'noncontroversial' originates from English, formed by the prefix 'non-' (meaning 'not') attached to 'controversial'. 'Controversial' itself ultimately comes from Latin 'controversia', where 'contra-' meant 'against' and 'vertere' meant 'to turn'.

'controversial' developed from Latin 'controversia' (meaning 'a turning against, dispute') into Old French/Medieval Latin forms and then into Middle English before becoming the modern English adjective 'controversial'. The modern compound 'noncontroversial' is an English formation using the negative prefix 'non-'.

Initially related to the idea of a 'turning against' or formal dispute, the sense evolved to describe matters that cause public disagreement; 'noncontroversial' therefore means 'not causing such disagreement' in modern usage.
