Origin & History of “reflect”
To reflect something is etymologically to ‘bend it back’. The word comes via Old French reflecter from Latin reflectere ‘bend back’, a compound verb formed from the prefix re- ‘back’ and flectere ‘bend’ (source also of English deflect (17th c.), flex (16th c.), flexible (15th c.), inflect (15th c.), etc). The word’s optical application is a post-Latin development.
