Pronunciation

  • UK: /ˌbaɪə(ʊ)daɪˈvɜːsɪti/[1]

Etymology

It is formed from English bio- + diversity,[2][3][4] also spelled with a hyphen.[3] The combining form is from Ancient Greek βίος (bíos, “life, way of living”).[3] Diversity goes back through Middle English diversite and Old French diversete to Latin dīversitās (“contrariety; difference”), from dīversus (“turned different ways”), the past participle of dīvertō.[3] Dictionary.com calls it an Americanism.[5]

Earliest recorded meaning

The diversity of plant and animal life, especially as measured by the number of living species: 1985, in a table in the journal BioScience.[2][4]

Semantic evolution

Etymonline dates the word "by 1988", and Dictionary.com to 1985–90.[3][5] It became a term of conservation: Collins defines it with reference to conservationists' concern over the destruction of rainforests and other habitats.[6]
