Pronunciation

  • UK: /ˈæptɪˌtjuːd/[1]
  • US: /ˈæptɪˌtud/, /-tə-/[1]

Etymology

It is inherited from Middle English aptitude (“tendency, likelihood”),[2][3] borrowed from Late Latin aptitūdō (“fitness”),[2][3][4][5] a noun of quality formed from aptus (“joined, fitted”), the source of apt, with the suffix -tūdō.[4][5][6] Barnhart takes the word as borrowed either through Middle French aptitude or directly from the Late Latin noun,[7] and Dictionary.com and the Oxford Dictionary of English also bring it through French;[8][9] the OED, which first records it in 1548, derives it from French, where Littré finds the word in the 16th century.[6] The Shorter Oxford notes that the Late Latin noun is used by Boethius.[10] The same Latin noun gave attitude by way of Italian attitudine; it is a doublet of aptitude.[4][7][10]

Earliest recorded meaning

Tendency, likelihood: probably before 1425, in a Middle English translation of Guy de Chauliac's Grande Chirurgie, which speaks of an aptitude of vomityng.[2][7][4] The OED, in an entry not fully revised since 1885, has no record before 1548.[6]

Semantic evolution

The first sense, a natural tendency or disposition, is recorded in the OED from 1633,[6] in the Shorter Oxford from late Middle English.[10] The sense "natural capacity to learn, quick-wittedness" appears in 1548, in Udall's translation of Erasmus,[6][4] and "fitness for a purpose or position" in 1643, in Milton.[6][4] "Natural ability, talent for a pursuit" is recorded from 1793, and in 1775 Burke used the word of the capabilities of countries.[6] Johnson (1755) listed "fitness" and "tendency".[11] In the 17th and early 18th centuries aptitude was also used for attitude, a posture.[10] The Shorter Oxford cites its attributive use in aptitude tests.[10]
