クシ語派
Most Cushitic languages have a simple five-vowel system with phonemic length (); a notable exception are the Agaw languages, which do not contrast vowel length, but have one or two additional central vowels. The consonant inventory of many Cushitic languages includes glottalic consonants, e.g. in Oromo, which has the ejectives and the implosive . Less common are pharyngeal consonants , which appear e.g. in Somali or the Saho–Afar languages.
