the word 'stuffed' originates from the verb 'stuff', which entered middle english from old french 'estoffer', meaning to equip or furnish. this old french term has germanic roots, likely connected to the old english 'stopian', which carried the sense of blocking or filling a hole. the '-ed' suffix is the common germanic past participle marker, used here to create an adjective describing a state resulting from the action of filling. thus, the literal meaning of "having been filled" evolved into its modern senses, ranging from describing a packed object and a taxidermied animal to the colloquial feeling of being overly full from eating.

Structure: stuff (to fill) + ed (adjective suffix) stuff (from old french 'estoffe', meaning material, supplies; of germanic origin, related to old english 'stopian', to stop up, block). ed (old english past participle suffix '-ed', '-od', '-ad', used to form adjectives from verbs or nouns).
