churn: [OE] It has been speculated that the term churn is based on the granular appearance cream takes on as it is stirred or agitated. The Old English noun cyrin comes from a prehistoric Germanic *kernjōn, which may be related to English corn and kernel and Latin grānum ‘grain’. The derived verb churn is a comparatively late creation, not appearing until the 15th century. => corn, grain, kernel
