can there be a prepositin in the subject

The complete subject can contain a preposition.

Example:

Some of my friends are going to the concert.

A prepostion is like a place. Behind, above, under, over, right, left.

no duhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

In English grammar, a preposition is typically used to show the relationship between a noun or pronoun (the object of the preposition) and another word in the sentence. Prepositions are usually used to indicate location, direction, time, manner, or cause.

The subject of a sentence is the noun, pronoun, or noun phrase that performs the action or is the focus of the sentence. It generally answers the question "who" or "what" the sentence is about.

Typically, prepositions are not found directly in the subject of a sentence. The subject itself is usually a noun or pronoun without any prepositional phrases attached to it.

However, there are certain constructions where a preposition can be found within the subject. This usually occurs when the subject consists of a noun phrase modified by a prepositional phrase.

For example:
- "The man on the corner is my friend." Here, the subject "the man on the corner" contains the preposition "on" within the noun phrase "man on the corner."

It's important to note that even though the preposition is within the subject, it still does not function as part of the subject. The subject itself remains the noun or pronoun at the core of the subject phrase.

So while it is less common, there are instances where a preposition can be found within the subject of a sentence.
