Pronunciation
- IPA: /ʁe.fle.ʃiʁ/[1]
Forms
réfléchir[1] Reflekir (late 12th century), reflechir (about 1278), Old Burgundian reflenchir; the Académie wrote refleschir in 1694 and 1718, réfléchir from 1740.[2][3]
Etymology
It is borrowed from Latin reflectō (“to bend back; to turn back; to turn one's mind to”), adapted after fléchir.[3][2][4][5][1][6] The Latin verb is formed from re- (“back”) and flectō (“to bend”); in Medieval Latin it also meant to reflect, of a mirror (about 1240).[3][2] The sense “to think” goes back to Latin “reflectere animum” “to turn the mind back”.[7][8]
Compare Old Occitan reflectir, Spanish reflectir and Italian riflettere.[7]
Earliest recorded meaning
At the end of the 12th century reflekir, in the Dialogues of Gregory, means to direct the eye or the mind; in Jean de Meun's Roman de la Rose (1269–78) reflechir is to send back by reflection.[5][2][3]
Semantic evolution
In anatomy se reflechir meant to bend back on itself (Henri de Mondeville, 1314), a use that lasted into the 16th century (Paré).[3][7][8] The optical sense grew in importance in the 17th century with the science of optics, and it was applied to sound in 1718.[2]
The intellectual sense, “to think carefully”, is found in Bossuet (1672), after an isolated se reflechir “to meditate” (1609); Bouhours still preferred faire réflexion.[3][8][2] It spread in the 18th century to become the main sense, with réfléchir sur (1675) and réfléchir à (1701).[2] Verbes réfléchis (reflexive verbs) is a grammatical term from 1701.[3]
