Prepositions

• Prepositions indicate relationships between other words in a sentence.
• Many prepositions tell you where something is or when something happened.
• Most prepositions have several definitions, so the meaning changes quite a bit in different contexts.
• Ending a sentence with a preposition is not a grammatical error.

Examples:

I should rewrite the conclusion of my essay.

Sam left his sweater in the car.

Did you send that letter to your father?

Jack ate dinner with his mom.
