When we say someone is slim, we usually mean that they are slender or thin, although the word has some other, less common, meanings. English use of the adjective dates to at least 1657,
We shall see, however, that the word may be older. Slim is borrowed from Dutch and comes from the Middle Dutch or Middle Low German slim or slem, where the word meant slanting or crooked. And oddly, English use of the word has always been “gracefully slender,” with a positive connotation. While in Dutch the word has both positive and negative connotation, and in modern German, its counterpart schlimm means bad or wicked.
