When we say all men, no men, the term men is said to be distributed, i.
e. it is applied to everyone who belongs to the class, while when we say
some men it is undistributed, not applied to everyone. In this the
original sense of the word singulars are incapable of distribution, and
so pronounced by Petrus Hispanus. Nevertheless, in many modern logical
works they are said to be distributed (by myself among others) as being
of necessity used in their whole extension.
