Which of the following is a part of speech that shows the relationship of a noun to another word?

A preposition is the part of speech that establishes relationships between nouns (or pronouns) and other words in a sentence. It typically indicates spatial, temporal, or directional relationships, helping to provide context and clarity. Prepositions often answer questions such as "where?" "when?" and "how?" by linking nouns to other elements in a phrase or sentence.

For example, in the phrase "The book is on the table," the preposition "on" shows the relationship between "book" and "table." This is crucial for constructing meaningful sentences as prepositions help delineate how nouns interact with their surroundings or with other concepts.

Understanding the role of prepositions is fundamental for grasping sentence structure and enhancing clarity in communication.
