  NationMaster - Encyclopedia: Affirming a disjunct
Affirming a Disjunct is a non-validating form of argument when "or" is inclusive (see below), as it is standardly interpreted in propositional logic.
As with other propositional fallacies, an argument which affirms a disjunct is most likely to seem valid when we take into consideration some further information not explicitly mentioned in the argument.
The exclusive disjunction of propositions A and B is usually called A xor B, where "xor" stands for "exclusive or" and is pronounced "eks-or" or "zor".

 Disjunct (linguistics) Encyclopedia
In linguistics, a disjunct is a type of adverbial adjunct that expresses information that is not considered essential to the sentence it appears in, but which is considered to be the speaker's or writer's attitude towards, or descriptive statement of, the propositional content of the sentence.
More generally, the term disjunct can be used to refer to any sentence element that is not fully integrated into the clausal structure of the sentence.
A specific type of disjunct is the sentence adverb (or sentence adverbial), which modifies a sentence, or a clause within a sentence, to convey the mood, attitude or sentiments of the speaker, rather than an adverb modifying a verb, an adjective or another adverb within a sentence.

The rule that covers the relation between conjunction and disjunction is simply this: The denial of a conjunction is equivalent to (equal to) a disjunction of the denials of the propositions.
And, the denial of a disjunction is equivalent to a conjunction of the denials of the propositions.
The rule is: An implication is equivalent to a disjunction consisting of the denial of the antecedent as one disjunct and the consequent of the implication as the other disjunct.

The order of the disjuncts does not matter (the meaning of a disjunction stays the same if one switches the disjuncts), so unique names for each position is unnecessary (unlike the hypothetical proposition with its antecedent and consequent).
A disjunctive syllogism consists of a disjunction for the first premise and a premise which either affirms or denies a disjunct.
The reason affirming a disjunct and then denying the other disjunct in the conclusion seems to work is that sometimes the word "or" is used in an exclusive sense.

 Logic Notes
The disjunctive syllogism is a valid argument with two premises and a conclusion.
One of the premises is a disjunction, i.e., of the form ‘either p or q.’ The other premise is the denial or negation of one of the disjuncts.
This is the inclusive sense of the disjunction.
