Final answer:
In the sentence, 'The tall tree at the end of the road is blooming magnificently,' the word 'tall' functions as an adjective, since it describes the noun 'tree.'
Step-by-step explanation:
The word functioning as an adjective in the sentence “The tall tree at the end of the road is blooming magnificently” is D) tall. An adjective is a word that modifies, or describes, a noun or pronoun. In the given sentence, “tall” describes the noun “tree”, telling us more about the tree's appearance. Other options do not serve as adjectives: “end” is a noun, “blooming” is a verb in this context, and “magnificently” is an adverb modifying the verb “blooming”.
As seen in the examples provided for reference, adjectives play a crucial role in adding detail and imagery to descriptions. In “Loveliest of Trees, the cherry now…”, adjectives such as “white” describe the “wearing” (appearance) of the trees. Likewise, in “The soft and damp pink-flowers of the Dogwood tree…” the adjectives “soft,” “damp”, and “pink” paint a vivid picture of the Dogwood tree's flowers.
