That is your house. The underlined word is :

Question

Accepted Answer

The underlined word in the sentence "That is your house." is "your." Let's analyze why Option 2, "Pronoun," is the correct answer and why the other options are incorrect.

1. **Explanation for Option 2 (Pronoun):**
   - The word "your" is a possessive pronoun. Possessive pronouns are used to indicate ownership or possession. In this sentence, "your" shows that the house belongs to the person being addressed. Pronouns replace nouns or noun phrases, and possessive pronouns specifically indicate who owns something. Therefore, "your" functions as a pronoun in this context, justifying why Option 2 is correct.

2. **Why Option 1 (Noun) is incorrect:**
   - A noun is a word that represents a person, place, thing, or idea. In the sentence, "house" is the noun because it is the thing being referred to. "Your" does not represent a person, place, thing, or idea; instead, it indicates possession. Therefore, "your" is not a noun.

3. **Why Option 3 (Preposition) is incorrect:**
   - A preposition is a word used to show the relationship of a noun or pronoun to another word in the sentence, often indicating location, direction, or time. Examples include "in," "on," "at," etc. "Your" does not function as a preposition because it does not show any relationship between words in terms of location, direction, or time.

4. **Why Option 4 (Adverb) is incorrect:**
   - An adverb modifies a verb, adjective, or another adverb, often indicating how, when, where, or to what extent something happens. "Your" does not modify any verb, adjective, or adverb in the sentence. It simply indicates possession, which is not the function of an adverb.

In conclusion, the word "your" is correctly identified as a pronoun, specifically a possessive pronoun, which is why Option 2 is the correct answer. The other options do not accurately describe the grammatical role of "your" in the sentence.
