This research aimed to investigate the frequency of the use of first personal pronouns in Thai political language, and to analyze the semantic components of the usage of first personal pronouns by politicians. The data were collected from speeches, media programs, interviews, official statements, policy statements and the declaration of the dissolution of parliament. The results indicated that Thai politicians typically use seven first personal pronouns: phǒm ‘I (male singular excluding listeners)’ krɑ̀phǒm ‘I (male singular excluding listeners showing formality)’ phûɑk phǒm ‘we (plural excluding listeners)’ dìchɑ̌ n ‘I (female singular excluding listeners)’ rɑw1 ‘we (plural including listeners)’ rɑw2 ‘we (female excluding listeners showing informality)’ and phûɑk rɑw ‘we (plural including listeners)’. The meanings of these first personal pronouns depend on factors including gender, number, including listeners, and the level of formality. Moreover, the results also found that phǒm ‘I (male singular excluding listeners)’ and rɑw1 ‘we (plural including listeners)’ are the highest frequency pronouns used by politicians. The data concerning the frequency of use and the meaning of first personal pronouns were subjected to a componential analysis. The research found that personal pronouns reflect significant social roles, and that political language is the language of solidarity.
