Segue is a term used in literature and film to refer to a transition from one topic to another. It is often used to connect two related topics or ideas, and is usually indicated by the phrase 'speaking of which...' For example, if someone was talking about their favorite type of music, they might say 'speaking of which, I also really like jazz.' In this context, 'SEGUE' would be the five-letter answer to the crossword clue.
