Read the FAQ explanation of Comprehensible InputReal Context
Annul is a formal verb meaning to declare something invalid or legally void; to cancel or revoke a law, contract, or agreement so that it has no legal effect. The nuance is that annulment removes the consequence entirely, not merely suspends it. It is often used in legal contexts for contracts, marriages in some jurisdictions, treaties, decrees, licenses, or votes where the entry is treated as if it never existed. The etymology traces to Latin an- (without) + nullus (nothing); it traveled through Old French into Middle English. A common memory image is tearing a contract in half to erase all obligations. In professional writing, use annul for formal revocation; for everyday talk, cancel or void may be more natural depending on the domain.
Usage Reminders
- Use in formal or legal contexts only
- Avoid casual speech about rights or obligations
- Compare with cancel and void to choose the most precise sense
- Usually followed by the object being annulled (the contract was annulled)
- Passive voice common: The contract was annulled by the court
Common Misconceptions
- Annul = cancel in all contexts
- Annul means to delay a decision
- Annul is the same as void
- Annul applies only to marriages
- Annul is informal
Thinking Differences
Learners often assume annul is interchangeable with cancel in everyday speech, but in English it tends to be used in solemn, legal, or formal texts about removing legal rights or obligations.
Learning Tips
- Study formal vs informal usage
