What is the primary function of a preposition in a sentence?

The primary function of a preposition in a sentence is to show relationships of time or location. Prepositions are words like "in," "on," "at," "between," and "during," which help to clarify where something is in relation to something else, or when something happens. For instance, in the sentence "The book is on the table," the preposition "on" indicates the relationship between the book and the table, specifying the location of the book. Similarly, in phrases like "during the meeting," the preposition "during" indicates the time frame in which the action takes place. This function is essential in providing context and clarity to sentences, helping the reader understand spatial and temporal relationships more clearly.

The other choices represent different functions that are not applicable to prepositions. Some convey actions, while others may involve modifying nouns or connecting clauses, but these do not define the role of prepositions within sentence structure.
