- In British literature and historical texts, rumour has been used consistently for centuries.
- American English simplified many British spellings over time, leading to rumor.

A rumour or rumor is unverified information that spreads from person to person, often about events, people, or situations. It does not guarantee truth and can sometimes be false or misleading.
Key Points:

- May influence opinions, actions, or decisions before verification.
