What is the difference between a conjunction and a preposition?

Hint: In the development of sentences, prepositions and conjunctions are extremely significant. There are significant variations between these two in terms of grammar. The above question is taken from grammar, parts of speech.

Complete answer:
A conjunction is a term that is used to link clauses or sentences together, as well as to coordinate terms within the same clause. The position of something is typically defined by a preposition. The purpose of a conjunction is to join words, phrases, clauses, or sentences together. Conjunctions are invariable grammar particles that may or may not stand between the objects they bind.
Some conjunctions are: and, as, because, but, for, just as, or, neither, either, nor, not only, so, whether.
Examples of conjunction are:
- I have two apples and a mango.
- Sita and Gita are sisters.

A preposition is a term that links nouns, pronouns, or phrases in a sentence to other terms. Prepositions are usually short words that are put immediately in front of nouns. Prepositions can be found in the front of gerund verbs in some situations.
Examples of preposition are:
- I always read books in the library.
- He climbed up the tree for mangoes.

Note: A conjunction joins two words, clauses, or phrases. Preposition specifies the position of something, the moment that something occurs, and the manner in which something is accomplished.
