: What does 'go off on a tangent' mean?

Regarding conversation, it means talk off topic. The person is talking about Subject 1 and gets distracted and starts talking about Subject 2. Or if a person is housecleaning, finds a box of old pictures and abandons the original job to research the photos, that's going off on a tangent. Tangent means "diverging from an original purpose or course" (Merriam-Webster).
