"He has found the meaning. / But I will gloze with him."
-- William Shakespeare, Pericles, Prince of Tyre, 1608
A claim thus livingly acknowledged is acknowledged with a solidity and fullness which no thought of an "ideal" backing can render more complete; while if, on the other hand, the heart's response is withheld, the stubborn phenomenon is there of an impotence in claims which the universe embodies, which no talk about an eternal nature of things can gloze over or dispel.
-- William James, The Moral Philosopher and the Moral Life, 1891
Gloze came to English in the 1200s and finds its roots in the Medieval Latin glossāre.
