Etymology Information

'contaminate' originates from Latin, specifically the word 'contaminare', where 'con-' meant 'together' and the root is related to 'tangere' meaning 'to touch' (hence 'to touch together, defile').

Historical Evolution

'contaminate' changed from Medieval Latin 'contaminatus'/'contaminare' and entered English in the late 15th century via Medieval/Church Latin and Anglo-French usage, eventually becoming the modern English 'contaminate'.

Meaning Changes

Initially, it meant 'to touch together' or 'to defile/soil'; over time it evolved into the current sense of 'to make impure, polluted, or harmful by introducing undesirable substances or influences'.
