Prepositions are words that show the relationship between a noun or pronoun and other words in a sentence. They often indicate location, direction, time, or spatial relationships.
Examples of prepositions include: in, on, at, by, for, with, to, from, between, among, etc.
Conjunctions are words that connect words, phrases, or clauses in a sentence. They can be used to join similar elements or to show the relationship between different parts of a sentence.
There are three types of conjunctions: coordinating conjunctions (and, but, or, so, yet, for, nor), subordinating conjunctions (after, although, because, if, since, when, while), and correlative conjunctions (either...or, neither...nor, both...and, not only...but also).
Interjections are words or phrases used to express strong emotions or sudden feelings. They are often followed by an exclamation mark and can stand alone as a complete sentence.
Examples of interjections include: wow, oh, ouch, hey, yikes, bravo, etc.
