Cambodian: An Essential Grammar is an accessible guide to the grammatical themes, patterns, and structures of the Cambodian language. Across 14 chapters, the book introduces both basic and more complex examples in the written and spoken language. With its use of plain language and avoidance of complicated linguistic jargon, this is an accessible and user-friendly grammar. Examples are presented in Cambodian, English, and Romanized transliteration scripts, and draw on up-to-date data from the colloquial speech of Cambodian people in a wide variety of contexts. This is a key reference for all students, professionals, researchers, and general readers wishing to advance their Cambodian grammar from beginner level and is designed for both independent and class-based studies.
