The Old Khmer Grammar has been brewed from a mass of memoranda and citations accumulated over long years of teaching Old Khmer to a succession of able graduate students. It is meant to serve the immediate needs of readers embarking on the study of the inscriptions, and assumes that they have some acquaintance with modern Khmer. Designed for easy reference, it addresses the main points of grammar and style in the great majority of the texts. A few matters of special interest not previously brought to public notice are discussed in fair detail. Included are a bibliography designed to assist students, and a lexicon of Old Khmer words occurring in the text.

It can be considered a companion volume to Prof. Jenner's A Dictionary of pre-Angkorian Khmer and A Dictionary of Angkorian Khmer.
