What word means to turn away from the main topic of a conversation?

The term "digress" is used to describe the action of temporarily straying from the main topic of discussion. When someone digresses in a conversation, they may introduce an unrelated subject or provide additional information that diverges from the primary focus. This often happens in casual conversations or presentations when a speaker goes off on a tangent, whether to elaborate on a point or share a related anecdote. The essence of digression is that it moves away from the intended path of discussion, hence fulfilling the requirement of the question.
