Coda

Coda: The coda is ending, as in the final part of a music composition or a story. A funeral is the coda to someone's life, and Nixon's resignation was the coda of his political career. It is a Latin word meaning tail and shares it etymology with caudal, an adjective referring the the tail or tail area.

From the time I turned five years old, I had a coda for the end of my prayers at night: Please don't let Mommee and Daddy get divorced.
