Derivational and Inflectional Morphology
If the addition of an affix (prefix or suffix) changes the category of the word,
the process is called derivational morphology.  If the addition of the affix does not change
the category of the word, it is called inflectional morphology. For example, in English
to add 'ism' to 'magnet' changes 'magnet' to 'magnetism' yet both are still nouns.  
Thus, the addition of "ism" is said to be inflected.  However, to add 'ize' to make 'magnetize'
turns the noun into a verb which is a derivational process.
     Because affixes play such an important role in Dena'ina grammar, the process of inflectional
and derivational verb morphology is extremely important in Dena'ina.  
These features give the language the basis for its rich nuance of meaning.
