Khoekhoe language
Nama is seen as having three or four tones, /á, ā, à/ or /a̋, á, à, ȁ/, that may take place on different mora (vowels and final nasal consonants). The high sound is higher when it takes place on one of the high vowels (/í ú/) or on a nasal (/ń ḿ/) than on mid or low vowels (/é á ó/).
