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
Phra Ong Chao Disuankumaan). There are 5 feudal titles for prince/princess: The ranks of royal peerage are: •
