the word 'tannery' is built upon the old english verb 'tannian', which itself is borrowed from a celtic source, likely related to the oak or fir trees whose bark provided the tannin used in the process. the suffix '-ery', of latin origin via french, is a productive morpheme in english for forming nouns that denote a place of work or manufacture. thus, the term's literal construction means "a place for tanning," directly and logically describing its function. this combination effectively captures the industrial process, evolving from an ancient craft into the modern, specific term for the factory where leather is produced.
