What grammatical form does the word "better" indicate?

The word "better" indicates the comparative form of an adjective. In English grammar, comparative adjectives are used to compare differences between the two objects they modify. "Better" compares one thing with another, suggesting that something possesses a greater degree of a particular quality than another is. For example, in the sentence "She is better at math than her brother," "better" is being used to compare the abilities of two individuals regarding math.

In contrast, the superlative form, which the first choice refers to, would involve a comparison of three or more items. An example of a superlative would be "best," indicating the highest degree of quality among several subjects.

The infinitive form appears in the base form of a verb preceded by "to," such as "to run" or "to think." This is unrelated to adjectives or comparative forms.

Present tense, on the other hand, relates to verb forms that indicate current actions or states. Thus, "better" fits squarely into the comparative category, demonstrating the relationship between entities by indicating a higher degree of comparison.
