Until its extinction, Ubykh may have been the language with the most fricatives (29 not including ), some of which did not have dedicated symbols or diacritics in the IPA. This number actually outstrips the number of all consonants in English (which has 24 consonants). By contrast, approximately 8.7% of the world's languages have no phonemic fricatives at all. This is a typical feature of Australian Aboriginal languages, where the few fricatives that exist result from changes to plosives or approximants, but also occurs in some indigenous languages of New Guinea and South America that have especially small numbers of consonants. However, whereas is "entirely" unknown in indigenous Australian languages, most of the other languages without true fricatives do have in their consonant inventory.
