Thai is the official language of Thailand and serves as a vital tool for national connection.

As of 2024, more than 70 million people speak the language. It is the most widely spoken of the 60 languages found within the country. Standard Thai is used for education, government, news reporting, and all forms of media. Because of this, many people in the northern, southern, and northeastern regions are bilingual. They often speak regional dialects at home while using Central Thai in public life.

Linguistically, Thai is classified as a tonal and analytic language. Being tonal means that the pitch of a speaker's voice changes a word's meaning.

An analytic language uses small words or relational markers to show how parts of a sentence work together. The language also features a complex orthography, which is a specialized writing system. This system uses the Thai script to represent sounds and tones. This relationship between spelling and sound is intricate due to centuries of linguistic evolution.

Thai belongs to the Kra–Dai language family.

Specifically, it is part of the Southwestern branch of Tai languages. This large language family includes many indigenous languages spoken in an arc from Hainan and Guangxi. These languages stretch south through Laos and Northern Vietnam toward the Cambodian border. While many linguists classify related varieties like Northern or Southern Thai as distinct languages, many native speakers view them as regional dialects. They often describe these variations as simply "different kinds of Thai."

The history of the language reveals a deep connection to neighboring cultures. During the Ayutthaya period, which lasted from 1351 to 1767 A.D., the capital was a bilingual society.

People spoke both Thai and Khmer. After several military victories in 1369, 1388, and 1431, the number of Khmer-speaking captives increased. This strengthened the use of both languages for a long time. Eventually, a language shift occurred where Khmer fell out of common use. However, the shift left a permanent mark on the Thai language.

This historical shift resulted in a massive transfer of vocabulary and grammar. Many Khmer elements permeated all aspects of Thai. In the late Ayutthaya period, the language became a thorough mixture of Thai and Khmer. In some cases, there were more Khmer words in use than original Tai words. Thais even used Khmer grammatical rules to create new multi-syllable words and phrases. They also borrowed Khmer expressions and proverbs, adapting them into Thai. This influence extended to the royal vocabulary used in formal settings.

In addition to Khmer, Thai vocabulary is heavily influenced by religious and classical sources. More than half of the Thai vocabulary is derived from or borrowed from Pali and Sanskrit. These languages are closely linked to Theravada Buddhism. The language also incorporates elements from Mon and Old Khmer. When studying the royal vocabulary, known as Rajasap, researchers find that three languages work together: Thai, Khmer, and Khmero-Indic. This shows how different cultural and religious influences merged to expand the Thai lexicon.

Between 1300 and 1600 C.E., the sounds of Thai underwent a major transformation.

During this time, the distinction between voiced and voiceless consonants was lost. For example, plain voiced stops became voiceless aspirated stops. This change caused a significant "tone split." Every original tone in Old Thai split into two new tones. A lower-pitched tone developed from syllables that began with voiced consonants. A higher-pitched tone developed from those beginning with voiceless consonants. This process explains why modern Thai has a complex system of consonant classes and tone marks.
