The term "discreet" generally refers to being careful and circumspect in one's speech or actions, especially to avoid causing offense or attracting attention. It suggests a level of tact and sensitivity in handling delicate situations or information.
For example, a discreet person might choose to keep a confidence private or to handle a sensitive topic without drawing too much attention. It is often associated with qualities like prudence and discretion.
It's worth noting that "discrete," spelled with a "t," is a different term that refers to separate or distinct entities, commonly used in mathematics and science to describe individual, unconnected units.
