Excerpt: Doubly articulated consonants are consonants with two simultaneous primary places of articulation of the same manner (both plosive, or both nasal, etc.). They are a subset of co-articulated consonants. They are to be distinguished from co-articulated consonants with secondary articulation, that is, a second articulation not of the same manner. An example of a doubly articulated consonant is the voiceless labial-velar plosive, which is a and a pronounced simultaneously. On the other hand, the voiceless labialized velar plosive has only a single stop articulation, velar (), with a simultaneous approximant-like rounding of the lips. In some dialects of Arabic, the voiceless velar fricative has a simultaneous uvular trill, but this is not considered double articulation either. There are four independently controllable articulations that may double up in the same manner of articulation: labial, coronal, dorsal, and radical. (The glottis controls phonation, and works simultaneously with many consonants. It is not normally considered an articulator, and an ejective, with simultaneous closure of the velum and glottis, is not considered a doubly articulated consonant.) Approximants such as and may be either doubly or secondarily articulated. For example, in English, is a labialized velar that could be transcribed as, but the Japanese is closer to a true labial-velar . However, it is normal practice to use phonetic and for the labialized approximants, and some linguists restrict the symbols to that usage. (See the article on approximants.)
