Etymology
Etymology Information

'countercurrent' is an English compound formed from the prefix 'counter-' and the noun 'current'. 'counter-' ultimately derives from Latin 'contra' (via Old French 'contre'), where 'contra' meant 'against'. 'current' derives from Latin 'currere' meaning 'to run' (via Old French 'courant' and Middle English).

Historical Evolution

'counter-' came into English via Old French 'contre' from Latin 'contra', and 'current' came into English via Old French 'courant' from Latin 'currens' (from 'currere'); these elements were combined in English to form the compound 'counter-current' (often hyphenated) and later the solid form 'countercurrent'.

Meaning Changes

Initially, the elements literally meant 'against' + 'running'; the compound originally referred to a flow running against another flow, and this basic sense of 'flowing or moving in the opposite direction' has been retained in modern usage.
