The idiom "against the grain" refers to doing something that goes against common or typical behavior, opinion, or belief. It describes a situation where someone or something is going against what is generally accepted as right, normal, or appropriate. The phrase may also suggest a certain level of resistance or conflict with prevailing norms.
The idiom "against the grain" dates back to the Middle Ages when people believed that the direction of the grain on barley or wheat stalks could affect their health. As such, doctors and healers recommended consuming foods that were harvested in a way that went against the grain, which included cutting the stalks diagonally instead of straight across. Over time, this belief evolved to refer to anything that was different from what was considered normal or typical. The phrase "going against the grain" emerged in the 19th century and has since been used to describe a wide range of situations where someone or something deviates from social norms or expectations.
