Substitution of One Part of Speech for Another

Adjective to Noun

Step 1: In 'Susan felt proud', 'proud' is an adjective describing Susan's feeling. Step 2: In 'Susan took pride', 'pride' is a noun (a thing/concept). Step 3: The adjective 'proud' has been converted to the noun 'pride'. Step 4: This is an adjective to noun conversion. The other options are incorrect as we're not dealing with verbs or adverbs here.

Adverb

Step 1: Identify what 'fast' is modifying in the sentence. Step 2: 'Fast' describes how Dheer ran, so it modifies the verb 'ran'. Step 3: Words that modify or describe verbs are called adverbs. Step 4: Therefore, 'fast' is an adverb. It's not a noun (doesn't name), verb (doesn't show action), or adjective (doesn't describe a noun directly).

fast

Step 1: In 'Dheer ran fast', 'fast' is an adverb modifying the verb 'ran'. Step 2: In 'Dheer was a fast runner', 'fast' is an adjective describing the noun 'runner'. Step 3: The same word 'fast' changes function from adverb to adjective. Step 4: This shows how the same word can function as different parts of speech depending on context. Other words in the sentence don't show this conversion.

Adjective

Step 1: Identify what 'wise' is describing in the sentence. Step 2: 'Wise' describes the quality of the man, giving information about his character. Step 3: Words that describe or modify nouns (like 'man') are adjectives. Step 4: Therefore, 'wise' is an adjective. It's not a noun (doesn't name something), verb (doesn't show action), or adverb (doesn't modify a verb).
