Censor or Sensor – Quick Answer
Censor means to remove, block, or suppress content that is considered offensive, harmful, or sensitive.
Example: The government may censor violent scenes on TV.
Sensor means a device that detects or measures something like light, heat, motion, or sound.

👉 Simple rule:

The Origin of Censor or Sensor
Censor comes from the Latin word censor, an official in ancient Rome who judged public morals and behavior. Over time, it came to mean controlling or limiting information.
Sensor comes from the Latin word sensus, meaning “feeling” or “perception.” It later became a scientific term for instruments that detect physical changes.
The confusion exists because both words:
- Sound similar
- Share Latin roots
- Are common in modern media and technology
But historically, they developed for very different purposes.
