Un and in are prefixes that are commonly used in English. They can change the meaning of a word, often in opposite ways. For example, “unhappy” means the opposite of “happy,” and “inactive” means the opposite of “active.” Un and in prefixes can also be used to create new words, such as “unbutton” and “install.”

Question 1:
How are un- and in- prefixes different in their meaning and impact on the root word?
Answer:
The prefix “un-” indicates negation or reversal, converting adjectives or verbs into their opposites. For instance, “unhappy” means not happy, and “undo” means to reverse an action. Conversely, the prefix “in-” generally implies negation, lack, or deficiency. It transforms adjectives and nouns into words describing the absence or inadequacy of a quality or state. For example, “incapable” signifies a lack of ability, and “insufficient” indicates an inadequacy of quantity or quality.
Question 2:
What are the distinct roles of un- and in- prefixes in forming antonyms?
Answer:
The un- prefix creates antonyms by directly negating the meaning of the root word. For instance, “unhappy” is the antonym of “happy” because it negates the positive emotion of happiness. In contrast, the in- prefix forms antonyms by suggesting a deficiency or lack of a particular quality or condition. An example is “incapable,” which implies a lack of capability or ability, making it the antonym of “capable.”
Question 3:
How do un- and in- prefixes affect the part of speech of the root word?
Answer:
The un- prefix typically does not alter the part of speech of the root word. For instance, “unhappy” remains an adjective like its root word “happy.” However, the in- prefix can sometimes change the part of speech. For example, the noun “capacity” becomes the adjective “incapable” when the in- prefix is added, negating its inherent capacity or ability.
