"Of" itself is a preposition, and is already used to create prepositional phrases.
Here's how you can use "of" to create prepositional phrases:
* "Of the city": This phrase tells us the location or origin of something.
* "Of great importance": This phrase describes the significance of something.
* "Of my friends": This phrase identifies a specific group of people.
To rephrase a sentence using a different preposition, you might need to change the meaning slightly or use a different structure altogether. For example:
Original Sentence: The book is *of* great interest.
Rephrased Sentence: The book is *very* interesting.
Let me know if you have a specific sentence in mind, and I can help you rephrase it using a different preposition.
