Editing Bilabial consonant

{{Short description|Consonant articulated with both lips}}
{{IPA notice}}
In [[phonetics]], a '''bilabial consonant''' is a [[labial consonant]] [[place of articulation|articulated]] with both [[lip]]s.

== Frequency ==
Bilabial consonants are very common across languages. Only around 0.7% of the world's languages lack bilabial consonants altogether, including [[Tlingit language|Tlingit]], [[Chipewyan language|Chipewyan]], [[Oneida language|Oneida]], and [[Wichita language|Wichita]],<ref>{{ citation | last= Maddieson | first= Ian | date=2008 | chapter= Absence of Common Consonants | editor1-last= Haspelmath | editor1-first= Martin | editor2-last= Dryer | editor2-first= Matthew S. |editor3-last= Gil | editor3-first= David |editor4-last= Comrie |editor4-first= Bernard |title= The World Atlas of Language Structures Online |place= Munich |publisher= Max Planck Digital Library | chapter-url= http://wals.info/feature/18}}</ref> though all of these have a labial–velar approximant /w/.

==Varieties==
The bilabial consonants identified by the [[International Phonetic Alphabet]] (IPA) are:

== Other varieties ==
The [[extensions to the IPA]] also define a '''{{vanchor|bilabial percussive}}''' ({{IPAblink|ʬ|audio=y}}) for [[percussive consonant|smacking the lips together]]. A lip-smack in the non-percussive sense of the lips audibly parting would be {{IPA|[ʬ↓]}}.<ref>{{cite book |last=Heselwood |first=Barry |title= Phonetic Transcription in Theory and Practice |year=2013 |page=121 |doi=10.3366/edinburgh/9780748640737.001.0001 |publisher=Edinburgh University Press |jstor=10.3366/j.ctt9qdrqz|isbn=978-0-7486-4073-7 |s2cid=60269763 }}</ref>

The [[IPA chart]] shades out ''bilabial lateral consonants'', which is sometimes read as indicating that such sounds are not possible. The fricatives {{IPA|[ɸ]}} and {{IPA|[β]}} are often lateral, but since no language makes a distinction for centrality, the allophony is not noticeable.
