Thai script instance of abugida
Alphabet listing
Thai (along with its sister system, Lao) lacks conjunct consonants and independent vowels, while both designs are common among Brahmic scripts (e.g., Burmese and Balinese). In scripts with conjunct consonants, each consonant has two forms: base and conjoined. Consonant clusters are represented with the two styles of consonants. The two styles may form typographical ligatures, as in Devanagari. Independent vowels are used when a syllable starts with a vowel sign.Sanskrit and Pali
The Thai script (like all Indic scripts) uses a number of modifications to write Sanskrit and related languages (in particular, Pali). Pali is very closely related to Sanskrit and is the liturgical language of Thai Buddhism. In Thailand, Pali is written and studied using a slightly modified Thai script. The main difference is that each consonant is followed by an implied short a (อะ), not the 'o', or 'ə' of Thai: this short a is never omitted in pronunciation, and if the vowel is not to be pronounced, then a specific symbol must be used, the pinthu อฺ (a solid dot under the consonant). This means that sara a (อะ) is never used when writing Pali, because it is always implied. For example, namo is written นะโม in Thai, but in Pali it is written as นโม, because the อะ is redundant. The Sanskrit word 'mantra' is written มนตร์ in Thai (and therefore pronounced mon), but is written มนฺตฺร in Sanskrit (and therefore pronounced mantra). When writing Pali, only 33 consonants and 12 vowels are used.
This is an example of a Pali text written using the Thai Sanskrit orthography: อรหํ สมฺมาสมฺพุทฺโธ ภควา [arahaṃ sammāsambuddho bhagavā]. Written in modern Thai orthography, this becomes อะระหัง สัมมาสัมพุทโธ ภะคะวา arahang sammasamphuttho phakhawa.
In Thailand, Sanskrit is read out using the Thai values for all the consonants (so ค is read as kha and not [ga]), which makes Thai spoken Sanskrit incomprehensible to sanskritists not trained in Thailand. The Sanskrit values are used in transliteration (without the diacritics), but these values are never actually used when Sanskrit is read out loud in Thailand. The vowels used in Thai are identical to Sanskrit, with the exception of ฤ, ฤๅ, ฦ, and ฦๅ, which are read using their Thai values, not their Sanskrit values. Sanskrit and Pali are not tonal languages, but in Thailand, the Thai tones are used when reading these languages out loud.
In the tables in this section, the Thai value (transliterated according to the Royal Thai system) of each letter is listed first, followed by the IAST value of each letter in square brackets. Remember that in Thailand, the IAST values are never used in pronunciation, but only sometimes in transcriptions (with the diacritics omitted). This disjoint between transcription and spoken value explains the romanisation for Sanskrit names in Thailand that many foreigners find confusing. For example, สุวรรณภูมิ is romanised as Suvarnabhumi, but pronounced su-wan-na-phum. ศรีนครินทร์ is romanised as Srinagarindra but pronounced si-nakha-rin.
