Did you know?

Moiety is one of thousands of words that English speakers borrowed from French. The Anglo-French moité (meaning "a half" or "part of something") comes from Late Latin medietat-, meaning "a half." Around the same time that moiety was borrowed from Anglo-French, medietat- was also borrowed directly from Latin as mediety, a word which can also mean "a half." Medietat- comes from Latin medius (meaning "middle"), which has contributed to such English words as medium, meridian, and milieu.
