* Phrases are groups of words that act as a single unit. They don't have a subject-verb structure.
* Prepositional phrases are a type of phrase that starts with a preposition and ends with a noun or pronoun (the object of the preposition).
Examples:
* "The cat sat on the mat"
* "The cat sat" is a verb phrase.
* "on the mat" is a prepositional phrase.
* "Running through the park, the dog chased its tail"
* "Running through the park" is a participial phrase (a type of phrase).
* "through the park" is a prepositional phrase.
Here are some other examples of sentences with phrases and prepositional phrases:
* "With a smile on her face, she walked down the street."
* "After a long day, she settled into her favorite chair."
* "Despite the heavy rain, the children played outside."
Important note: It's common to see multiple prepositional phrases within a sentence. The key is to understand how phrases function as units within the sentence, and how prepositional phrases act as modifiers, often describing the location, time, or manner of something.
