Etymology
The word 'counteract' is a transparent compound formed within English from the prefix 'counter-' and the verb 'act'. The prefix 'counter-' entered English via Anglo-French from the Latin preposition contra, meaning 'against'. The verb 'act' derives from the Latin past participle actus of the verb agere, meaning 'to drive, lead, do'. The literal, morphemic meaning is "to act against." This logic perfectly captures the modern abstract sense: to perform an action designed to oppose, neutralize, or undo the effects of another action or force.
Analysis
- counter: From Latin contra (against, opposite). A prefix indicating opposition or reciprocation. - act: From Latin actus (a doing, a driving), from agere (to do, to drive, to lead). The core verb meaning to do or perform.
