Origin & History of “standard”

Standard ‘flag, banner’ (12th c.) denotes etymologically something that is ‘extended’ or unfurled. The word comes from Anglo-Norman estaundart ‘flag displayed on a battlefield so that troops can rally to it’. this was a derivative of Old French estendre ‘extend’ (first cousin of English extend). The sense ‘criterion, norm’, which emerged in the 15th century, is probably a metaphorical application of the notion of the ‘royal standard’ or banner as being the point from which authoritative commands (as of standards of weight and measurement) are issued. Standard ‘upright object, such as a tree’ (13th c.) is probably an alteration of stander.
