Prepositions are words which link nouns, pronouns and phrases to other words in a sentence
Prepositions may sometimes be used to end sentences. For example, "What did you put that there for?" (better English is the alternative: "Why did you put that there?") Example 2: "A pen is a device to write with" (better English is "A pen is a writing device"). In general, because they are links, prepositions belong in the middle of sentences, rather than at the end.
The table below shows some examples of how prepositions are used in sentences.
|Position||The cat is under the table.|
He is sitting on the chair.
|Time||The class starts at 8 am.|
I am going to Spain on Wednesday.
|How something is done||We travelled by car.|
|Possession||The book belongs to Colin.|
The door of the house is red.
