Neither (1) nor (2) alone is sufficient for (3) to hold.
Thus A is neither symmetric nor positive.
Both X and Y are countable, but neither is finite.
Neither of them is finite.
[Use neither when there are two alternatives; if there are more, use none.]
Let u and v be two distributions neither of which has compact support.
As shown in Figure 3, neither curve intersects X.
In neither case can f be smooth. [Note the inversion after the negative clause.]
Both proofs are easy, so we give neither.
Thus X is not finite; neither <nor> is Y.
Neither is the problem simplified by assuming f=g.
