Syn. Forgetfulnes, Oblivion.
Forgetfulness is Anglo-Saxon, and oblivion is Latin. The former commonly has reference to persons, and marks a state of mind; the latter commonly has reference to things, and indicates a condition into which they are sunk. We blame a man for his forgetfulness; we speak of some old custom as buried in oblivion. But this discrimination is not strictly adhered to.
