Definition
Donnish describes someone who resembles a college don or academic in manner and appearance. It often implies a slightly old-fashioned, studious, and perhaps even pedantic demeanor. Think of someone with tweed jackets, elbow patches, and a penchant for lecturing. Donnish behavior can sometimes be perceived as arrogant or overly intellectual. It suggests a deep immersion in academic life, sometimes to the exclusion of other interests. The image conjures a person deeply invested in their studies.
