Xhosa /ˈkoʊsə/ is one of the official languages of South Africa. Xhosa is spoken by approximately 7.9 million people, or about 18% of the South African population. Like most Bantu languages, Xhosa is a tonal language, that is, the same sequence of consonants and vowels can have different meanings when said with a rising or falling or high or low intonation. One of the most distinctive features of the language is the prominence of click consonants; the word "Xhosa" begins with a click. Wikipedia
