Consonant classes

Now you will learn about several types of consonant sounds and the way they are classified.

Homorganic Sounds

When two sounds have the same place of articulation, they are said to be homorganic. For example, [d] and [n] are homorganic because both of them are articulated on the alveolar ridge. [p, b, m] are homorganic because they are bilabial.


Stops which are made with a glottalic egressive airstream mechanism. The diacritic indicating an ejective is an apostrophe [l'] placed after a symbol. For example, [k’] in Hausa words:

  • [k'a:ra] “increase”
  • [ka:ra] “put near”



Implosives are stops which are made with an ingressive airstream mechanism. While producing implosives, there is a downward movement of the larynx to suck air inward. Historically, languages seem to develop implosives from plosives that have become more and more voiced.
