noun, feminine/fiʁm/plural: firmes
firm (company)
Borrowed from English firm (“commercial undertaking, corporate name”) and/or German Firma (“business, business name, signature”), both from Italian firma (“signature”), from firmare (“to sign”), from Latin firmō (“to make firm”); possibly conflated with Medieval Latin firma (“farmed office, source of revenue”), from Old English feorm (“food, rent, tribute”). More at firm, farm.
