Though “discreet” and “discrete” look and sound similar, the minor difference in spelling represents a major difference in definition. Both stem from the Latin word “discretus,” meaning “to separate,” but one refers to being cautious, while the other refers to something that is individual and separate.

How to Use Discreet

An adjective, “discreet” means self-restrained, prudent, cautious, or tactful, and often is used in reference to speech. It is something that is done under the radar, and is unlikely to get attention or cause offense. It can be used to describe someone who is private and cautious, or who understands the consequence of sharing certain or private information. We might ask if someone is discreet, meaning we can trust them to not share information we would prefer to keep private. The noun forms are “discretion” and “discreetness.”

How to Use Discrete

Also an adjective, “discrete” means individual, detached, or separate. It is often used less than “discreet,” and is generally more technical. The noun form is “discreteness.”

How to Remember the Difference

It’s no surprise that the two homonyms are the subject of so much confusion: they both emerged in the 14th century, but “discrete” fell out of common usage for about 200 years—though its spelling didn't. Those writing “discreet” spelled it in a variety of ways, including “discrete,” “discreet,” “dyscrete,” and “discreete.” The difference between the two spellings only became popularized in the 16th century, when both ways of spelling and meanings became more defined.

Remember the difference by thinking of the placement of the “e”s in both. Unlike in discreet, in discrete, they are separate, and “discrete” means separate or detached.
