Taiwanese dating etiquette
Note that the latter-day Royal Thai General System of Transcription would transcribe it as "Wetchachiwa".
Formal personal names follow from traditional practice to include individual awards of palace-given names.
East Asian monarchs often adopted Regnal names upon ascending the throne, as was done in Thailand until the present day.
In addition, subjects of a monarch may be awarded both a title and a name, such as in the case of Sing (or Singh) Singhaseni (.) Kings Rama I and Rama II were both awarded noble titles and names before they assumed regnal names, which were then changed by subsequent kings.
As a measure of the diversity of Thai names, in a sample of 45,665 names, 81% of family names were unique, and 35% of given names were unique: the people with shared family names are thus related, and the diversity of given names is conventional.
The evolution of Thai nicknames dates back to the Sukhothai era, when names were used to mark the order of children.
Nicknames such as "Ai", "Yee", and "Sam" designated children as "one", "two", and "three".
For instance, Hugo Chakrabongse is a descendant of Prince Chakrabongse Bhuvanath.
Some (far removed) descendants of royalty add the preposition and nobility particle "na" (ณ) to geographical names to create surnames, in the same way that members of German noble families use von.
