'comment' originates from Latin, specifically the word 'commentum' (past participle of 'commentari'), where the prefix 'com-' meant 'together' and the root is related to 'mens' (mind/thought).

'comment' changed from Latin 'commentum' into Old French 'coment' and then entered Middle English as 'comment', eventually becoming the modern English 'comment'.

Initially, it referred to a consideration or contrivance (a thing thought about); over time it shifted to mean a spoken or written remark or explanation.
