Negation refers to the situation in which something is said not to be the case. In propositional logic, it is the logical operation which turns the truth value of a proposition into its opposite. Proposition Neg phi is true if and only if phi is not true:

(i)	phi		Neg phi
 	 1		   0
	 0		   1

The negation operator Neg is a unary connective. In syllogistic logic, negation can be an operator on terms. Thus in nobody is ill, the term nobody is considered the negation of somebody.
