An emir (/; Arabic: أمير ʾamīr [ʔaˈmiːr]), sometimes transliterated amir, amier, or ameer, can refer to a king or an aristocratic or noble and military title of high office used in a variety of places in the Arab countries, West Africa, Afghanistan and in the Indian subcontinent. The term has been widely used to denote a "commander", "general", or "leader" i.e. Amir al-Mu'min. The feminine form is emira (أميرة ʾamīrah). When translated as "prince", the word "emirate" is analogous to a sovereign principality. In contemporary usage, the term indicates to some Muslim head of states of Emirates or leaders of Islamic organisations.
Amir, meaning "lord" or "commander-in-chief", is derived from the Arabic root a-m-r, "command". Originally simply meaning "commader”, it came to be used as a title of leaders, governors, or rulers of smaller states. In modern Arabic the word is analogous to the title “Prince". The word entered English in 1593, from the French émir. It was one of the titles or names of the Islamic prophet Muhammad.
