transparent: [15] Etymologically, something that is transparent allows the light to ‘appear through’ it. The word comes via Old French from medieval Latin trānspārēns, the present participle of trānspārēre ‘be seen through’. This was a compound verb formed from the Latin prefix trāns- ‘across, through’ and pārēre ‘show, appear’ (source of English appear).

early 15c., from Medieval Latin transparentem (nominative transparens), present participle of transparere "show light through," from Latin trans- "through" (see trans-) + parere "come in sight, appear" (see appear). Figurative sense of "easily seen through" is first attested 1590s. The attempt to back-form a verb transpare (c. 1600) died with the 17c. Related: Transparently.
