slim: [17] Slim is now quite an upbeat word, but that is a comparatively new departure, for historically it has been neutral if not downright derogatory. It was borrowed from Dutch slim ‘small, inferior’, which went back via Middle Dutch slim ‘slanting, bad’ to a prehistoric Germanic *slimbaz ‘oblique, crooked’ (source also of German schlimm ‘bad’). It may be distantly related to Latvian slīps ‘crooked, steep’.
