Explanation:

Each prefix changes the meaning of the base word. For example:
- un- negates the meaning (e.g., unwell means not well).
- dis- often indicates separation or reversal (e.g., disobey means not to obey).
- im- is used with Latin roots to negate (e.g., imperfect means not perfect).

This exercise helps in understanding how prefixes modify the meanings of words, which is a fundamental skill in English vocabulary building.
