Prepositions

A preposition is a word placed before a noun or a pronoun to show in what relation the person or thing denoted by it stands in regard to something else. The word 'preposition' literally means 'placed before'. The noun or pronoun which follows a preposition is called its object, and it is always in the objective case.

Prepositions are classified based on their meaning and context. Prepositions of place (such as in, on, at, under) indicate where an entity is located. Prepositions of time (such as on, in, at, during, since) indicate when an event occurs. Prepositions of direction or motion (such as to, into, toward, through) show movement. There are also compound prepositions (according to, because of) and participial prepositions (concerning, regarding).

According to CBSE board grammar tests and the Cambridge curriculum, one of the most challenging aspects of English is learning appropriate prepositions. Prepositions must be used in specific collocations (fixed expressions). For instance, one is 'interested in' something, 'good at' an activity, and 'accused of' a crime. Developing an intuitive understanding of these relationships through reading and practice is essential for producing natural-sounding English.
