In the sentence "The swift bird flew by," the word "by" functions as a preposition. Prepositions are words that typically link nouns, pronouns, or phrases to other words within a sentence, often indicating relationships of direction, location, or time. In this example, "by" indicates the manner in which the bird flew, suggesting a movement close to or past something. The prepositional nature of "by" highlights this relationship, connecting the action of flying to the surrounding context without directly pointing to a specific object.

Other parts of speech do not apply in this context. For instance, conjunctions are used to connect clauses or sentences, nouns serve as the names of people, places, or things, and adverbs typically modify verbs, adjectives, or other adverbs. In this case, "by" does not fulfill any of those roles, reinforcing its identification as a preposition.
