Murray's Rule 16

• Murray ignores the fact that multiple negatives are used for emphasis. The more negatives in a sentence, the more emphatically negative the meaning is. For example, “Nor do not saw the air too much with your hand ...” (Hamlet's advice to the players)

• Compare also: He never said nothing to nobody (modern nonstandard English)

• Murray's exclusion of double negatives institutionalized them as nonstandard

Murray on the Use of Auxiliary Verbs 

• Will, in the first person singular and plural, intimates resolution and promising: in the second and third person, only foretells....

• Shall, on the contrary, in the first person, simply foretells; in the second and third persons, promises, commands, or threatens.

• The following passage is not translated according to the distinct and proper meanings of the words shall and will:

• It ought to be, “Will follow me;” and “I shall dwell”
