 Labiodental affricates are reported in Tsonga which would require the stop portion of the affricate to be a labiodental stop, though Ladefoged and Maddieson (1996) raise the possibility that labiodental affricates involve a bilabial closure like "pf" in German.Unlike plosives and affricates, labiodental nasals are common across languages.Linguolabial consonants are made with the blade of the tongue approaching or contacting the upper lip.
