Pronunciation

  • UK: /ˈæk.sɪ.əl/[1]
  • US: /ˈæk.si.əl/[1]

Etymology

It is formed from English axis + -al,[2][3][4][5] also analysed as axi- with -al.[6][7] The OED takes the base directly from Latin axis (“axle, pivot, axis of the earth”).[5] Etymonline traces the Latin noun to Proto-Indo-European *aks- (“axis”), the source also of Old English eax (“axle”).[2]

Earliest recorded meaning

Of or relating to an axis: Merriam-Webster dates this sense to 1823,[6] Etymonline dates the word to 1830,[2] and Dictionary.com to 1840–1850.[7] The OED's first record, for "forming an axis", is from 1849, in Murchison's Siluria.[5]

Semantic evolution

The OED records "belonging to an axis" from 1859 and "round or about an axis" from 1862, in Herbert Spencer's First Principles.[5] In engineering an axial flow is a flow parallel to the axis of rotation, as in some turbines.[3] In chemistry the word is used of bonds that run roughly parallel to the main axis of a ring such as cyclohexane, as opposed to equatorial ones.[6]
