For this Grammar Rules post, let's take a look at when to use errand, errant, and arrant. An "a" or "e" here and a "d" or "t" there, and you've got completely different words and meanings. So let's see when something (or someone) is an errand, errant, or arrant.

Errand vs. Errant vs. Arrant

Errand is a noun that can refer to a trip taken to attend to a matter of some sort (like paying a bill or shopping for groceries), or it can refer to the actual matter of some sort.

Errant, on the other hand, is an adjective that describes the action of straying outside the expected path, range, or standard. It can also describe someone or something that moves aimlessly and/or without an obvious pattern (from an errant child to an errant wind).

Arrant is an adjective that describes being or acting without any moderation. A person might be called an arrant fool, knave, or dummy-head.
