Baig, also commonly spelled Beigh, Beg, Bey or Begh (Persian: , Bay, Turkish: Bey) was a title which is today used as a name to identify lineage. It means Chief or Commander and is common in South Asia, Turkey, Iran, the Caucasus, Central Asia and Southeastern Europe and among their respective diaspora.
The origin of beg is still disputed, though it is mostly agreed that it is a loan-word. Two principal etymologies have been proposed. The first etymology is from a Middle Iranian form of Old Iranian baga; though the meaning would fit since the Middle Persian forms of the word often mean "lord," used of the king or others. The second etymology is from Chinese po "eldest (brother), (feudal) lord". Gerhard Doerfer seriously considers the possibility that the word is genuinely Turkish. Whatever the truth may be, there is no connection with Turkish berk, Mongolian berke "strong" or Turkish bögü, Mongolian böge "wizard, shaman."
It was also used during the Qing dynasty in China. When the Qing dynasty ruled Xinjiang, it permitted the Turkic Begs in the Altishahr region to maintain their previous status, and they administered the area for the Qing as officials. High-ranking Begs were allowed to wear the Queue.

For the Persian use, it is common to see the name Beg added to the Persian suffix of 'zada' (male), 'zadi' (female), which means 'son of' or 'daughter of'. For Example: Mirza Begzada or Noor Begzadi. For the Turkish use, it is most common to see the spelling Beg or Bey utilized. (Sometimes, it is used along with the title "Mirza", similar to the Mughal usage)..
For the Mughal dynasty use, the honorific title Mirza (Persian: ?) was added before the given name for all the males and 'Baig' (Persian: ) for the males or Begum (Persian: ?) for the females, was added as a family name. For example: Mirza Abdullah Baig or Farzana Begum. This was the historical naming convention for the descendants of the Mughal dynasty, Today, however, it is common to see descendants of the Mughals use Baig as a middle name and Mirza as the surname or vice versa. For example: Abdullah Baig Mirza or Abdullah Mirza Baig.
For the Slavic or Bosniak use, it is common to see the name Beg added to the Slavic suffix of 'ovic', 'ovich', which roughly means 'descendant of'. While the title "Beg" is not in use in Bosnia anymore, track of families of "Beg" descent is kept. But a surname containing "-begovi?" suffix in itself is not a clear indicator of descent. For example, there is a number of "Begovi?" families, some are of noble descent, some not. "Idrizbegovi?" would be another example of a non-noble family with the suffix. Some examples of "beg" families areahbegovi?, Rizvanbegovi?, ?a?irbegovi?. On the other hand, "Kukavica" is an example of a famous "beg" family, not containing the title in itself. The book by Enver Imamovi? "Porijeklo i pripadnost stanovni?tva Bosne i Hercegovine" details the origin of a big number of families in Bosnia and Herzegovina.
There are various other alternative spellings used today as well, such as: Begh, Begg, Beigh, Beyg, Bayg, Bek, Bik.
