screwdriver

the word 'screwdriver' is a transparent compound noun formed from two english words. the first element, 'screw', has a complex history, likely entering english via old french from a latin source, originally referring to a cylindrical fastener with a helical ridge. the second element, 'driver', derives from the old english verb 'drīfan', meaning to propel or force forward, with the '-er' suffix creating an agent noun. the compound logically names a tool designed to drive screws. the later, metaphorical application to a cocktail humorously suggests the drink's potency or its function as a mixer.

Structure: screw (fastening device) + driver (tool that applies force) - screw: from middle french escroue, of uncertain origin, possibly from latin scrofa (a sow, perhaps from the shape of a screw thread). functions as the object noun in the compound. - driver: from old english drīfan (to drive, force, pursue). the agent noun suffix -er indicates a thing that performs an action. functions as the agent/tool noun in the compound.
