Past tense: departed from the main subject or line of discussion; went off on a tangent.
From Latin 'digredi' (to depart, go away) + past tense '-ed'. The verb 'digress' entered English in the 1600s from Latin, becoming standard in educated speech.
Everyone digresses—it's so natural that our brains literally can't help it—and linguists say digression actually helps us understand context better by connecting seemingly unrelated ideas.
