Consonants
In linguistics, a consonant is a speech sound that is produced by a constriction or closure of the vocal tract, impeding the flow of air from the lungs. Consonants are classified based on the manner and place of articulation, as well as the voicing or voicelessness of the sound.
Manner of Articulation
- Stops: Produced by completely blocking the airflow in the vocal tract. Examples include /p/, /t/, /k/, /b/, /d/, /g/.
- Fricatives: Produced by a narrow constriction in the vocal tract, causing the air to create friction. Examples include /f/, /v/, /θ/, /ð/, /s/, /z/, /ʃ/, /ʒ/.
- Affricates: A combination of a stop and a fricative. Examples include /tʃ/, /dʒ/.
- Nasals: Produced by allowing air to flow through the nose. Examples include /m/, /n/, /ŋ/.
- Liquids: Produced by creating a partial obstruction in the vocal tract, causing the air to flow around the obstruction. Examples include /l/, /r/.
- Semi-vowels: Produced by a less constricted vocal tract than vowels, allowing a significant amount of airflow. Examples include /j/, /w/.
Place of Articulation
- Bilabial: Produced by bringing the two lips together. Examples include /p/, /b/, /m/.
- Labiodental: Produced by bringing the lower lip to the upper teeth. Examples include /f/, /v/.
- Dental: Produced by placing the tongue against the back of the front teeth. Examples include /θ/, /ð/.
- Alveolar: Produced by placing the tongue against the alveolar ridge. Examples include /t/, /d/, /s/, /z/, /n/.
- Retroflex: Produced by curling the tongue back towards the roof of the mouth. Examples include /ʈ/, /ɖ/, /ɳ/.
- Palatal: Produced by placing the tongue against the hard palate. Examples include /ʃ/, /ʒ/, /j/.
- Velar: Produced by placing the tongue against the soft palate. Examples include /k/, /g/, /ŋ/.
- Uvular: Produced by placing the tongue against the uvula. Examples include /q/, /ɢ/.
- Pharyngeal: Produced by constricting the pharynx. Examples include /ħ/, /ʕ/.
- Glottal: Produced by constricting the vocal cords. Examples include /h/, /ʔ/.
Voicing
- Voiced: Produced with the vocal cords vibrating. Examples include /b/, /d/, /g/, /v/, /z/, /ʒ/, /m/, /n/, /ŋ/, /l/, /r/, /j/, /w/.
- Voiceless: Produced without the vocal cords vibrating. Examples include /p/, /t/, /k/, /f/, /s/, /ʃ/, /θ/, /h/, /ʔ/.
