How are prepositions used in sentences?

Prepositions are used in sentences to show the relationship between a noun or pronoun and another word in the sentence. They indicate location, direction, time, manner, and other relationships. Prepositions are typically followed by a noun or pronoun, which is called the object of the preposition. For example, in the sentence "She walked to the park," the preposition "to" shows the direction of the action (walking) and is followed by the noun "park."
