Term	Definition
Nasal Assimilation	A type of consonant assimilation (or consonant harmony) in which a non-nasal sound is replaced with a nasal sound that is similar to another nasal sound in the word. Alveolar refers to the alveolar ridge, which is the ridged or bumpy section of the hard palate in the mouth located just behind the top two front teeth. For example, the word soup has the consonants /s/ (alveolar) and /p/ (non-alveolar). Alveolar assimilation occurs when the /p/ is changed to an alveolar sound to assimilate, or conform to, the voiceless /s/. The result would sound like /sout/, with the /t/ (alveolar) replacing the /p/ (non-alveolar). See also Assimilation, Phonological Processes, Alveolar
