Pronunciation

  • UK: /dʒiˈɒlədʒɪst/[1]
  • US: /d͡ʒiˈɑːlədʒɪst/[1]

Etymology

It is formed from English geology + -ist.[2][3][4][5] Geology is from New Latin geologia (“the study of the earth”),[3][6] compounded of geo- and -λογία (-logía).[6][3] In Medieval Latin geologia had meant the study of earthly things, especially law.[3][6] Etymonline notes the competing words geologer (1819) and geologian (1811).[3]

Earliest recorded meaning

An expert in geology: 1778, in an English translation of Alberto Fortis's Travels into Dalmatia.[2] Etymonline dates the word to 1792,[3] and Dictionary.com to 1785–95.[5]

Semantic evolution

The word appeared at about the time that geology itself took its modern sense of the science of the earth's structure and history, recorded from 1788.[2] Earlier, from 1731, geology had meant the science of the earth as a whole.[2]

Timeline
