 script, where certain 'implied' vowels are unwritten, recent spelling reforms make this definition somewhat problematic. Vowels can be written above, below, in front of, or behind consonants, with some vowel combinations written before, over and after. Spaces and punctuations were traditionally not used, but a space would function in place of a comma or period. Since the letters have no majuscule or minuscule differentiations, rules regarding capitalisation are moot.

History

The Lao script was slowly standardised in the Mekong River valley after the various Tai principalities of the region were merged under the rule of the Kingdom of Lane Xang in the 14th century. This script, known as Tai Noy, has changed little since its inception and continued in use in the Lao-speaking regions of modern-day Laos and Isan, while the Thai alphabet continued to evolve, but similarity of the scripts can still be seen. This script was ultimately influenced by earlier writing systems in use by the Mon and the Khmer.

Traditionally, only secular literature was written with the Lao alphabet. Religious literature was often written in Tai Tham

Consonants

The 27 consonants of the Lao alphabet are divided into three tone classes—high (ສູງ [sǔːŋ]), middle (ກາງ [kaːŋ]), low (ຕ່ຳ tām)—which determine the tonal pronunciation of the word in conjunction with the four tone marks and distinctions between short and long vowels, but aside from tone, there are 21 distinct consonant sounds that occur in the Lao language. Each letter has an acrophonical

 name that either begins with or features the word prominently and is used to teach the letter and serves to distinguish them from other, homophonous consonants. The letter ອ is a special null consonant used as an anchor for vowels, which cannot stand alone, as well as serves as a vowel in its own right.

Note that the Unicode names for the characters ຝ (FO TAM) and ຟ (FO SUNG) are reversed. The same is true for ຣ (LO LING) and ລ (LO LOOT). This error was introduced into the Unicode standard and cannot be fixed, as character names are immutable.

Consonantal Digraphs and Ligatures

Lao also uses digraphs based on combinations of silent ຫ ຫ່ານ with certain other consonants, some of which also have special ligature forms that are optionally used. Because of the first silent component is of the 'high' tone class, all the digraphs and ligatures are also of the high tone class. The older versions of the script also included special forms for combinations of ພ (pʰ) + ຍ (ɲ), ສ (s) + ນ (n), and ມ (m) + ລ (l). In addition, consonant clusters that had the second component of ຣ (r) or ລ (l) were written with a special form ຼ underneath the consonant. Since these were not pronounced in Lao, they were removed during various spelling reforms and this symbol only appears in the ligature ຫຼ.

Vowels

There are only a handful of basic symbols, but they can be combined with other vowel forms and semi-vowels like to create the full repertoire of diphthongs and triphthongs used in the language. Vowels cannot stand alone or begin a syllable, so the null consonant, ອ, which can function as a vowel in its own right, is used as a base. The names of the vowels are just as easy as saying sala (ສຣະ, sáʔrāʔ) before the vowel sign. Some vowels have unique names, and these are ໃອ (ໄມ້ມ້ວນ, mâj muân, rolled stem), ໄອ (ໄມ້ມາຽ, mâj máːj, unwound stem), ອົ (ໄມ້ກົງ, mâj kòŋ, straight stem), ອັ (ໄມ້ກັນ, mâj kàn, ear stem), ອຽ (ວິຣາມ, vī ráːm), and ອໍ (ນິກຄະຫິດ, nīk kʰā hǐt).
