Pronunciation

  • UK: /ˈɡɹiːnhaʊs/[1]
  • US: /ˈɡɹːnˌ(h)aʊs/[1]

Etymology

It was formed from English green + house in English.[2][3][4][5] In the gardening sense the first element is the noun green, in its old sense of plants or greenery, while in the pottery sense it is the adjective green, unfired.[2]

Earliest recorded meaning

A glass building in which plants that need sheltered, regulated conditions are grown: 1664, in John Evelyn's Kalendarium Hortense,[2][6][7] the 1660s in Etymonline.[3] Johnson (1755) defined it as a house where tender plants are sheltered from the weather, quoting the same work of Evelyn.[5]

Semantic evolution

Early greenhouses sheltered tender plants through the winter;[5] the modern sense has widened to any structure of glass or translucent plastic in which climate is regulated for plants.[2] In the pottery trade the word has named, since 1825, the area where unfired ware dries before going into the kiln.[2][6][7] In aviation slang of the Second World War it was used for the glass cover of a cockpit (1941).[2][6] Irish slang used it for a public lavatory, as in Joyce's Ulysses (1922).[8] The phrase greenhouse effect, the warming of a planet's surface by gases that trap heat, is recorded from 1937,[3] and the attributive use greenhouse meaning "of or caused by the greenhouse effect", as in greenhouse gas, from 1974.[7]
