There is no universally accepted standard in the West for transliterating Arabic words and names into English, so bin Laden's name is spelled in many different ways. The version translation most often used by English-language mass media is Osama bin Laden. Most American government agencies, including the FBI and CIA, use either "Usama bin Laden" or "Usama bin Ladin", both of which are often abbreviated to UBL. Less common renderings include "Ussamah Bin Ladin" and "Oussama Ben Laden" (French-language mass media). The last two words of the name can also be found as "Binladen" or (as used by his family in the West) "Binladin". The spelling with "o" and "e" comes from a Persian-influenced pronunciation used in Afghanistan where he lived for a long time.
Strictly speaking, Arabic linguistic conventions dictate that he be referred to as "Osama" or "Osama bin Laden", not "bin Laden", as "Bin Laden" is not used as a surname in the Western manner, but simply as part of his name, which in its long form means "Osama, son of Mohammed, son of 'Awad, son of Laden". Still, "bin Laden" has become nearly universal in Western references to him.
