Emily Dickinson Lexicon

DIS-JUNC'TIVE, a.

1. Separating; disjoining.
2. Incapable of union. [Unusual.] – Grew.
3. 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.
4. In logic, a disjunctive proposition, is one in which the parts are opposed to each other, by means of disjunctives; as, it is either day or night. A disjunctive syllogism, is when the major proposition is disjunctive; the earth moves in a circle, or an ellipse; but it does not move in a circle, therefore it moves in an ellipsis. – Watts.
