The workplace, business, or trade practices associated with buying and selling hides and animal skins.
From 'fellmonger' with the suffix '-y' or '-ery,' which creates nouns describing locations or practices. The '-ery' ending was extremely productive in English for creating words like 'bakery' and 'brewery.'
Notice how English takes one word—'fell' (hide)—and spawns an entire word family: fellmonger, fellmongered, fellmongering, fellmongery—each with slightly different meanings but all related to the same trade!
