|Places of articulation|
In Australian linguistics, the peripheral consonants are a natural class encompassing consonants articulated at the extremes of the mouth: labials and velars. That is, they are the non-coronal consonants. In Australian languages, these consonants pattern together both phonotactically and acoustically. In Arabic and Maltese philology, the moon letters transcribe non-coronal consonants, but they do not form a natural class.
Australian languages typically favour peripheral consonants word- and syllable-initially, while they are not allowed or are rare word- and syllable-finally. This is diametrically opposed to the apicals.
