Here are some examples:
* The *red* car is fast. (The adjective "red" modifies the noun "car")
* He is *happy* with his new job. (The adjective "happy" modifies the pronoun "he")
* The *tall* building has many windows. (The adjective "tall" modifies the noun "building")
Adjectives can modify nouns and pronouns in various ways, including:
* Describing a quality: *beautiful*, *old*, *strong*
* Identifying a specific type or category: *wooden*, *French*, *digital*
* Indicating a quantity: *many*, *few*, *several*
* Expressing an opinion: *amazing*, *terrible*, *boring*
Note: Adjectives can also be used as predicates, where they describe the subject of a sentence. For example:
* The flowers are *beautiful*. (The adjective "beautiful" is the predicate of the sentence)
In summary: Adjectives play a crucial role in grammar by adding detail and specificity to nouns and pronouns, enriching our understanding of the words they modify.
