1. Navigation Tool: This is the most common meaning. A compass is a device that uses a magnetic needle to indicate direction, usually north. It's essential for navigation, especially when landmarks or other visual cues are unavailable.
2. Scope or Range: This meaning refers to the limits or boundaries of something. For example:
* "The scope of her research was very broad." (meaning the topics she studied were wide-ranging)
* "The compass of our discussion should be limited to environmental issues." (meaning we should only talk about environmental issues)
The specific meaning of "compass" will depend on the context in which it is used.
