A preposition is used to link a noun or a pronoun in a sentence to another element in it. "Pre position" means place before; no wonder prepositions are placed before a noun or pronoun most of the time.
Kevin is eating at the restaurant.
Bob and Martha are with him.
Quick tip: A preposition must have an object; in some cases, the object may not be placed right after the preposition.
I bought it at the store.
Who did you talk to? (The object of preposition is not right after the preposition; it comes at the beginning of the sentence: talked to whom.)

Based on how many words are in it, a preposition can be simple, double, or compound.
These are one-word prepositions. Examples of simple prepositions are at, in, on, etc. This type is the most common type of prepositions.
Who is at the door?
I'm in a meeting.
The cat is hiding under the table.
These prepositions have two words put together to form one preposition. Examples of double prepositions are into, up to, out of, etc. We find this type of prepositions quite a lot.
It is now up to you to decide.
Little Sara will turn into a lady one day.
This type of prepositions contains two or more words. Compound prepositions are mostly used in formal English. Examples are in addition to, on behalf of, etc.
In addition to a bike, Mike has a car.
Aside from baseball, I hardly watch any television.
Based on their function, prepositions can be divided into three categories: prepositions of time, prepositions of place, and prepositions of direction.
Prepositions of Time
A preposition of time is a preposition that indicates a specific time.
Can you finish the assignment before dinner?
Dad landed in New York at 9 am.
Prepositions of Place
A preposition of place is a preposition that indicates a specific place.
Mom works in New York.
Jason is sitting on the chair.
Prepositions of Direction
A preposition of direction is a preposition that indicates a specific direction.
The bus is going toward the city center.
Ralph is walking down the street.
Useful tip: Not every preposition can be categorized under one of the three types: time, place, or direction.
despite, without, etc.
Quick tip: Using different prepositions in the same sentence can change the meaning.
Look at the two sentences:
Alex works for Max Solutions.
Alex works with Max Solutions.
The first sentence means Alex is employed by Max, and the second one means he works in association with them on equal footing, and not necessarily employed by them.
Students face a bit of a struggle dealing with words that can function as both prepositions and conjunctions. Examples of such words include since, before, until, etc. The point here is if the word is followed by a clause, it's a conjunction. If what we have is a noun phrase and not a clause, it's a preposition.
After the meeting was over, I went to the gym. (conjunction, clause)
After the hours-long meeting, I went to the gym. (preposition, noun phrase)
There are certain words that can be both prepositions and adverbs. The watchword is if there is an object after the word, it's a preposition. If not, it's an adverb.
I am waiting outside the building. (preposition, object of preposition)
I am waiting outside. (adverb, no object of preposition)

Many people believed, and many still believe that a sentence can't end with a preposition; they base their argument on the rule that a preposition is always followed by a noun or pronoun. This, however, is not true.
Look at the sentences:
This is something I'm interested in it. (incorrect)
This is something I'm interested in. (correct)
The first sentence sounds unnatural and therefore is not correct.
Useful tip: Different from Vs different than
