Pame grammar is characterized by complex morphophonemics and suppletion. The latter, Harris termed "extended morphophonemics". Enrico (2003) uses for some instances of based on morphophonemics. Stankiewicz is best known for his research on Slavic accentology and morphophonemics. See further remarks regarding the oral/nasal nature of affixes in the Morphophonemics section. Chomsky completed his undergraduate thesis "The Morphophonemics of Modern Hebrew" in 1949. Chomsky's original work was in morphophonemics. Inflected and agglutinating languages may have extremely complicated systems of morphophonemics. Chomsky's BA honors thesis, "Morphophonemics of Modern Hebrew", applied Harris's methods to the language.
