Topic: Adjective (বিশেষণ),

Best Answer Explained in Below-:

In the sentence "He is a 'better' worker than I," the word "better" functions as an adjective. Adjectives are words that describe or modify nouns, providing more information about their qualities. In this case, "better" modifies the noun "worker," allowing us to understand the quality being attributed to him compared to another worker (the speaker).

The use of "better" indicates a comparison of proficiency or skill level between two individuals in the role of a worker. Here, "better" is the comparative form of the adjective "good," which is used to compare two subjects. In English, comparative adjectives typically end in "-er" or are preceded by "more," but they still fall under the adjective category because they describe the characteristics of a noun.

The structure of the sentence shows that "better" plays a crucial role in establishing the relationship between the two subjects (he and I), making it clear that one is performing at a superior level in the context of work, thus reinforcing the classification of "better" as an adjective.
