Why is it milquetoast, and not milk toast?
Caspar Milquetoast is a comic strip character created in 1924 by cartoonist Harold T. Webster. Beginning a few years after the character’s debut, the term milquetoast came to describe a timid or meek person. Caspar’s last name is fitting because milk toast is a weak, bland concoction of buttered toast served in a dish of warm milk.
