Prenasalized consonant

Prenasalized consonants are phonetic sequences of a nasal and an obstruent (or occasionally a non-nasal sonorant such as [ɺ]) that behave phonologically like single consonants. The primary reason for considering these to be single consonants, rather than clusters as in English finger or member, lies in their behavior; however, there may also be phonetic correlates which distinguish prenasalized consonants from clusters. Because of the additional difficulty in both articulation and timing, prenasalized fricatives and sonorants are not as common as prenasalized stops or affricates, and the presence of the former implies the latter.
