[ f&rm ] (adjective.) 14th century. From German Firma (“business", "name of business”), from Italian firma (“signature”), from firmare (“to sign”), from Latin firmare (“to make firm", "to confirm (by signature)”), from firmus (“firm", "stable”); possibly conflated with Medieval Latin firma (“farmed office, source of revenue”), from Old English feorm (“food, rent, tribute”).
