What fundamentally distinguishes the connective and disjunctive kinds?

Conditional Propositions: Connectives, Disjunctions and Their Main Kinds

• A connective relates an antecedent to a consequent; a disjunctive concerns exclusion between alternatives
• A connective has one word; a disjunctive has two
• Neither can involve truth or falsehood
• No complete proposition can occur in a disjunction
