Today’s idiom: against the grain
Meaning: doing something that is not the norm
Origin: Both sources agree that the above phrase was made popular by Shakespeare in Coriolanus, written in the early 1600’s. It is not clear if he was referring to the grain one would find in wood, though it does appear that he is instrumental in word “grain” referencing one’s nature. In 1650 Thomas Hubbert, in A pill to purge formality, used the phrase again.
