A name that means something.
E"Prince, commander, leader." An Arabic title of authority — the root of the English word "admiral." Used as a given name especially in Turkish and Bosnian families.
Arabic root: ʾ-m-r — أ-م-ر, to command
"Emir" is the Turkish/Bosnian spelling; "Amir" is Arabic-standard. Both are used in the US — Amir is more common overall but Emir is rising fast, often as a Turkish-American choice.
