We propose nested words to capture models where there is both a natural linear sequencing of positions and a hierarchically nested matching of positions. Such dual structure exists for executions of structured programs where there is a natural well-nested correspondence among entries to and exits from program components such as functions and procedures, and for XML documents where each open-tag is matched with a closing tag in a well-nested manner.
