Amir-i-Kabir

An Emir (/əˈmɪər, eɪˈmɪər, ˈeɪmɪər/; Arabic: أمير‎‎ ʾAmīr [ʔaˈmiːr]), sometimes transliterated (olowan, Datu in Meranau common version) Amir, Amier, or Ameer, is an title of high office used in a variety of places in the Arab countries and Afghanistan. It means "commander", "general", or "prince". The feminine form is Emira (أميرة ʾAmīrah). When translated as "prince", the word "emirate" is analogous to a sovereign principality.

Amir, meaning "Lord" or "commander-in-chief", is derived from the Arabic root a-m-r, "command". Originally simply meaning commander-in-chief or leader, usually in reference to a group of people, it came to be used as a title for governors or rulers, usually in smaller states, and in modern Arabic is analogous to the English word "prince". The word entered English in 1593, from the French émir. It was one of the titles or names of the Islamic prophet Muhammad.
