Whither - wither
From Hull AWE
- The verb 'to wither' was first used of plants, and means 'to dry up', 'to shrivel away', 'to go towards death or die from lack of water'. It has often been extended to other forms of ageing in animals and humans, particularly in the direction of drying up, becoming wrinkled, etc.; it is applied to 'fading away', 'gently declining' and 'losing youthful vigour'.
- The archaic wh- word whither means 'to what place', 'to where', 'in which direction'. It may be an interrogative, as in "Whither goest thou?" (~'where are you going?'); an adverb, as in "Wandering they knew not whither ([~to] where)" (Dickens Old Curiosity Shop, 1841, i. xii. 156, cited OED); or a relative pronoun, as in 'London, whither (~'to which', 'where') I am going tomorrow'. See also where - whence - whither.
