Sir in the context of "Ladapo Ademola"

Bey, also spelled as Baig, Bayg, Beigh, Beig, Bek, Baeg, Begh, or Beg, is a Turkic title for a chieftain, and a royal, aristocratic title traditionally applied to people with special lineages to the leaders or rulers of variously sized areas in the numerous Turkic kingdoms, emirates, sultanates and empires in Central Asia, South Asia, Southeast Europe, and the Middle East, such as the Ottomans, Timurids or the various khanates and emirates in Central Asia and the Eurasian Steppe. The feminine equivalent title was begum. The regions or provinces where "beys" ruled or which they administered were called beylik, roughly meaning "governorate" or "region" (the equivalent of a county, duchy, grand duchy or principality in Europe, depending on the size and importance of the beylik). However the exact scope of power handed to the beys varied with each country, thus there was no clear-cut system, rigidly applied to all countries defining all the possible power and prestige that came along with the title.

Today, the word is still used formally as a social title for men, similar to the way the titles "sir" and "mister" are used in the English language. Additionally, it is widely used in the naming customs of Central Asia, namely in countries such as Uzbekistan, Kazakhstan and Kyrgyzstan. Notably, the ethnic designation of Uzbeks comes from the name of Öz Beg Khan of the Golden Horde, being an example of the usage of this word in personal names and even names of whole ethnic groups. The general rule is that the honorific is used with first names and not with surnames or last names.

A courtesy title is a title that does not have legal significance but is rather used by custom or courtesy, particularly, in the context of nobility, the titles used by children of members of the nobility (cf. substantive title).

In some contexts, courtesy title is used to mean the more general concept of a title or honorific such as Mr., Mrs., Ms., Miss, Madam, Sir for those who not been awarded a knighthood or a baronetcy, as well as Dr. for physicians who have not actually achieved a doctorate.

Sir Hari Singh Bahadur GCSI GCIE GCVO (September 1895 – 26 April 1961) was the last ruling Maharaja of the princely state of Jammu and Kashmir of the Dogra dynasty.

Hari Singh was the son of Amar Singh and Bhotiali Chib. In 1923, following his uncle's death, Singh became the new Maharaja of Jammu and Kashmir. After Indian Independence in 1947, Singh wanted Jammu and Kashmir to remain as an independent kingdom. He acceded to the Dominion of India to get the support of Indian troops against an invasion by tribal armed men and the Pakistan Army into his state. Singh remained the titular Maharaja of the state until 1952, when the monarchy was abolished by the Indian government. After spending his final days in Bombay, he died on 26 April 1961.

The T–V distinction is the contextual use of different pronouns that exists in some languages and serves to convey formality or familiarity. Its name comes from the Latin pronouns tu and vos. The distinction takes a number of forms and indicates varying levels of politeness, familiarity, courtesy, age or even insult toward the addressee. The field that studies and describes this phenomenon is sociolinguistics.

Many languages lack this type of distinction, instead relying on other morphological or discourse features to convey formality. English historically contained the distinction, using the pronouns thou and you, but the familiar thou largely disappeared from the era of Early Modern English onward, with the exception of a few dialects. Additionally, British commoners historically spoke to nobility and royalty using the third person rather than the second person, a practice that has fallen out of favour. English speakers today often employ semantic analogues to convey the mentioned attitudes towards the addressee, such as whether to address someone by given name or surname or whether to use sir or madam. Under a broader classification, T and V forms are examples of honorifics.

In the British honours system, the title of Knight Bachelor is the basic rank granted to a man who has been knighted by the monarch but not inducted as a member of one of the organised orders of chivalry.

Knights Bachelor are the most ancient sort of British knight (the rank existed during the 13th-century reign of King Henry III), but Knights Bachelor rank below knights of chivalric orders. A man who is knighted is formally addressed as "Sir [First Name] [Surname]" or "Sir [First Name]" and his wife as "Lady [Surname]".

The Royal Air Force's Strike Command was the military formation which controlled the majority of the United Kingdom's bomber and fighter aircraft from 1968 until 2007 when it merged with Personnel and Training Command to form the single Air Command. It latterly consisted of two formations – No. 1 Group RAF and No. 2 Group RAF. The last Commander-in-Chief was Air Chief Marshal Sir Joe French.
