Spanish town of
Tarifa is sometimes credited with being the origin of the word "
tariff", since it was the first port in history to charge merchants for the use of its docks. The name "Tarifa" itself is derived from the name of the
Tarif ibn Malik. However, other sources assume that the origin of tariff is the
Italian word tariffatranslated as "list of prices, book of rates", which is
derived from the
Arabicta'rif meaning "making known" or "to define".
