* Separate and distinct: Like individual points on a graph or separate data points.
* Not continuous: Meaning it has clear boundaries and doesn't smoothly transition into something else.
While you can't directly call a person "discrete" in the same way you'd describe a mathematical concept, you *could* use "discrete" figuratively to describe someone who:
* Keeps to themselves: "She's a very discrete person, she never talks about her personal life."
* Is careful with information: "He was very discrete about his plans, only sharing them with a select few."
* Has a clear sense of boundaries: "She was very discrete about her space, always keeping a certain distance from others."
However, it's generally not considered a common way to describe someone's personality or behavior. You might use other words like "reserved," "private," "secretive," or "independent" to convey similar meanings.
