What is the aims and objectives of preposition?

Answer 1

In languages such as English, that prepositions, they tend to come before nouns and pronouns to describe position, direction of movement, etc.

For example:

I am *on* the train

I looked *at* him

Prepositions are often teamed up with a verb in a partnership known as a "phrasal verb". In this partnership, the verb can completely change its original meaning.

For example:

Look into: means 'examine', whereas the plain meaning would be to look inside something (eg. a box)

Look up: as a phrasal verb, can mean 'research a topic in a reference source'; whereas the plain meaning would be look in an upwardly direction.

Look up to: as a phrasal verb, means 'respect'

Look to: as a phrasal verb can mean 'rely on'

Answer 2

The aim of prepositions is to show the relationship between a noun or pronoun and other elements in a sentence. They help provide context and clarify the position or direction of things in relation to one another. Objectives include indicating location, time, direction, and relationships between nouns.
