The key characteristic of a preposition is that it indicates a relationship between nouns or pronouns. Prepositions are words that link nouns, pronouns, or phrases to other words within a sentence, establishing a connection that describes various aspects such as direction, location, time, and manner. For example, in the phrase "The book is on the table," the preposition "on" shows the relationship between "book" and "table," clarifying where the book is positioned.

Understanding prepositions is crucial for effective sentence construction because they help create clear, meaningful relationships between different elements of a sentence, enabling the reader to understand the overall context. This function distinguishes prepositions from other parts of speech, such as verbs, which express action, or conjunctions, which connect clauses.
