text: # Bilabial stop
  
  In phonetics and phonology, a bilabial stop is a type of consonantal sound, made with both lips (hence bilabial), held tightly enough to block the passage of air (hence a stop consonant). The most common sounds are the stops [p] and [b], as in English pit and bit, and the voiced nasal [m]. More generally, several kinds are distinguished:
  
  * [p], voiceless bilabial plosive
  * [b], voiced bilabial plosive
  * [m], voiced bilabial nasal
  * [m̥], voiceless bilabial nasal
  * [ɓ], voiced bilabial implosive
  * [pʼ], bilabial ejective (rare)
  * [ɓ̥] or [pʼ↓], voiceless bilabial implosive (very rare)
