What is the Difference Between Adjective and Determiner?

The main difference between an adjective and a determiner lies in their positioning and function within a sentence. Both adjectives and determiners describe nouns and provide more information about them, but they have distinct roles and positions in a sentence. Here are the key differences:

1. Position: Adjectives can be used both before and after the noun they modify, while determiners can only be used before the noun. For example, in the sentence "The brown dog sleeps," "brown" is an adjective that can be used before or after the noun "dog," while "the" is a determiner that can only be used before the noun.
2. Quantity: A noun can have an unlimited number of adjectives, but it can have only one determiner. For instance, in the phrase "I want the some apple," using both "some" and "the" as determiners would be incorrect because a noun can have only one determiner.
3. Comparative Forms: Adjectives can have comparative forms (e.g., "prettier" is the comparative form of "pretty"), but determiners cannot have comparative forms.
4. Class: Determiners are a closed class, meaning there are a limited number of them in the English language, whereas adjectives are an open class, and new adjectives can be created or used.

In summary, adjectives and determiners both describe nouns, but they have different positions, quantities, and forms within a sentence. Adjectives can be used both before and after nouns and can have comparative forms, while determiners can only be used before nouns and cannot have comparative forms. Determiners are a closed class, while adjectives are an open class.

Comparative Table: Adjective vs Determiner

Here is a table comparing the differences between adjectives and determiners:

Adjectives and determiners both describe nouns and provide more information about them. However, they have different functions, positioning, and use. Adjectives can be used both before and after nouns, while determiners can only be used before nouns. A noun can have multiple adjectives, but it can have only one determiner.
