Is there a term that describes the phenomenon where a term with a once literal and direct meaning is carried on or borrowed to refer to something that is either only remotely related or completely unrelated to the original meaning? Or rather, is there a term for a class of words such as these that have been orphaned, so to speak, from their original meanings? (Something that would satisfy the statement 'The terms 'carriage return', 'line feed', and 'dashboard' are all _______s.')
