"Mukataa" is an Arabic word that refers to a tax collection system which was implemented during the Ottoman Empire. It was applied on agricultural lands and crops, and the tax collector was often referred to as a "muktar". Some possible synonyms for "mukataa" could include "taxation", "imposition", "levy", "tariff", "tribute", "assessment", or "duty". These terms all refer to some form of financial obligation or burden placed on individuals or entities. However, "mukataa" specifically refers to the Ottoman system of taxation, so other possible synonyms might be more culturally specific, such as "timar" or "vaka".
