Pronunciation

  • UK: /ˌpɹɒsˈθɛtɪk/[1]
  • US: /ˌpɹɑsˈθɛtɪk/[1]

Etymology

It is borrowed from New Latin prostheticus,[2] a Latinized form of Ancient Greek προσθετικός (prosthetikós, “adding, furthering”),[2][3][4][5] from πρόσθετος (prósthetos, “added”),[2][3][5] the verbal adjective of προστιθέναι (prostithénai, “to put to, add”).[3][5] That verb is formed from πρός (prós, “to”) and τιθέναι (tithénai, “to put, place”), the source of thesis.[5][6] The New Latin word is recorded in a medical sense in a title of 1677.[2] The Shorter Oxford takes it as formed from prosthesis after synthesis and synthetic.[7] The biochemical sense follows German prosthetisch, used by A. Kossel in 1892.[2]

Earliest recorded meaning

In grammar, of a letter or syllable added to the beginning of a word: 1738, in R. Grey's work on learning Hebrew.[2][4] Etymonline dates the word to 1837 in this sense.[3]

Semantic evolution

The grammatical sense follows that of prosthesis, the adding of a letter or syllable to a word, and is now rare.[2][7] The medical sense, relating to artificial replacements for body parts, is recorded from 1872 in the OED;[2] Etymonline dates it to 1902.[3] In biochemistry, from 1898, a prosthetic group is a non-protein group bound to a protein.[2][4] From 1933 the word was used as a noun for a prosthesis, and later also for an artificial feature worn as theatrical make-up or for special effects; the matching adjective sense in the performing arts is recorded from 1960.[2]
