Elbow grease is an idiom for manual labor and/or the process of working hard to accomplish an objective. [1]
The earliest evidence of the phrase in print was in 1672. [2] Andrew Marvell, an English metaphysical poet, used the words in a satirical book about English parliament. Marvell wrote: "Two or three brawny Fellows in a Corner, with mere Ink and Elbow-grease, do more Harm than an Hundred systematical Divines with their sweaty Preaching." [3]
Further uses are attested in the 1670s. [4] In 1699, the phrase appeared in the New Dictionary of the Canting Crew defined as "a derisory Term for Sweat". [5]
