How to Use Important Parts of Speech – Prepositions, Conjunctions, and Interjections
Let’s talk about the parts of speech that act like glue and fireworks.
Yes, you read that right. Prepositions and conjunctions? They’re your sentence glue—holding everything together so your thoughts don’t fall apart mid-conversation. And interjections? Well, those are your little explosions of emotion. Pow! Zap! Yay!
This post is your deep dive into how these essential (but often overlooked) words shape your English. Whether you’re writing an email, having a chat, or reading your favorite book, you’re using them constantly—probably without realizing it. Let’s change that.
Prepositions are words that show the relationship between a noun (or pronoun) and another part of the sentence. They often describe direction, time, place, or introduce an object.
The noun/pronoun that follows a preposition is called the object, and together they make a prepositional phrase.
Examples:
Each prepositional phrase helps clarify the picture: where, when, how, or why something happened.
There are over 150 prepositions in English—and no, you don’t need to memorize them all (unless your 7th-grade English teacher insists). But the more familiar you are with them, the smoother your English will become.

If prepositions are glue, conjunctions are the relationship experts of grammar. They link words, phrases, and clauses.
These connect elements of equal importance.
FANBOYS is your memory trick:
For, And, Nor, But, Or, Yet, So
Examples:
These connect a dependent clause to an independent one.
Examples:
These words create complex sentences—and complex sentences make your English sound polished.
These come in pairs.
Examples:
🧠 Try this practice tip:
Take a journal entry or email you’ve written. Circle every conjunction. Could you combine or expand any sentences using one of the three types above?
Interjections are emotional sound bites. They’re short words or phrases that show feeling or reaction.
Examples:
Sometimes they’re full sentences (“Yikes!”), and sometimes they’re sprinkled into longer ones:
These little expressions give your English personality. Learn them, use them, and your conversations will sound more human and natural.
