What does paradox mean and what's an example?

A paradox is a statement that may seem contradictory but can be true (or at least make sense). This makes them stand out and play an important role in literature and everyday life. Beyond that, they can simply be entertaining brain teasers.

Example:

For example, a character who is both charming and rude might be referred to as a “paradox” even though in the strict logical sense, there's nothing self-contradictory about a single person combining disparate personality traits.

A phrase or statement that is hard to believe because 2 opposite facts are placed in the statement.

Example : Save money by spending it.

This is a paradox because you cannot save money by spending it. You are removing money from your account which leads to a decrease in money.
