Synonyms: cause, reason, occasion, antecedent
These nouns denote what brings about or is associated with an effect or result. A cause is an agent or condition that permits the occurrence of an effect or leads to a result: "He is not only dull in himself, but the cause of dullness in others" (Samuel Foote).
Reason refers to what explains the occurrence or nature of an effect: There was no obvious reason for the accident.
Occasion is something that brings on or precipitates an action, condition, or event: "Injustice provides the occasion for change" (Alan Dershowitz).
Antecedent refers to what has gone before and implies a relationship—but not necessarily a causal one—with what ensues: Some of the antecedents of World War II lie in economic conditions in Europe following World War I.
