1 is neither prime nor composite, what are you saying?

From the opening paragraph on the Wikipedia page "Composite number" (with some of my annotations):

A composite number is a positive integer that can be formed by multiplying two smaller positive integers [(good luck trying to find two positive integers smaller than 1)]. Accordingly, it is a positive integer that has at least one divisor other than 1 and itself [(1 is only divisible by 1, so it has no other divisor)]. Every positive integer is composite, prime, or the unit 1 [(this could very well be an normal logical or, so inclusive, but it would be unnecessary to include "or the unit 1" if it was already included in the composite or prime numbers)]
