What is the function of a preposition?

To show action
To indicate a noun's relationship to another word
To serve as a subject
To link two ideas

The correct answer is: To indicate a noun's relationship to another word

The function of a preposition is to indicate a noun's relationship to another word within a sentence. Prepositions are crucial in establishing connections between various elements of a sentence, such as where something is located, when something happens, or the direction of an action. For instance, in the phrase "The book is on the table," the preposition "on" shows the relationship between "book" and "table," clarifying the location of the book. The other options represent different grammatical functions. Showing action relates more to verbs, which convey the actions or states of being. Serving as a subject pertains to the role of a noun or pronoun in a sentence that performs the action of the verb. Linking two ideas typically refers to conjunctions, which connect clauses or phrases rather than indicating relationships between nouns or pronouns.
