Pretty good examples there, Bill. This one caught my eye:

distinctio
Explicit references to various meanings of a word-usually for the purpose of removing ambiguities.
"If by light you mean 'clear,' I am glad you do see them; if by light you mean of 'no weight,' I am sorry you do not feel them." (Hoskyns)
"It depends on what the meaning of the word is is. If is means 'and never has been,' that is one thing. If it means 'there is none,' that was a completely true statement."
(Bill Clinton, Grand Jury testimony)
