At the same time, a clerical vocabulary emerged, much smaller but similar in function and origin to the royal vocabulary. The clerical vocabulary, also composed mainly of borrowings from Khmer, enabled the common people to communicate with and about monks. Lexical items from standard Thai, royal vocabulary, and clerical vocabulary are shown side by side in the table below: Personal pronouns are the most numerous and complex of pronominal forms in Thai. Personal pronouns may make the following semantic distinctions:  Kinship terms are used pronominally to elevate or demonstrate solidarity with an addressee. To address a listener as kin is, in effect, to confer the listener with the same status as the aforementioned kin. Generally, kinship terms contain both literal and displaced meanings. Kinship terms are considered literal in cases of blood kin, affinal kin, and teknonymy. They are considered displaced when used with kinlike individuals: intimate friends of kin or kin of intimate friends. When using kinship terms, age is critical. Speakers must estimate the age of an addressee to determine his or her generation and choose an appropriate kinship term. Kinship terms commonly used as honorific pronominals are summarized in the table below. Speakers may demonstrate additional respect by adding the polite title "khun" before any kinship term. Kinship terms are commonly followed by personal names or nicknames. Status terms denote referents in terms of occupation or status. While some status terms are used as first, second, or third person pronouns, others are restricted to second and third person only. Many pronominal status terms are preceded by titles, such as "khun" or "thân". Status terms may also be used as titles before given names. A few status terms frequently used as pronominals are presented in the table below: In Thai, a person's full name consists of a given name followed by a surname or family name. In addition, most individuals have a nickname. As pronominals, given names are used most frequently in second person form. Given names are often preceded by the courtesy title "khun" when addressing friends or acquaintances. Given names are sometimes truncated to convey mild informality. Nicknames, like given names, are used most often in second person. They generally do not take titles. Nicknames are a friendly, affectionate way to show intimacy between interlocuters. Honorific particles are added to the end of an utterance or clause to show respect to the addressee.
