Prepositions are words used to show relationships between other words in a sentence. They typically indicate direction, place, time, cause, manner, or possession. Prepositions are always part of a prepositional phrase, which includes the preposition and its object (a noun, pronoun, or noun phrase).
Types of Prepositions:
1. Prepositions of Place/Location:
Indicate the location of something.
Examples: at, in, on, under, between, near
Sentence: The book is on the table.
2. Prepositions of Direction/Movement:
Indicate movement from one place to another.
Examples: to, into, onto, through, towards
Sentence: She went to the store.
3. Prepositions of Time:
Show when something happens.

4. Prepositions of Manner, Cause, or Instrument:
Show the manner, reason, or means of an action.
Examples: by, with, about, of, because of

5. Prepositions of Possession:
Indicate possession or connection.

Key Rules for Prepositions:
A preposition is always followed by its object (noun or pronoun).

Do not end a sentence with a preposition in formal writing.

Prepositions can change meaning based on context.
Example: "He is in the room" (inside) vs. "He is on the committee" (part of a group).
