Thai royal and noble titles
（重定向自Phraya）
Thai royal and noble titles are the royal and noble styles indicating relationship to the king which were introduced by King Trailokanat (reigned 1448–1488). The system is rooted in the Thai language equivalent of feudalism, Sakdina (ศักดินา: "power over fields"). It is somewhat similar to peerage, but more complicated and obscure even to most Thais. A title of honor may not be confined to the beginning or the end of the name, but may be split across the name. Those with titles ceased to be known by personal names, and were referred to by the awarded (or similar) title. The King may bestow any title on anyone, although such promotion is personal and the person's children will not normally benefit from it.
