1. Idea or Concept: This is the most common usage. A notion is a thought, idea, or belief. It's something you think about or have an opinion on.
* Example: "I had a notion to visit my grandmother." (This means the speaker had a sudden thought or idea to visit their grandmother.)
* Example: "The notion of time travel is fascinating." (This refers to the idea of time travel itself.)
2. Opinion or Belief: Notion can also refer to a personal opinion or belief, often a vague one.
* Example: "I have a notion that it's going to rain today." (This implies a personal belief, not necessarily based on solid evidence.)
3. A Small Amount: In some contexts, "notion" can mean a small amount or quantity. This is less common and primarily used in older language.
* Example: "He had a notion of money in his pocket." (This means he had a small amount of money.)
4. Notion as a Software: Notion is also a popular software application used for note-taking, project management, and knowledge management.
To clarify the meaning of "notion", you need to look at the context in which it is used.
