Tai Lue language

The initials t͡s- and s- are palatalized before front vowels (which in the language are i, e, and ɛ) and become t͡ɕ- and ɕ-, respectively. For example, /t͡síŋ/ "hard" and /si᷄p/ "ten" are pronounced as [t͡ɕiŋ˥] and [ɕip˧˥] respectively. (Some textbooks denote t͡s as c).

Generally, vowels in open syllables (without codas) occur as long whereas ones in closed syllables are short (except /aː/ and /uː/).

The table below presents six phonemic tones in unchecked syllables, i.e. closed syllables ending in sonorant sounds such as [m], [n], [ŋ], [w], and [j] and open syllables. There are six tones for unchecked syllables, although only three are allowed in checked syllables (those ending with -p, -t or -k).

The table below presents two phonemic tones in checked syllables, i.e. closed syllables ending in a glottal stop [ʔ] and obstruent sounds which are [p], [t], and [k].

Word order is usually subject–verb–object (SVO); modifiers (e.g. adjectives) follow nouns.

Many words differ from Thai greatly:

• ยี่สิบ → ᨪᩣ᩠ᩅ (/jîː sìp/ → /sâːw/, twenty; cf. Lao: /sáːw/, Northern Thai: /sāw/)
• พูด → ᩋᩪᩢ (/pʰûːt/ → /ʔu᷅ː/, to speak; cf. Northern Thai: /ʔu᷇ː/)
• พี่ชาย → ᩋᩢᩣ᩠ᨿ (/pʰîː t͡ɕʰaːj/ → /ʔa᷅ːj/, older brother; cf. Lao: /ʔâːj/, Northern Thai: /ʔa᷇ːj/)

Some words differ in tone only:

• หนึ่ง → ᨶ᩠ᨦᩧ᩵ (/nɯŋ/, one)
• หก → ᩉᩫ᩠ᨠ (/hók/, six)
• เจ็ด → ᩮᨧ᩠ᨯ (/t͡ɕét/, seven)
• สิบ → ᩈᩥ᩠ᨷ (/síp/, ten)
• กิน → ᨠᩥ᩠ᨶ (/kín/, to eat)

Some words differ in a single sound and associated tone. In many words, the initial ร (/r/) in Thai is ฮ (/h/) in Tai Lue, as is also the case in Lao and Tai Yuan:

• ร้อน → ᩁᩢᩬᩁ (/rɔ́n/ → /hɔ̀n/, hot; cf. Lao: /hɔ̂n/, Northern Thai: /hɔ́ːn/)
• รัก → ᩁᩢ᩠ᨠ (/rák/ → /hak/, to love; cf. Lao: /hāk/, Northern Thai: /ha᷇k/)
• รู้ → ᩁᩪᩢ (/rúː/ → /hùː/, to know; cf. Lao: /hûː/, Northern Thai: /húː/)

Aspirated consonants in the low-class consonant group(อักษรต่ำ /ʔàk sɔ̌n tàm/) become unaspirated:

• เชียงราย → ᨩ᩠ᨿᨦᩁᩣ᩠ᨿ (/t͡ɕʰiaŋ raːj/ → /t͡ɕêŋ hâːj/, Chiang Rai city and province)
• คิด → ᨣᩧ᩠ᨯ (/kʰít/ → /kɯt/, to think; cf. Northern Thai: /kɯ́t/)
• พ่อ → ᨻᩳ᩵ (/pʰɔ̂/ → /pɔ/, father; cf. Northern Thai: /pɔ̂ː/)
• ทาง → ᨴᩤ᩠ᨦ (/tʰaːŋ/ → /tâːŋ/, way; cf. Northern Thai: /tāːŋ/)

(Note that the vowels also differ greatly between Tai Lue and Thai in many words, even though they are etymologically related and share the same root.)

Though many aspirated consonants often become unaspirated, when an unaspirated consonant is followed by ร (/r/) the unaspirated consonant becomes aspirated:

• ประเทศ → ᨷᩕᨴᩮ᩠ᩆ (/praʔtʰêːt/ → /pʰaʔtêːt/, country; cf. Northern Thai /pʰa.têːt/)

Other differences:

• ให้ → ᩉᩨᩢ (/hâj/ → /hɯ᷅/, to give, let)

An ancient script, also used in Kengtung, Northern Thailand and Northern Laos centuries ago.

The Tham script is called 老傣文 lao dai wen (Old Dai script) in Chinese. Readable by the most people in Burma, Laos, Thailand and Vietnam.

New Tai Lue is a modernization of the Lanna alphabet (also known as the Tai Tham script), which is similar to the Thai alphabet, and consists of 42 initial consonant signs (21 high-tone class, 21 low-tone class), seven final consonant signs, 16 vowel signs, two tone letters and one vowel shortening letter (or syllable-final glottal stop). Vowels signs can be placed before or after the syllable initial consonant.

Similar to the Thai alphabet, the pronunciation of the tone of a syllable depends on the class the initial consonant belongs to, syllable structure and vowel length, and the tone mark.
