the word "stuffer" is a transparent english compound built from the native germanic verb "stuff" and the agentive suffix "-er." the verb "stuff" itself has a complex journey, entering middle english from old french "estoffer," which meant to equip or furnish, particularly with provisions. this old french term likely has germanic roots, possibly related to "stopfen," meaning to plug or cram. the "-er" suffix is one of the most productive in english, directly inherited from old english "-ere," used to form agent nouns. therefore, a "stuffer" literally means "one who or that which fills or crams," a logic perfectly preserved in its modern meanings, from a person filling poultry to an item filling an envelope.

Structure: stuff (to fill) + er (agent suffix) stuff (from old english 'stoff', meaning material, supplies, with a verb sense developing in middle english from old french 'estoffer', to equip or furnish); er (agentive suffix from old english '-ere', of germanic origin, used to form nouns denoting a person or thing that performs an action).
