Co-articulated consonants or complex consonants are consonants produced with two simultaneous

places of articulation In articulatory phonetics, the place of articulation (also point of articulation) of a consonant is a location along the vocal tract where its production occurs. It is a point where a constriction is made between an active and a passive articula ...

. They may be divided into two classes: doubly articulated consonants with two primary places of articulation of the same manner (both stop, or both nasal, ''etc''.), and consonants with

secondary articulation In phonetics, secondary articulation occurs when the articulation of a consonant is equivalent to the combined articulations of two or three simpler consonants, at least one of which is an approximant. The secondary articulation of such co-articu ...

Doubly articulated consonants

An example of a doubly articulated consonant is the
