Korean is the official language of both North and South Korea. The language is also one of the two official languages (the other is Standard Mandarin) in neighbouring Yanbian, China. Worldwide, there are around 78 million Korean speakers, including large groups in the former Soviet Union, China, Australia, the United States, Canada, Brazil, Japan, and more recently the Philippines. The genealogical classification of Korean is debated. Many linguists place it in the Altaic language family; some others consider it to be a language isolate. Korean is agglutinative in its morphology and SOV in its syntax. Some vocabulary has been imported from Chinese, or created on Chinese models.
