The precedence of Thai royalty follows a system of ranks known as ''thanandon'' ( th, ฐานันดร), which are accompanied by royal titles.

The Sovereign

There are two styles which can be used for a king in ordinary speech, depending on whether he has been crowned: *Crowned kings: ''Phra Bat Somdet Phra Chao Yu Hua'' ( th, พระบาทสมเด็จพระ เจ้า; en, His Majesty the King) is the style used in ordinary speech when referring to the kings of Thailand after their coronation. This style may be used in two ways: **Preceding the name of the king; e.g., ''Phra Bat Somdet Phra Chao Yu Hua Phumiphon Adunyadet'' ( th, พระบาทสมเด็จพระเจ้าอยู่หัวภูมิพลอดุลยเดช; His Majesty King

Bhumibol Adulyadej Bhumibol Adulyadej ( th, ภูมิพลอดุลยเดช; ; ; ( Sanskrit: ''bhūmi·bala atulya·teja'' - "might of the land, unparalleled brilliance"); 5 December 192713 October 2016), conferred with the title King Bhumibol the Grea ...

). **More formally it can be split across the name, possibly with the omission (or modification) of the words ''"Phra Chao Yu Hua"''; e.g., ''Phra Bat Somdet Phra Paramintara Maha Phumiphon Adunyadet'' ( th, พระบาทสมเด็จพระปรมินทรมหาภูมิพลอดุลยเดช) and ''Phra Bat Somdet Phra Paramindara Maha

Phra Pokklao Chao Yu Hua'' ( th, พระบาทสมเด็จพระปรมินทรมหาประชาธิปกฯ พระปกเกล้าเจ้าอยู่หัว). *Uncrowned kings: ''Somdet Phra Chao Yu Hua'' ( th, สมเด็จพระเจ้าอยู่หัว), normally preceding the king's name, is restricted to a king who has not yet been crowned. When crowned, he assumes the title of ''Phra Bat Somdet Phra Chao Yu Hua''; e.g., ''Somdet Phra Chao Yu Hua Maha Wachiralongkon Bodinthrathepphayawarangkun'' ( th, สมเด็จพระเจ้าอยู่หัวมหาวชิราลงกรณ บดินทรเทพยวรางกูร; His Majesty King Maha Vajiralongkorn Bodindradebayavarangkun).

Consorts

Traditionally, titles of royal wives depended on their birth titles and royal favour; only princesses of high birth (Chao Fa, Phra Ong Chao and Mom Chao Ying) assuming titles higher than Chao Chom. There were no clear rules about the hierarchy of titles above Chao Chom until the time of King

Mongkut Mongkut ( th, มงกุฏ; 18 October 18041 October 1868) was the fourth monarch of Siam (Thailand) under the House of Chakri, titled Rama IV. He ruled from 1851 to 1868. His full title in Thai was ''Phra Bat Somdet Phra Menthora Ramathib ...

Princes and princesses

Holders of these titles are still considered royal, since they are (at most) two generations removed from a king. ''Nai Luang'' (ในหลวง) is an

for a king. Children of a king are called ''Luk Luang'' ( ลูก หลวง "royal children"), and grandchildren of a king are called ''Laan Luang'' ( หลาน "royal grandchildren"). The concept is similar to the French system of "princes of the blood" and the Iberian system of "infantes." In English, they are normally called "prince" or "princess". Special forms are used when one wishes to address them, although the language is less elaborate than when speaking to the king or the queen. A male Luk Luang who does not accede to the throne would assume a new royal surname, normally reflecting his birth name (as opposed to an

given later). The surname can be used by his wife if she is a commoner by birth, possibly with ''Na Ayudhya'' added if she has no noble title. It is otherwise not normally used until his children (or grandchildren) first hold the title of ''Mom Chao'', when the surname will first appear in their names.

Royal descendants

More distant royal progeny, starting from the children of male Mom Chao, are considered commoners. However, these commoners have titles indicating that their ancestry can be traced back to a king.

Mom Rajawongse

''Mom Rajawongse'' (หม่อมราชวงศ์, ; abbreviated in Thai as ม.ร.ว. and in English as M. R. and translated as "His/Her Excellency") is the title assumed by children of male Mom Chao M.C.(English) M.C. After first name Informally, they may be called Khun Chai (male) or Khun Ying (female) (). Holders of this title are occasionally erroneously referred to as princes or princesses in older English documents; it is now more common to use the correct title, "Mom Rajawongse". If a specific title is appended, sometimes the titular may be called His/Her Grace by proclamation of the King or a Prince-Regent, but not by a Queen-regent or any royal member sitting in the King's capacity as a Councillor-of-State.

Mom Luang

''Mom Luang'' (หม่อมหลวง, abbreviated in Thai ม.ล. and sometimes in English as M. L. and translated as "The Honourable") are the last royal descendants retaining a title. Mom Luang titles are conferred on children of male Mom Rajawongse. Colloquially (although incorrectly), they are sometimes addressed as "Mom"; the correct informal address is "Khun" ().

Na Ayudhya

In the Family Name Act, B. E. 2465,

Rama VI Vajiravudh ( th, วชิราวุธ, , 1 January 188126 November 1925) was the sixth monarch of Siam under the Chakri dynasty as Rama VI. He ruled from 23 October 1910 until his death in 1925. King Vajiravudh is best known for his efforts ...

ordered that royal descendants who do not hold any title should append "Na Ayudhya" (ณ อยุธยา) to their surname to signify they are descended from a royal bloodline. Sometime spelled "Na Ayutthaya".

Wife of prince

Wives of princes have titles, depending on the titles on both sides.

Phra Vorachaya

''Phra Vorachaya'' () is a title of the royal consort of the Crown Prince''. She is elevated to ''Phra Chao Vorawongse Ther Phra Ong Chao''.

Phra Chaya

''Phra Chaya'' () is a princess, ''Chao Fa'' (HRH Princess) or ''Phra Ong Chao'' (HRH Princess) who is married to prince, at every level. She retains her own title. When referring to her as a wife of the prince, she may be called "Phra Chaya Nai (husband's name)".

Chaya

''Chaya (ชายา)'' is a princess or ''Mom Chao'' (HSH Princess) who is married to prince, at every level. Again, she would retain her own title. When referring to her as a wife of the prince, she may be called "Chaya Nai (husband's name)".

Mom

''Mom (หม่อม)'', in this context, is a commoner married to a prince. She uses this title as a prefix of her name, adding ''na Ayudhya'' to her new surname; for example, Mom Srirasmi Mahidol na Ayudhya (a wife of Chao Fa Maha Vajiralongkorn, whose surname is Mahidol). If she has her own title (''Mom Rajawongse'' or ''Mom Luang''), she retains it.

Married princesses

The son of a holder of the following titles generally inherits a title one step below; a female Mom Rajawongse married to a commoner would produce a child with no title. According to the Royal Marriages Act, B. E. 2475, a princess wishing to marry to a commoner must request royal permission and abandon her royal title. For example, if princess Chao Fa, HRH Princess of Thailand, wished to marry a Mom Rajawongse commoner she would lose her royal title (Chao Fa, HRH Princess of Thailand) but retain royal style as follows: * Chao Fa, HRH Princess of Thailand: ''Tunkramom Ying'' (daughter of the sovereign with the queen) ** Tunkramom Ying Ubolratana Rajakanya, formerly ''Somdet Phra Chao Luk Thoe Chao Fa'' Ubolratana Rajakanya * Chao Fa, HRH Princess of Thailand: ''Somdet Ying'' (daughter of the sovereign with the royal consort) * Phra Ong Chao, HRH Princess of Thailand: ''Sadet Phra Ong Ying'' (daughter of the sovereign with the concubine) * Phra Ong Chao, HRH Princess of Thailand: ''Phra Ong Ying'' (daughter of the son of the sovereign with the queen and his royal consort) * Phra Ong Chao, HH Princess of Thailand: ''Than Phra Ong Ying'' (daughter of the son of the sovereign who was elevated from Mom Chao to Phra Ong Chao) * Mom Chao, HSH Princess of Thailand: ''Than Ying'' (daughter of the son of the sovereign and his consort, or great-granddaughter of the sovereign) However, Chao Fa Chulabhorn Walailak received permission from the king to keep her title when she married commoner Virayudh Tishyasarin.

Royal peerage

In addition to royal ranks and titles, royals may also receive noble titles in the style of the nobility. These are referred to as ''krom'' () titles. While the granting of noble titles ceased with the abolition of absolute monarchy in 1932, on very rare occasions the king may still grant an honorary noble title to a royal. The noble title, which consists of a rank and a title, is appended to the royal name and title, prefixed with the word ''krom'' (pronounced ''kromma'' when forming part of the title). For example, the full title of the King's sister is "Somdej Phra Chao Pheenang Ther Chao Fa Galyani Vadhana ''Kromma Luang Narathivat Rajanakarin''. Nevertheless, it is the princely title which will be more frequently omitted when contracting the title ''e.g.'' Somdej Phra Chao Boromawong Ther ''Kromma Phraya Damrong Rajanubhab'' (born
