context_page_description: Khmer is the language of the Khmer people and the official language of Cambodia. With approximately 16 million speakers, it is the second most widely spoken Austroasiatic language. Khmer has been influenced considerably by Sanskrit and Pali, especially in the royal and religious registers, through Hinduism and Buddhism. The more colloquial registers have influenced, and have been influenced by, Thai, Lao, Vietnamese, and Cham, all of which, due to geographical proximity and long-term cultural contact, form a sprachbund in peninsular Southeast Asia. It is also the earliest recorded and earliest written language of the Mon–Khmer family, predating Mon and by a significant margin Vietnamese, due to Old Khmer being the language of the historical empires of Chenla, Angkor and, presumably, their earlier predecessor state, Funan.
  The vast majority of Khmer speakers speak Central Khmer, the dialect of the central plain where the Khmer are most heavily concentrated. Within Cambodia, regional accents exist in remote areas but these are regarded as varieties of Central Khmer.
context_section_description: Khmer is written with the Khmer script, an abugida developed from the Pallava script of India before the 7th century when the first known inscription appeared. Written left-to-right with vowel signs that can be placed after, before, above or below the consonant they follow, the Khmer script is similar in appearance and usage to Thai and Lao, both of which were based on the Khmer system. The Khmer script is also distantly related to the Mon script, the ancestor of the modern Burmese script. Within Cambodia, literacy in the Khmer alphabet is estimated at 77.6%.
  Consonant symbols in Khmer are divided into two groups, or series. The first series carries the inherent vowel /ɑː/ while the second series carries the inherent vowel /ɔː/. The Khmer names of the series, /aʔkʰosaʔ/ ('voiceless') and /kʰosaʔ/ ('voiced'), respectively, indicate that the second series consonants were used to represent the voiced phonemes of Old Khmer.  As the voicing of stops was lost, however, the contrast shifted to the phonation of the attached vowels, which, in turn, evolved into a simple difference of vowel quality, often by diphthongization.  This process has resulted in the Khmer alphabet having two symbols for most consonant phonemes and each vowel symbol having two possible readings, depending on the series of the initial consonant:
