Pronunciation

  • Classical: [trãːˈspaː.re.oː][1]
  • Ecclesiastical: [tranˈspaː.re.o][1]

Forms

trānspāreō (present infinitive trānspārēre, perfect active trānspāruī, supine trānspāritum); second conjugation, no passive[1]

Etymology

It is formed from Latin trāns- (“across, through”) + pāreō (“to appear, be seen”).[1][2] The DMLBS marks it as a medieval formation from these Classical Latin elements.[2]

Earliest recorded meaning

The DMLBS records it in British medieval Latin of the scholastic writers on optics and nature: Robert Grosseteste uses the present participle of water as a body through which light passes, like air, horn, ice and glass, and Roger Bacon of a stone that one can see through.[2]

Semantic evolution

The verb meant both to show through something (transitively, in an alchemical treatise, of the whiteness of earth showing through the clearness of water) and to be transparent, the second mostly in the present participle used as an adjective.[2] Bacon gives trānspārēns among the words that mean the same thing as diaphanus, with perspicuus, pervius, trānslūcēns and lūcidus.[2] Du Cange glosses it with Classical pellūcēre “to shine through”, and the noun trānspārentia with “transparency”.[3]

Through the participle it gave the English adjective.[4] Its descendants include Italian trasparire and Romanian transpărea.[1]

Timeline

  • early 15th century – English borrows the Medieval Latin participle as transparente.[4]
  • c. 1600 – An English back-formation transpare “appear through something” is recorded, but it died out in the 17th century.[4]

Meanings
