Forms
tacite (plural tacites)[1]
Etymology
It is borrowed from Latin tacitus (“not spoken of, silent”),[2][3][4] the past participle used as an adjective of taceō (“to be silent”), the source of taire.[2][3][5] According to Littré the older French word was taisible, and the borrowed adjective only came into general use in the 16th century.[6]
Earliest recorded meaning
Bloch and Wartburg, the Grand Robert and Rey date the French word to 1466, when it meant “mute, silent”.[3][5][4] The sense “implied, not expressed” is found earlier in Old Gascon, in 1286, in the Gascon version of the Établissements de Rouen (permission expresse ou tacite), and in Old Occitan from 1352.[2][4]
Semantic evolution
The sense “silent”, taken straight from Latin, became literary and then archaic;[4][6] Littré already calls it an unused Latinism.[4][6] The current sense, “not formally expressed, understood”, is recorded in French from 1495 and had legal uses from the 16th century, as in tacite reconduction, the renewal of a lease or contract that neither party ends.[4][7] The adverb tacitement (1474) also meant “secretly, in a low voice” around 1495.[4]
