Pronunciation

  • UK: /əˌdæptəˈbɪlɪti/[1]
  • US: /əˌdæptəˈbɪləti/[1]

Etymology

It is formed from English adapt + -ability.[2][3][4] Adapt is partly from Middle French adapter and partly from Latin adaptō (“to make suitable, fit”),[2] formed from ad- (“to”) and aptō (“to fit, join”), from aptus (“fitted”), the source of apt.[3][2]

Earliest recorded meaning

The quality or state of being adaptable: 1661, in R. Lovell's Panzōoryktologia.[2][5] Etymonline dates the word to the 1660s.[3]

Semantic evolution

The noun is recorded before the adjective it now seems to be built on: the OED dates adaptable only to 1692,[2] and Etymonline to the 1680s.[3] The 1989 edition of the OED defined it as the quality of being adaptable, the capacity of being adapted or of adapting oneself, a potential fitness, used with to or for.[6] In modern use it is especially a term of evolutionary biology, for the ability of an organism to vary in response to, or under the influence of, outside conditions.[3][1]
