To sidetrack is to veer off a straight path, or to cause something (or someone) to do so. The smell of a rabbit in the woods might sidetrack your dog from coming when you call him.

In addition to literally wandering off course, sidetrack can also be used figuratively, when someone gets distracted from a task or focus, like when your text messages sidetrack you from finishing your homework. You can sidetrack a conversation, too, by controlling it and steering it in a new direction: "She always sidetracks the conversation so we end up talking about television."
