What are Prepositions?
Prepositions are components of a sentence that talk about the position of the subject or object in a sentence. They indicate the position of anything by comparing its placement or location with respect to its surroundings. For example, if we say that 'the book is on the table.' We are referring to its position with respect to the table that is present in its surroundings. Being on the table tells the reader that the book is kept on the table. Here we cannot use a preposition 'above,' which is somehow similar to 'on.' 'Above' is used if an object hovers above anything and is not in contact with another object.
