Does a prepositional phrase come befroe or after noun?

Prepositional phrases can come before or after a noun, depending on the sentence structure and what you want to emphasize.

Here are some examples:

Before the noun:

* On the table, the book lay open. (Emphasis on the location of the book)

* With a smile on her face, she greeted him. (Emphasis on her expression)

After the noun:

* The book on the table was open. (Emphasis on the book itself)

* She greeted him with a smile on her face. (Emphasis on the action of greeting)

Important Note:

* A prepositional phrase usually modifies a noun or pronoun, giving us more information about it.

* Prepositional phrases are groups of words that start with a preposition (like "on," "with," "in," "at") and include an object (a noun or pronoun).
