1. What Is a Preposition? Definition and Examples
A preposition is a word that connects a noun, pronoun, or noun phrase to other words in a sentence. It indicates the relationship between the noun or pronoun and other elements of the sentence, often expressing location, direction, time, or manner. Think of prepositions as the glue that holds sentences together, providing context and clarity.
-
Definition: A preposition is a word governing, and usually preceding, a noun or pronoun and expressing a relation to another word or element in the clause.
-
Key Function: To show the relationship between a noun or pronoun (the object of the preposition) and another word in the sentence.
-
Examples:

- She went to the store. (direction)
- We will meet at 3 PM. (time)
- He did it with a smile. (manner)

- Context: They provide essential context, helping to specify location, time, direction, and more.
- Avoid Ambiguity: They prevent misinterpretations by clearly defining the relationships between different parts of a sentence.
