Sheikh (pronounced /ʃeɪk/ SHAYK or /ʃiːk/ SHEEK; Arabic: شيخ šayḫ [ʃæjx], mostly pronounced [ʃeːx/ʃejx], plural شيوخ šuyūḫ [ʃuju:x])—also transliterated Sheik, Shykh, Shaik, Shayk, Shaykh, Cheikh, Shekh, and Shaikh—is an honorific title in the Arabic language. It commonly designates the ruler of a tribe, who inherited the title from his father. "Sheikh" is given to a royal male at birth, whereas the related title "Sheikha" is given to a royal female at birth.
The word in Arabic stems from a triliteral root connected with age and aging: ش-ي-خ, shīn-yā'-khā'. The term literally means a man of vast power, and nobility, and it is used strictly for the royal families of the Middle East. The title carries the meaning leader, elder, or noble, especially in the Arabian Peninsula within the Tribes of Arabia, where shaikh became a traditional title of a Bedouin tribal leader in recent centuries. Due to the cultural impact of Arab civilization, and especially through the spread of Islam, the word has gained currency as a religious term or general honorific in many other parts of the world as well, notably in Muslim cultures in Africa and Asia.
