hipped

The word 'hipped' is a straightforward English formation from the noun 'hip'. Its architectural sense, describing a roof with slopes on all sides, directly derives from the concept of the hip as a projecting angle or joint, metaphorically transferred to the angled junction of roof planes. The informal sense of being obsessed or overly enthusiastic emerged in the 20th century, likely influenced by the idea of being 'seized' or 'caught' by something, much as the hip is a pivotal point of the body. Both meanings showcase the productive nature of the common adjectival suffix -ed in creating descriptive terms based on a core noun.
