The word 'standardise' is a modern English formation built upon the noun 'standard'. The noun 'standard' itself has a complex history, entering English from Old French 'estandard', meaning a rallying point or a military flag. This Old French term is likely derived from the Frankish 'standhard', literally 'stand firm', which combined a Germanic root for standing with one for hard or firm. The suffix '-ise', originating from the Greek verbal suffix '-izein' via Latin '-izare' and French '-iser', is a productive morpheme in English for creating verbs meaning 'to render or make into'. Therefore, 'standardise' logically means 'to make something conform to a standard', applying a consistent measure or model.

Structure: standard + ise - standard (Latin via Old French): The element denoting a level of quality, a model, or a measure for comparison. - ise (Greek via Latin and French): A verb-forming suffix meaning 'to make', 'to become', or 'to practise'.
