What are the similarities of the Derivational and Inflectional affixes?

Derivational and inflectional affixes both serve to modify Words and create new forms. They are added to base Words to alter their meaning or grammatical function. Both types of affixes can change a Word's category; for example, adding a derivational suffix can transform a noun into a verb, while inflectional suffixes modify a Word's tense or number without changing its category. Additionally, both are integral to the morphological structure of a language, helping to convey meaning and grammatical relationships.
