A segue is a smooth transition between two things, like music or ideas.
You know how sometimes you're listening to an album and one song just flows into the next without any loud noises or awkward pauses? That's what a segue sounds like - it's a connection that makes things seem less jarring. People also use the word when talking about presentations or speeches: "The speaker had a nice segue from discussing taxes to talking about the economy." It means they smoothly moved their ideas along, making it easy for the audience to follow.
An instance of segueing, a transition.
To move smoothly from one state or subject to another.
Example: I can tell she’s going to segue from our conversation about school to the topic of marriage.
