Final answer:
Affixes can be classified based on their position with respect to the Morphological structure.
Step-by-step explanation:
Affixes can be classified based on their position with respect to the Morphological structure. Morphology is the study of how words are formed, including the way affixes (prefixes and suffixes) are attached to base words. In English, for example, the prefix 'un-' is added to a base word to create a new word with the opposite meaning, such as 'unhappy'. This classification is important in understanding how words are built and how meaning can be changed through the addition of affixes.
