When I use a word,” Humpty Dumpty said, in rather a
  scornful tone, “it means just what I choose it to mean
  —neither more nor less.” “The question is,” said Alice, 
  “whether you can make words mean so many different 
  things.” “The question is,” said Humpty Dumpty, “which 
  is to be master—that’s all.”
