Place of articulation identifies where speech articulators form a constriction or closure. A description can specify an active articulator, such as the tongue, and the surface it approaches. A bilabial consonant uses both lips; a labiodental consonant uses the lower lip and upper teeth; a velar consonant involves the back of the tongue near the soft palate.^[ref]

For example, [f] and [v] share a labiodental location, while their typical voicing classifications differ. Conversely, describing a sound as a fricative specifies manner of articulation without identifying which constriction produces it. The paired descriptions make the physical classification more informative.

The place is an approximate region and relation between articulators, rather than a single universal coordinate in the mouth. Neighboring sounds can change the detailed movement while leaving the broad category useful.

A velar consonant forms its main constriction between the back of the tongue and the soft palate. The label identifies a place of articulation. The soft palate's separate role in controlling the nasal airflow route means that velar place does not itself imply a nasal manner of articulation.^[ref]

The sounds [k] and [g] are velar oral stops, while [ŋ] is a velar nasal consonant. All involve a similar oral constriction region, but they differ in airflow route and usual voicing. The precise contact position can also shift with neighboring vowels. Describing a region of contact is therefore more informative than imagining one fixed point used identically in every utterance.
