Definition of preposition

Prepositions are  word that indicates the relationship between a noun or pronoun and other words in a sentence.  The relationships include direction, place, time, cause, manner and amount.

Prepositions are abstract words that have no concrete meaning. They merely show the relationships between groups of words.

There are 2 major rules when it comes to the use of prepositions.

 1.       The first major rule deals with preposition choice. Certain prepositions must follow certain words, and the correct preposition must be used to make relationships between words in the sentences clear.

 2.       The second major rule deals with the prepositions place in the sentence. Prepositions must be followed by nouns, and prepositions can only go on the end of the sentence in certain situations.

For example:

• The stars shine at night.
• In England, it often snows in December.
• Her birthday is on 20 November.
