Pronunciation

  • /ˈskaɪˌlaɪn/[1]

Etymology

It is a compound from English sky + line.[2][3][4] The OED's first record is from 1815,[2] Etymonline and Merriam-Webster date it to 1824,[3][5] and Dictionary.com to 1855–60.[4] Etymonline notes that it was also written sky-line.[3]

Earliest recorded meaning

The line where the earth or the landscape seems to meet the sky; the horizon: 1815, in the Caledonian Mercury.[2] The OED also includes the representation of such a line in a painting or drawing,[2] and Etymonline notes that the word was at first often used of paintings.[3]

Semantic evolution

From the horizon itself, the word passed to the outline of what stands against it: from 1875 it is recorded for the silhouette of a city or of a group of buildings against the sky, first in a New York newspaper.[2] Merriam-Webster gives both the horizon and the outline of buildings or a mountain range.[5][6] A rare colloquial use for the line of the top row of pictures in an exhibition is recorded only in 1911.[2] In forestry, from 1915, a skyline is a high overhead cable used to carry logs from a logging site.[2][5] The verb followed: from 1872 in the passive, to be bordered by mountains or buildings on the horizon, then from 1895 to be seen outlined against the sky.[2][5]
