The English term tariff derives from the French: tarif, lit. 'set price' which is itself a descendant of the Italian: tariffa, lit. 'mandated price; schedule of taxes and customs' which derives from Medieval Latin: tariffe, lit. 'set price'. This term was introduced to the Latin-speaking world through contact with the Turks and derives from the Ottoman Turkish: تعرفه, romanized: taʿrife, lit. 'list of prices; table of the rates of customs'. This Turkish term is a loanword of the Persian: تعرفه, romanized: taʿrefe, lit. 'set price, receipt'. The Persian term derives from Arabic: تعريف, romanized: taʿrīf, lit. 'notification; description; definition; announcement; assertion; inventory of fees to be paid' which is the verbal noun of Arabic: عرف, romanized: ʿarafa, lit. 'to know; to be able; to recognise; to find out'.[13][14][15][16][17][18]
