1470-Lex-Bag-Tennyson's-Brook by A Way with Words published on 2017-04-23T20:49:55Z The expression on and on like Tennyson's brook describes something lengthy or seemingly interminable, like a long-winded speaker who goes on and on like Tennyson's brook. The phrase is a reference to a lovely poem by Alfred Lord Tennyson about the course of a body of water. http://waywordradio.org
