Etymology
Etymology Information

'oxidise' originates from Modern French and Late Latin roots (via French 'oxydiser' and noun 'oxyde'), where the element 'oxyde' ultimately comes from Greek 'oxys' meaning 'sharp' or 'acid'.

Historical Evolution

'oxys' (Greek) → Latin/French 'oxyde' (meaning 'oxide') → French verb 'oxydiser' → English 'oxidise' (then past 'oxidised').

Meaning Changes

Initially related to the idea of 'sharp' or 'acid' (from Greek 'oxys'), the word's usage shifted to describe chemical combination with oxygen; it now specifically means 'to combine with oxygen' or 'to increase oxidation state.'
