mulish

the word "mulish" is a straightforward english formation, combining the noun "mule" with the adjectival suffix "-ish." the mule, a pack animal known since antiquity for its perceived obstinacy and resistance to being driven, provides the core semantic element. the suffix "-ish," of germanic origin, is commonly used to denote possession of a particular quality, as in "childish" or "foolish." therefore, "mulish" literally means "having the qualities of a mule," with its modern abstract meaning of extreme stubbornness deriving entirely from the stereotypical behavior attributed to the animal.

Structure: mule (the animal) + ish (adjective suffix) mule: from latin mūlus, meaning a hybrid offspring of a male donkey and a female horse, noted for its stubbornness. ish: from old english -isc, a suffix forming adjectives meaning "having the qualities or characteristics of."
