When two or more morphemes occur together to form a word then sometimes there is some change in the phonemic shape of the morphemes. Such kinds of changes are dealt with in this section. The most general morphonemic changes will be dealt here in this section and irregular alternates are dealt within the Morphology section.
 

Intervocalic or final vowel of at least a disyllabic stem in XCV(C) position is dropped when followed by a suffix beginning with a vowel in the word formation. This may cause some new consonant cluster formation.
 

Two identical or similar vowels cannot occur together in a single word with the result when the stem final vowel V is followed by an identical vowel with or without over tones in the formation of a word then the preceding V is dropped.
 

Examples are:
 

Except the above mentioned examples when the /a/ ending verb stems are followed by /ã/ suffix then /w/ comes in between.
