Reinforce

ree-in-FORS /ˌriːɪnˈfɔːrs/

verbB2GRESAT

formalinformal

To strengthen or support (an object or substance), especially with additional material; to strengthen (an existing idea, feeling, or habit).

This word implies making something stronger or more firm, whether physically or conceptually. In the context of ideas, it suggests a confirmation or validation that makes a belief more entrenched.

The story behind the word. The word 'reinforce' comes from the Old French 'reinforcier,' combining the prefix 're-' (meaning 'again' or 'back') with 'enforcier' (to strengthen, from 'en-' meaning 'into' and 'force'). So, it literally means 'to strengthen again' or 'to make stronger.' This origin highlights its core meaning of adding strength or support to something that already exists, whether a physical structure or an abstract idea.
