod.[4][9]

Earliest recorded meaning

Rocky, hilly: in the Old English translation of Orosius, where the land of the Northmen is described as very rocky in places.[7][6] The OED records this sense until about 1400,[7] and Orm still has it about 1175.[2] In the modern sense, made of or like cloud, it is first recorded about 1300, in a life of St Brendan.[7][2][4]

Semantic evolution

The adjective followed its noun: when cloud passed from "rock mass" to "mass of vapour in the sky" around 1300, apparently from the likeness of cumulus clouds to rock masses,[4][9] cloudy came to mean "of the nature of cloud".[7][4] The sense "full of clouds, overcast" is recorded from before 1387, in Trevisa.[7][4] Figurative uses came early: Chaucer's translation of Boethius (about 1374) already uses it for something darkened by trouble or gloom;[7][4] from about 1400 it was used of thought or language that is obscure or unclear.[7] Of liquids and other things that are not transparent, it is recorded from 1587.[7][4] In B.E.'s dictionary of cant, about 1698, it meant dark-complexioned;[10] from 1886, in R. L. Stevenson, it meant under a cloud, of doubtful reputation.[7][10] In Nottinghamshire dialect it meant dusk, dark.[11]
