Yes, because it can be used to show relationships between nouns and adjectives with other words in the sentence. Consider the following sentence: "Once upon a time there lived a tyrannical king." The "Once" in this sentence explains when this happened and shows a logical relationship with "upon a time." If you still don't comprehend why "once" is a preposition consider this sentence: "Jackie placed an ancient book, with leather bindings, inside her rugged book bag." In this sentence "inside" is the preposition because it's telling where the book was placed. "Inside" shows a clear relationship between the book and the book bag. A preposition could be a verb, noun, or pronoun.
