When do you use erred or errored?

Answer 1

"Erred" is the traditional past tense of the verb "to err," meaning to make a mistake, and is often used in formal writing. "Errored" is a more modern, informal alternative that has emerged, particularly in technical contexts, such as computer programming, where it describes an operation that has encountered an error. While both forms are understood, "erred" is generally preferred in standard English.
