Forgets to proorfeed, say

ERRS

Think of a short word that describes making small mistakes, like slipping up while typing or missing a step in a task.

The clue plays on the idea of making a mistake while proofreading. "Forgets to proorfeed" sounds like a typo for "proofread," hinting at an error. The word "ERRS" means "makes mistakes," which fits both the definition and the pun—since missing the "f" in "proofread" is itself an error. The surface meaning and wordplay work together to point to the answer.
