The official language of Thailand is Thai. This language belongs to the Tai-Kadai language family and is primarily spoken by the majority of the population. Thai is known for its unique script, which is an abugida based on Brahmic script, and for its tonal nature, which means that the tone in which a word is spoken can change its meaning. Besides being the official language, Thai is a important part of the nation’s cultural identity and is used in government, media, and education throughout the country.
