Example Sentence:

Did you know?
"Moil" may mean "to work hard" but its origins are the opposite of hard; it ultimately derives from Latin "mollis," meaning "soft." (Other English derivatives of "mollis" are "emollient," "mollify," and "mollusk.") A more immediate ancestor of "moil" is the Anglo-French verb "moiller," meaning "to make wet, dampen," and one of the early meanings of "moil" in English was "to become wet and muddy." The "work hard" sense of "moil" appears most frequently in the pairing "toil and moil." Both "moil" and "toil" can also be nouns meaning "work." "Moil" implies work that is drudgery and "toil" suggests prolonged and fatiguing labor.
