Kam Mueang (تايلندية الشمالية: ᨣᩴᩤᨾᩮᩬᩥᨦ, กำเมือง ( استمع)) or Northern Thai language (بالتايلندية: ภาษาไทยถิ่นเหนือ) is the language of the Northern Thai people of Lanna, Thailand. It is a Southwestern Tai language that is closely related to Tai Lue language. Kam Mueang has approximately six million speakers, most of whom live in the native Northern Thailand, with a smaller community of Lanna speakers in northwestern Laos.

Speakers of this language generally consider the name "Tai Yuan" to be pejorative. They refer to themselves as Khon Mueang (ᨤᩫ᩠ᨶᨾᩮᩬᩥᨦ, คนเมือง, nod – literally "people of Mueang" meaning "city dwellers"), Lanna, or Northern Thai. The language is also sometimes referred to as Phayap (พายัพ, النطق التايلندي: [pʰāː.jáp]), "Northwestern (speech)".

The term Yuan is still sometimes used for Northern Thai's distinctive Tai Tham alphabet, which is closely related to the old Tai Lue alphabet and the Lao religious alphabets. The use of the Tua Mueang, as the traditional alphabet is known, is now largely limited to Buddhist temples, where many old sermon manuscripts are still in active use. There is no active production of literature in the traditional alphabet, and when used in writing standard Thai script is invariably used. The modern spoken form is called Kam Mueang. There is a resurgence of interest in writing it in the traditional way, but the modern pronunciation differs from that prescribed in spelling rules.

 Classification

للمزيد من المعلومات: Tai–Kadai languages, Tai languages, and Tai peoples

Northern Thai is classified as one of the Chiang Saen languages—others being Thai, Southern Thai and numerous smaller languages, which together with the Northwestern Tai and Lao-Phutai languages, form the Southwestern branch of Tai languages. The Tai languages are a branch of the Kra–Dai language family, which encompasses a large number of indigenous languages spoken in an arc from Hainan and Guangxi south through Laos and Northern Vietnam to the Cambodian border.

From a purely genealogical standpoint, most linguists consider Northern Thai to be more closely related to Central Thai than to Lao or Isan, but the language has been heavily influenced by both Lao and Central Thai throughout history. All Southwestern Tai languages form a coherent dialect continuum of more or less mutually intelligible varieties, with few sharp dividing lines. Nevertheless, Northern Thai has today become closer to the Central Thai language, as Standard Thai is the principal language of education and government and spoken throughout Thailand.

 التاريخ

للمزيد من المعلومات: Tai languages and Tai peoples

 هجرة التاي

Map showing the general migration patterns and diversification of the Tai peoples and languages from the original Tai Urheimat of southeastern China.

The ancestors of the Northern Thai people were speakers of Southwestern Tai dialects that migrated from what is now southeastern China, specifically what is now Guangxi and northern Vietnam where the diversity of various Tai languages suggests an Urheimat. The Southwestern Tai languages began to diverge from the Northern and Central branches of the Tai languages, covered mainly by various Zhuang languages, sometime around 112 AD, but likely completed by the sixth century. Due to the influx of Han Chinese soldiers and settlers, the end of the Chinese occupation of Vietnam, the fall of Jiaozhi and turbulence associated with the decline and fall of the Tang dynasty led some of the Tai peoples speaking Southwestern Tai to flee into Southeast Asia, with the small-scale migration mainly taking place between the eighth and twelfth centuries. The Tais split and followed the major river courses, with the ancestral Northern Thai originating in the Tai migrants that followed the Mekong River.

 الممالك المهندة

Ancestors of the Northern Thai people established Ngoenyang, an early kingdom that existed between the 7th to 13th centuries, as well as smaller kingdoms like Phayao, in what is now modern-day northern Thailand. They settled in areas adjacent to the kingdom of Hariphunchai, coming into contact with Mon-speaking people whose writing system was eventually adapted for the Northern Thai language as the Tai Tham script. In the 13th century, King Mangrai consolidated control of these territories, establishing the kingdom of Lan Na. In the 15th century, King Tilokkarat ushered in a golden age for Northern Thai literature, with a profusion of palm leaf manuscripts written in Tai Tham, using vernacular Northern Thai and interspersed with Pali and Buddhist Indic vocabulary.

 Thai subordination

In 1775, Kawila of Lampang revolted with Siamese assistance, and captured the city, ending 200 years of Burmese rule. Kawila was installed as the prince of Lampang and Phraya Chaban as the prince of Chiang Mai, both as vassals of Siam. In 1899, Siam annexed the Northern Thai principalities, effectively dissolving their status as sovereign tributary states.

The Compulsory Education Act of 1921 banned schools and temples from using languages other than Central Thai (standard Thai), in an effort to bring remote regions under Siamese control. Northern Thai was relegated from the public sphere, with influential religious leaders like Khruba Srivichai jailed for using Northern Thai in sermons. In the 1940s, authorities promulgated Thai cultural mandates that reinforced the importance of learning and using Central Thai as the prestige language.

These economic and educational pressures have increased the use of standard Thai to the detriment of other regional languages like Northern Thai. Today, Northern Thai is typically code-switched with standard Thai, especially in more developed and urbanized areas of Northern Thailand, whereas exclusive use of Northern Thai remains prevalent in more remote areas.

 Dialects

Thanajirawat (2018) classifies Tai Yuan into five major dialect groups based on tonal split and merger patterns. (See also Proto-Tai language#Tones)

1. most Tai Yuan varieties in Thailand, Laos and Myanmar
2. Bokeo Province, Laos (A12-34 and BCD123-4 (B4=DL4=DS4))
3. Mae Chaem District, Chiang Mai Province and Laplae District, Uttaradit Province, Thailand (A12-34 and BCD123-4 (A34=B123=DL123))
4. Tha Pla District, Uttaradit Province and Xayaburi Province, Laos (A12-34, BDL1234, and CDS123-4)
5. Ratchaburi Province, Thailand (A12-34 and BCD123-4 (A34=B123=DL123, B4=C4=DL4))

 Vowels

The basic vowels of the Northern Thai language are similar to those of Standard Thai. They, from front to back and close to open, are given in the following table. The top entry in every cell is the symbol from the International Phonetic Alphabet, the second entry gives the spelling in the Thai alphabet, where a dash (–) indicates the position of the initial consonant after which the vowel is pronounced. A second dash indicates that a final consonant must follow.

	Front		Central		Back
	short	long	short	long	short	long
Close	/i/  -ิ	/iː/  -ี	/ɯ/  -ึ	/ɯː/  -ื-	/u/  -ุ	/uː/  -ู
Mid	/e/ เ-ะ	/eː/ เ-	/ɤ/ เ-อะ	/ɤː/ เ-อ	/o/ โ-ะ	/oː/ โ-
Open	/ɛ/ แ-ะ	/ɛː/ แ-	/a/ -ะ, -ั-	/aː/ -า	/ɔ/ เ-าะ	/ɔː/ -อ

The vowels each exist in long-short pairs: these are distinct phonemes forming unrelated words in Northern Thai, but usually transliterated the same: เขา (khao) means "they/them", while ขาว (khao) means "white".

The long-short pairs are as follows:

 Tones

The six phonemic tones in Northern Thai pronounced with the syllable '/law/':

There are six phonemic tones in the Chiang Mai dialect of Northern Thai: low-rising, low-falling, high-level with glottal closure, mid-level, high-falling, and high-rising. or low-rising, mid-low, high-falling, mid-high, falling, and high rising-falling

 Contrastive tones in smooth syllables

The table below presents six phonemic tones in the Chiang Mai and Nan dialects in smooth syllables, i.e. closed syllables ending in sonorant sounds such as [m], [n], [ŋ], [w], and [j] and open syllables. Sources have not agreed on the phonetic realization of the six tones in the Chiang Mai dialect. The table presents information based on two sources, one from Gedney (1999) and the other one from the Lanna dictionary (2007) which is a Northern Thai-Thai dictionary. Although published in 1999, Gedney's information about the Chiang Mai dialect is based on data he collected from one speaker in Chiang Mai in 1964 (p. 725). As tones may change within one's lifetime (e.g., Bangkok Thai tones have changed over the past 100 years), the information about the six tones from Gedney (1999) should be considered with caution.

 Grammar

The grammar of Northern Thai is similar to those of other Tai languages. The word order is subject–verb–object, although the subject is often omitted. Just as Standard Thai, Northern Thai pronouns are selected according to the gender and relative status of speaker and audience.

 Adjectives and adverbs

There is no morphological distinction between adverbs and adjectives. Many words can be used in either function. They succeed the word which they modify, which may be a noun, verb, or another adjective or adverb.

• ᨾᩯ᩵ᨿᩥ᩠ᨦᨳᩮᩢ᩶ᩣ / แม่ญิงเฒ่า (mae nying thao, [mɛ̂ː.ɲīŋ.tʰa᷇w]) an old woman
• ᨾᩯ᩵ᨿᩥ᩠ᨦᨴᩦ᩵ᨳᩮᩢ᩶ᩣᩅᩮᩥ᩠ᨿ / แม่ญิงตี้เฒ่าโวย (mae nying ti thao woi, [mɛ̂ː.ɲīŋ.tîː.tʰa᷇w.wōːj]) a woman who became old quickly

Because adjectives can be used as complete predicates, many words used to indicate tense in verbs (see Verbs:Aspect below) may be used to describe adjectives.

• ᨡ᩶ᩣᩉᩥ᩠ᩅ / ข้าหิว (kha hiw, [kʰa᷇ː hǐw]) I am hungry.
• ᨡ᩶ᩣᨧᩢᩉᩥ᩠ᩅ / ข้าจะหิว (kha cha hiw, [kʰa᷇ː t͡ɕa.hǐw]) I will be hungry.
• ᨡ᩶ᩣᨠ᩵ᩣᩴᩃᩢ᩠ᨦᩉᩥ᩠ᩅ / ข้ากะลังหิว (kha kalang hiw, [kʰa᷇ː ka.lāŋ hǐw]) I am hungry right now.
• ᨡ᩶ᩣᩉᩥ᩠ᩅᩓ᩠ᩅ / ข้าหิวแล้ว (kha hiu laew, [kʰa᷇ː hǐw lɛ́ːw]) I am already hungry.

 Verbs

Verbs do not inflect. They do not change with person, tense, voice, mood, or number; nor are there any participles.

• ᨡ᩶ᩣᨲᩦᨻᩮᩥ᩠᩵ᨶ / ข้าตี๋เปิ้น (kha ti poen, [kʰa᷇ː tǐː pɤ̂n]), I hit him.
• ᨻᩮᩥ᩠᩵ᨶᨲᩦᨡ᩶ᩣ / เปิ้นตี๋ข้า (poen ti kha, [pɤ̂n tǐː kʰa᷇ː]), He hit me.

The passive voice is indicated by the insertion of ᨯᩰ᩠ᨶ / โดน (don, [dōːn]) before the verb. For example:

• ᨻᩮᩥ᩠᩵ᨶᨯᩰᩫ᩠ᨶᨲᩦ / เปิ้นโดนตี๋ (poen don ti, [pɤ̂n dōːn tǐː]), He is hit or He got hit. This describes an action that is out of the receiver's control and, thus, conveys suffering.

To convey the opposite sense, a sense of having an opportunity arrive, ᨯᩱ᩶ / ได้ (dai, [da᷇j], can) is used. For example:

• ᨻᩮᩥ᩠᩵ᨶᨧᩢᨯᩱ᩶ᨸᩱᩋᩯ᩠᩵ᩅᨾᩮᩬᩥᨦᩃᩣ᩠ᩅ / เปิ้นจะได้ไปแอ่วเมืองลาว (poen cha dai pai aew mueang lao, [pɤ̂n t͡ɕa.da᷇j pǎj ʔɛ̀w mɯ̄a̯ŋ lāːw]), He gets to visit Laos.
• ᨻᩮᩥ᩠᩵ᨶᨲᩦᨯᩱ᩶ / เปิ้นตี๋ได้ (poen ti dai, [pɤ̂n tǐː da᷇j]), He is/was allowed to hit or He is/was able to hit

Negation is indicated by placing บ่ (bor,[bɔ̀ː] or [bàʔ] not) before the verb.

• ᨻᩮᩥ᩠᩵ᨶᨷᩴ᩵ᨲᩦ / เปิ้นบ่ตี๋, (poen bor ti, [pɤ̂n bɔ̀ː tǐː]) He is not hitting. or He not hit.

Aspect is conveyed by aspect markers before or after the verb.

Present can be indicated by ᨠ᩵ᩣᩴᩃᩢ᩠ᨦ / กะลัง (kalang, [ka.lāŋ], currently) or ᨠ᩵ᩣᩴᩃᩢ᩠ᨦᩉᩡ / กะลังหะ (kalangha, [ka.lāŋ.hà], currently) before the verb for ongoing action (like English -ing form), by ᩀᩪ᩵ / อยู่ (yu, [jùː]) after the verb, or by both. For example:

• ᨻᩮᩥ᩠᩵ᨶᨠ᩵ᩣᩴᩃᩢ᩠ᨦᩉᩡᩃᩫ᩠᩵ᨶ / เปิ้นกะลังหะล่น (poen kalangha lon, [pɤ̂n ka.lāŋ.hà lôn]), or
• ᨻᩮᩥ᩠᩵ᨶᩃᩫ᩠᩵ᨶᩀᩪ᩵ / เปิ้นล่นอยู่ (poen lon yu, [pɤ̂n lôn jùː]), or
• ᨻᩮᩥ᩠᩵ᨶᨠ᩵ᩣᩴᩃᩢ᩠ᨦᩃᩫ᩠᩵ᨶᩀᩪ᩵ / เปิ้นกะลังหะล่นอยู่ (poen kalanɡha lon yu, [pɤ̂n ka.lāŋ.hà lôn jùː]), He is running.

Future can be indicated by ᨧᩢ / จะ (cha, [t͡ɕǎʔ], will) before the verb or by a time expression indicating the future. For example:

• ᨻᩮᩥ᩠᩵ᨶᨧᩢᩃᩫ᩠᩵ᨶ / เปิ้นจะล่น (poen cha lon, [pɤ̂n t͡ɕa.lôn]), He will run or He is going to run.

Past can be indicated by ᨯᩱ᩶ / ได้ (dai, [da᷇j]) before the verb or by a time expression indicating the past. However, ᩓ᩠ᩅ / แล้ว (laew,  :[lɛ́ːw], already) is often used to indicate the past aspect by being placed behind the verb. Or, both ได้ and แล้ว are put together to form the past aspect expression. For example:

• ᨻᩮᩥ᩠᩵ᨶᨯᩱ᩶ᨠᩥ᩠ᨶ / เปิ้นได้กิ๋น (poen dai kin, [pɤ̂n da᷇j kǐn]), He ate.
• ᨻᩮᩥ᩠᩵ᨶᨠᩥ᩠ᨶᩓ᩠ᩅ / เปิ้นกิ๋นแล้ว (poen kin laew, [pɤ̂n kǐn lɛ́ːw], He has eaten.
• ᨻᩮᩥ᩠᩵ᨶᨯᩱ᩶ᨠᩥ᩠ᨶᩓ᩠ᩅ / เปิ้นได้กิ๋นแล้ว (poen dai kin laew, [pɤ̂n da᷇j kǐn lɛ́ːw]), He's already eaten.

Aspect markers are not required.

• ᨡ᩶ᩣᨠᩥ᩠ᨶᨴᩦ᩵ᩉᩢ᩠᩶ᨶ / ข้ากิ๋นตี้หั้น (kha kin tihan, [kʰa᷇ kǐn tîː.ha᷇n]), I eat there.
• ᨡ᩶ᩣᨠᩥ᩠ᨶᨴᩦ᩵ᩉᩢ᩠᩶ᨶᨲᩅᩤ / ข้ากิ๋นตี้หั้นตะวา (kha kin tihan tawa, [kʰa᷇ kǐn tîː.ha᷇n ta.wāː]), I ate there yesterday.
• ᨡ᩶ᩣᨠᩥ᩠ᨶᨴᩦ᩵ᩉᩢ᩠᩶ᨶᩅᩢ᩠ᨶᨻᩕᩪᨠ / ข้ากิ๋นตี้หั้นวันพูก (kha kin tihan wanphuk, [kʰa᷇ kǐn tîː.ha᷇n wān.pʰûːk]), I'll eat there tomorrow.

 Final particles

Northern Thai has a number of final particles, which have different functions.

 Interrogative particles

Some of the most common interrogative particles are kor (ᨣᩴ᩵ / ก่อ, [kɔ̀ː]) and ka (ᨣᩤ / กา, /kāː/)

• kor (ᨣᩴ᩵ / ก่อ, [kɔ̀ː], denoting yes/no question)

• ᨾ᩠ᩅ᩵ᩁᨣᩴ᩵ / ม่วนก่อ (muan kor, [mûa̯n kɔ̀ː]) Is it fun?

• ᨾ᩠ᩅ᩵ᩁᨣᩤ / ม่วนกา (muan ka, [mûa̯n kāː]) It is fun, right?

 Imperative particles

Some imperative particles are ᩃᩯ᩵ (แล่), ᨧᩥ᩠᩵ᨾ (จิ่ม), and ᨴᩮᩬᩥᩡ (เตอะ).

lae (ᩃᩯ᩵ / แล่, [lɛ̂ː])

• ᨠᩥ᩠ᨶᨴᩮᩬᩥᩡ / กิ๋นเต๊อะ (kin toe, /kǐn tɤ᷇ʔ/) Eat, please.

 Polite particles

Polite particles include ᨣᩕᩢ᩠ᨷ (คับ) and ᨧᩮᩢ᩶ᩣ (เจ้า).

 Nouns

Nouns are uninflected and have no gender; there are no articles.

Nouns are neither singular nor plural. Some specific nouns are reduplicated to form collectives: ᩃᩡᩋᩬ᩵ᩁ / ละอ่อน (la-orn, [la.ʔɔ̀ːn], child) is often repeated as ᩃᩡᩋᩬ᩵ᩁᪧ ละอ่อน ๆ (la-orn la-orn, [la.ʔɔ̀ːn la.ʔɔ̀ːn],) to refer to a group of children.

The word ᩉ᩠ᨾᩪ᩵ / หมู่(mu, [mùː]) may be used as a prefix of a noun or pronoun as a collective to pluralize or emphasise the following word. (ᩉ᩠ᨾᩪ᩵ᨹᩫ᩠ᨾ / หมู่ผม, mu phom, [mùː pʰǒm], we (exclusive), masculine; ᩉ᩠ᨾᩪ᩵ᩁᩮᩢᩣ / หมู่เฮา mu hao, [mùː hāw], emphasised we; ᩉ᩠ᨾᩪ᩵ᩉ᩠ᨾᩣ / หมู่หมา mu ma, [mùː mǎː], (the) dogs).

Plurals are expressed by adding classifiers, used as measure words (ลักษณนาม), in the form of noun-number-classifier ( ᨣᩕᩪᩉ᩶ᩣᨤᩫ᩠ᨶ / คูห้าคน, "teacher five person" for "five teachers").

 Pronouns

Pronouns may be omitted once they have already been established in the first sentence, unless the pronoun in the following sentences is different from the first sentence. The pronoun "you" may also be omitted if the speaker is speaking directly to a second person. Moreover, names may replace pronouns, and they can even replace the first person singular pronoun.

 Vocabulary

Northern Thai shares much vocabulary with Standard Thai, especially scientific terms, which draw many prefixes and suffixes from Sanskrit and Pali, and it also has its own distinctive words. Just like Thai and Lao, Northern Thai has borrowed many loanwords from Khmer, Sanskrit, and Pali.

 Writing system

Northern Thai in its own alphabet, the Tai Tham alphabet

Currently, different scripts are used to write Northern Thai. Northern Thai is traditionally written with the Tai Tham script, which in Northern Thai is called tua mueang (ᨲᩫ᩠ᩅᨾᩮᩬᩥᨦ ตั๋วเมือง /tǔa.mɯ̄aŋ/) or tua tham (ᨲᩫ᩠ᩅᨵᩢᨾ᩠ᨾ᩺ ตั๋วธัมม์ /tǔa.tʰām/). However, native speakers are presently illiterate in the traditional script; therefore, they instead use the Thai script to write the language. In Laos, the Lao script is commonly used to write Northern Thai.

A sign written in Northern Thai, Thai, and English

Some problems arise when the Thai script is used to write Northern Thai. In particular, Standard Thai script cannot transcribe all Northern Thai tones. The two falling tones in Northern Thai correspond to a single falling tone in Thai. Specifically, Northern Thai has two types of falling tones: high-mid falling tone (˥˧) and high-falling tone (˥˩). However, Thai lacks the distinction between the two falling tones, not having a high-falling tone (˥˧). When using Thai script to write Northern Thai tones, the distinction of the two falling tones is lost because Thai script can only indicate a low falling tone (˥˩). As an example, the tonal distinction between /ka᷇ː/ (ก้า (ᨠᩖ᩶ᩣ กล้า) "to be brave") and /kâː/ (ก้า (ᨣ᩵ᩤ ค่า) "value") is lost when written in Thai since as only /kâː/ (ก้า) is permitted. Consequently, the meaning of ก้า is ambiguous as it can mean both "to be brave" and "value". Similarly, /pa᷇ːj/ (ป้าย (ᨸ᩶ᩣ᩠ᨿ ป้าย) "sign") and /pâːj/ (ป้าย (ᨻ᩵ᩣ᩠ᨿ พ่าย) "to lose") have the same problem and only /pâːj/ (ป้าย) is permitted. As a result, the spelling ป้าย is ambiguous because it can mean both "sign" or "to lose". Such tonal mergence ambiguity is avoided when the language is written with the Northern Thai script.

 Northern Thai and Standard Thai

The tables below present the differences between Northern Thai and Standard Thai.

 Different sounds

Unlike Northern Thai, Standard Thai lacks alveolo-palatal nasal sound (/ɲ/). Thus, the alveolo-palatal nasal sound (/ɲ/) and the palatal approximant sound (/j/) in Northern Thai both correspond to the palatal approximant sound in Standard Thai:

There is not a straightforward correspondence between the tones of Northern and Standard Thai. It also depends on the initial consonant, as can be seen from the merged Gedney tone boxes for Standard Thai and the accent of Chiang Mai:

Note that the commonalities between columns are features of the Chiang Mai accent. On the other hand, the relationships between rows are typical of Northern Thai, being found for at least for Chiang Mai, Chiang Rai, Phayao, Nan and Prae, and extending at least to Tak and the old 6-tone accent of Tai Khuen, except that the checked syllables of Chiang Rai are more complicated.

The primary function of a tone box is etymological. However, it also serves as a summary of the rules for tone indication when the writing system is essentially etymological in that regard, as is the case with the major Tai-language writing systems using the Thai, Lanna, New Tai Lue, Lao and Tai Dam scripts.

Some words differ only as a result of the regular tone correspondences:

Standard Thai	Northern Thai	gloss
[hòk] หก	[hǒk] ᩉᩫ᩠ᨠ ห๋ก	six
[t͡ɕèt] เจ็ด	[t͡ɕět] ᨧᩮᩢ᩠ᨯ เจ๋ด	seven
[sìp] สิบ	[sǐp] ᩈᩥ᩠ᨷ สิ๋บ	ten
[pēn] เป็น	[pěn] ᨸᩮ᩠ᨶ เป๋น	be (copula)
[kīn] กิน	[kǐn] ᨠᩥ᩠ᨶ กิ๋น	eat

Other tone differences are unpredictable, such as:

Standard Thai	Northern Thai	gloss
[nɯ̀ŋ] หนึ่ง	[nɯ̂ŋ] ᨶᩧ᩠᩵ᨦ นึ่ง	one

Some words differ in a single sound and associated tone. In many words, the initial ร (/r/) in Standard Thai corresponds to ฮ (/h/) in Northern Thai:

Standard Thai	Northern Thai	gloss	note
[rɔ́ːn] ร้อน	[hɔ́ːn] ᩁᩬ᩶ᩁ ฮ้อน	hot	cf. Lao: ຮ້ອນ [hɔ̂ːn] "to be hot" and Shan: ႁွၼ်ႉ [hɔ̰n] "to be hot"
[rák] รัก	[ha᷇k] ᩁᩢ᩠ᨠ ฮัก	love	cf. Lao: ຮັກ [hāk] "to love" and Shan: ႁၵ်ႉ [ha̰k] "to love"
[rúː] รู้	[húː] ᩁᩪ᩶ ฮู้	know	cf. Lao: ຮູ້ [hûː] "know" and Shan: ႁူ [hṵ] "know"

 Aspiration of initial consonants

Some aspirated consonants in the low-class consonant group (อักษรต่ำ /ʔàk.sɔ̌ːn.tàm/) in Standard Thai correspond to unaspirated sounds in Northern Thai. These sounds include ค, ช, ท, and พ (/kʰ/, /tɕʰ/, /tʰ/, and /pʰ/ respectively), but sounds such as ฅ, คร, ฆ, ฒ, พร, ภ (/kʰ/, /kʰr/, /kʰ/, /tʰ/, /pʰr/, and /pʰ/ respectively) remain aspirated. Such aspirated consonants that are unaspirated in Northern Thai correspond to unaspirated voiced sounds in Proto-Tai which are *ɡ, *ɟ, *d, and *b (ค, ช, ท, and พ respectively).:

[tʰām] ธรรม	[tʰām] ᨵᨾ᩠ᨾ᩺ ธัมม์	Dharma	cf. Tai Lü: ᦒᧄ [tʰâm] "Dharma"

Though a number of aspirated consonants in Standard Thai often correspond to unaspirated sounds in Northern Thai, when an unaspirated consonant is followed by ร (/r/) the unaspirated consonant becomes aspirated:
