Separating; disjoining.

Incapable of union.

In grammar, a disjunctive conjunction or connective, is a word which unites sentences or the parts of discourse in construction, but disjoins the sense, noting an alternative or opposition; as, I love him, or I fear him; I neither love him, nor fear him.

In logic, a disjunctive proposition, is one in which the parts are opposed to each other, by means of disjunctive; as, it is either day or night. A disjunctive syllogism, is when the major proposition is disjunctive; as, the earth moves in a circle, or an ellipsis; but it does not move in a circle, therefore it moves in an ellipsis.

A word that disjoins, as or, nor neither.
