Tuple stands for an entire row; more precisely it stands for a row with a specific set of columns. More like a function for every row. More info: http://www.tomjewett.com/dbdesign/dbdesign.php?page=tables.php

A tuple represents one row of the relational database or a row in the result of a specific query. It is part of the schema, as it simply encapsulates the data.
