The Khmer script (Khmer: អក្សរខ្មែរ; IPA: [ʔaʔsɑː kʰmaːe]) is an abugida (alphasyllabary) script used to write the Khmer language (the official language of Cambodia). It is also used to write Pali among the Buddhist liturgy of Cambodia and Thailand.
It was adapted from the Pallava script, a variant of Grantha alphabet descended from the Brahmi script of India. The oldest dated inscription in Khmer was found at Angkor Borei District in Takéo Province south of Phnom Penh and dates from 611. The modern Khmer script differs somewhat from precedent forms seen on the inscriptions of the ruins of Angkor.
