Pronunciation

  • IPA: /ˈɛəˌlaɪn/ (UK); /ˈɛɹˌlaɪn/ (US)[1]

Etymology

It is a compound of air and line,[2][3][4] also written air-line.[2][3]

Earliest recorded meaning

A beeline, a straight line between two points on the earth's surface, as through the air rather than over the terrain: 1813, chiefly North American.[2][3]

Semantic evolution

From 1853 and later in the 19th century it was used especially of American railways that ran directly between big cities instead of meandering from town to town.[2] A regular service of aircraft between places, and a company providing it, is from 1914 in Etymonline;[2][3] Merriam-Webster's Collegiate dates the word to 1901 and the RHWU to 1910–15.[5][4] A hose carrying air under pressure is another sense.[6]
