* Pronouns: "The happy one" (modifies the pronoun "one")
* Adverbs: "Very quickly" (modifies the adverb "quickly")
* Other adjectives: "Incredibly beautiful" (modifies the adjective "beautiful")
* Clauses: "The house, expensive though it was, was still worth buying" (modifies the entire clause)
* Sentences: "He was tired." (modifies the entire sentence)
It's important to note that in some cases, adjectives may appear to modify a verb, but they actually modify a noun or pronoun implied in the sentence. For example, in the sentence "He ran fast," the adjective "fast" actually modifies the implied noun "speed" ("He ran at a fast speed").
Therefore, while adjectives are most commonly found in noun phrases, they can also modify other parts of speech and even sentences as a whole.
