Khmer script

language culture Maturity 11-13 Next article →

The Khmer script is an abugida, also known as an alphasyllabary, used to write the Khmer language. This is the official language of Cambodia.

Beyond everyday use, the script is also employed to write Pali, which is used in the Buddhist liturgy of Cambodia and Thailand. Writing in Khmer follows a left-to-right direction. A unique feature of the script is that words within a single sentence or phrase are generally run together. There are usually no spaces between words. This creates a continuous flow of characters across the page.

To understand how the script works, one must look at the relationship between consonants and vowels. Each consonant character carries an inherent vowel sound. These inherent sounds are either â or ô. In the Khmer language, these are categorized into the a-series and the o-series. Most vowel sounds are represented as dependent vowels. These are additional marks, or diacritics, that accompany a consonant. They indicate which vowel sound should follow the consonant or consonant cluster. These marks can appear above, below, or to the left of the main character. Interestingly, many dependent vowels have two different pronunciations. The specific sound often depends on the inherent vowel of the consonant they are attached to.

Consonant clusters are handled through a process called stacking. When two or more consonants are pronounced consecutively without a vowel between them, they form a cluster. Khmer clusters usually consist of two consonants, though some words contain three. To write these, the script uses a subscript form for the second and third consonants. In Khmer, this subscript is called a "foot of a letter" (cheung akshar).

The main consonant is written first. The subscript consonant is then placed directly below it. While most subscripts look like a smaller version of the original letter, some are simplified. A few subscripts may appear to the left or have ascending elements to the right. This stacking system allows complex sounds to be represented compactly.

Modern Khmer uses 33 consonant characters. This is a reduction from the original 35 characters used in the past. The two missing characters have become obsolete. Some consonants are considered "dominant," such as stops and fricatives. These dominant sounds affect how following dependent vowels are pronounced in a cluster. If two consonants in a cluster are both dominant, the subscript consonant determines the vowel's pronunciation. There are also supplementary consonants used for loanwords. These are often used for words borrowed from French or Thai. Some of these are digraphs, created by stacking a subscript under a letter and adding a specific diacritic. For example, the character for "pâ" is formed using the "mouse teeth" diacritic (musĕkâtônd) over a consonant.

The history of the Khmer script traces back to ancient India. It was adapted from the Pallava script, which was used in southern India and Southeast Asia during the 5th and 6th centuries AD. The Pallava script itself descended from the Tamil-Brahmi script.

The oldest dated Khmer inscription was discovered in the Angkor Borei District of Takéo Province. This inscription dates back to the year 611. Throughout the former Khmer Empire, stelae have been found in areas like the Mekong Delta, southern Laos, and central Thailand. These inscriptions show slight differences between those written in Sanskrit and those written in Khmer. These two distinct systems eventually evolved into the modern styles of the script.

Historical records provide evidence of the script's long-standing identity. The oldest known record of the name "Khmer Script" (អក្សរខ្មែរ) is found in inscription K.362. This inscription dates to the late 9th century during the reign of King Yasovarman I. It contains the Sanskrit term "Kāmvujākṣara," written in Old Khmer as "កម្វុជាក្សរ." This proves that the Khmer people had a specific name for their writing system as early as the 9th century. While modern Khmer differs from the inscriptions found at the ruins of Angkor, the connection to the past remains strong. The script has evolved from sacred use to general daily use.

The Khmer script has also had a profound influence on its neighbors. The Thai and Lao scripts are direct descendants of an older cursive form of the Khmer script. They developed through the Sukhothai script. This shows how writing systems can spread and transform across different regions and cultures. Today, the script remains a vital part of the linguistic landscape of Southeast Asia. It connects modern Cambodians to their ancient history and to the religious traditions of the region.
