Identify the underlined part of speech in the following sentence : He came before the appointed time.

Question

Accepted Answer

The underlined word "before" in the sentence "He came before the appointed time" is identified as a preposition, which is Option 4. Here is a detailed explanation justifying why Option 4 is correct and why the other options are incorrect:

1. **Explanation for Option 4 (Preposition):**
   - A preposition is a word that shows the relationship between a noun or pronoun and other words in a sentence. In this sentence, "before" is used to indicate the relationship between "he came" and "the appointed time." It specifies the time relationship, showing that the action of coming occurred prior to the appointed time. Therefore, "before" functions as a preposition, making Option 4 the correct choice.

2. **Explanation for why Option 1 (Adverb) is incorrect:**
   - An adverb modifies a verb, adjective, or other adverb, often indicating manner, place, time, or degree. While "before" can function as an adverb in other contexts (e.g., "He had seen her before"), in this sentence, it does not modify the verb "came" directly but rather connects the action to a specific time. Thus, it is not acting as an adverb here.

3. **Explanation for why Option 2 (Conjunction) is incorrect:**
   - A conjunction is a word used to connect clauses or sentences or to coordinate words in the same clause. Examples include "and," "but," and "or." "Before" can function as a conjunction in sentences like "He left before I arrived," where it connects two clauses. However, in the given sentence, "before" does not connect two independent clauses but rather introduces a prepositional phrase ("before the appointed time"), making it a preposition, not a conjunction.

4. **Explanation for why Option 3 (Noun) is incorrect:**
   - A noun is a word that represents a person, place, thing, or idea. "Before" is not functioning as a noun in this sentence. It does not name a person, place, thing, or idea but instead indicates a temporal relationship. Therefore, it cannot be classified as a noun in this context.

In conclusion, the word "before" in the sentence is correctly identified as a preposition because it establishes a temporal relationship between the action of coming and the appointed time. This supports Option 4 as the correct answer.
