Prepositions are words that link nouns, pronouns, and phrases to other words in a sentence. The word or phrase that the preposition introduces is called the object of the preposition. A preposition is simply a short word (like in, at, to) commonly placed before a noun (sometimes also before gerund verbs). Learning prepositions can pose a problem as there are no set rules to follow. Besides, an exact translation is usually not possible. A single preposition in a native language may have many translations depending on the situation. The best way to learn prepositions is to note them carefully while looking up a dictionary for word meanings. In addition, extensive reading and an alert mind can be a great help.

Example: The book is on the table.

A prepositional phrase is made up of the preposition, its object, and any associated adjectives or adverbs. A prepositional phrase can function as a noun, an adjective, or an adverb.
