Etymology and Origin of definition of churn
The word churn traces back to Old English circa the 8th to 11th century, from the verb cyrin or cyrn, meaning to turn or grind. Its roots are Germanic, related to Old High German kerna, which also suggests rotation and grinding.
Originally it was very literal, tied to the wooden device known as a churn used for making butter. Over centuries the image of repetitive motion shifted into figurative uses around change and turnover.
