Cambodian is the official language of Cambodia, and is also sometimes known as Khmer.
Cambodian text is written from left to right, like English, but uses a very different set of characters. The Cambodian writing system uses a syllabic alphabet, meaning that each character represents a consonant sound followed by an inherent vowel sound, which can be changed by adding diacritic marks. Vowels can also be written as independent characters. In addition, each consonant has a subscript form that can be attached to other characters to form consonant clusters. These subscript consonants are sometimes called "consonant feet" or "coeng consonants".
You may have some transliterated Cambodian content in addition to content which uses the actual Cambodian characters. Transliterated content can help you master vocabulary and pronunciation before tackling a new writing system.
You do not have to type actual Cambodian characters in transliterated Cambodian content. You can type the transliterations anywhere typed answers are required.
The transliterated Cambodian content may use a variety of special characters to indicate certain sounds. To type these characters, type the base character for the letter you want, then select the special character from the set of characters which appears. See Typing accents or special characters for details.
