But suddenly, trying to explain it in simple words felt way harder than it should have been.<\/p>\n\n\n\n
We all use conjunctions daily (even without thinking). <\/p>\n\n\n\n
But when it comes time to explain them or use them correctly, <\/em>it suddenly feels like you hit a wall. <\/p>\n\n\n\n What do they really do? When do you need a comma? <\/p>\n\n\n\n Why do some sentences sound wrong, even when they\u2019re technically right?<\/p>\n\n\n\n This blog breaks it all down.<\/p>\n\n\n\n Key Takeaways<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n Explaining what are conjunctions isn\u2019t as easy as describing a noun<\/a>, but let me try to do a better job here than I did trying to explain it to my cousin.<\/p>\n\n\n\n A conjunction is a word that connects. <\/p>\n\n\n\n That\u2019s it. It links words, phrases, or whole sentences together so your writing does not feel awkward or choppy.<\/p>\n\n\n\n Here\u2019s a quick example:<\/p>\n\n\n\n See the difference? It\u2019s barely noticeable, but adding one tiny word changed the whole rhythm of the sentence. <\/p>\n\n\n\n It helped show the relationship between the two ideas.<\/p>\n\n\n\n You\u2019d think all conjunctions do the same job, but that\u2019s not the truth.<\/p>\n\n\n\n Some connect equal words, while others connect ideas that depend on each other. <\/p>\n\n\n\n A few of them, on the other hand, work in pairs.<\/p>\n\n\n\n The following breakdown will help you make sense of it:<\/p>\n\n\n\n These are the most common ones and the easiest to use. Coordinating conjunctions connect words, phrases, or independent clauses that are grammatically equal.<\/p>\n\n\n\n Think peanut butter and<\/strong> jelly. They go side by side, don\u2019t they?<\/p>\n\n\n\n There are only seven of them, and you can remember them with the acronym FANBOYS<\/strong>:<\/p>\n\n\n\n Example:<\/strong><\/p>\n\n\n\n Subordinating conjunctions connect two ideas, but one depends on the other. <\/p>\n\n\n\n They usually introduce a dependent clause (an incomplete thought) and attach it to an independent clause (a complete sentence).<\/p>\n\n\n\n Complicated, huh? Not really.<\/p>\n\n\n\n In simple words, they show cause, time, condition, contrast, or reason. They answer questions like Why? When? Under what condition?<\/em><\/p>\n\n\n\n Common subordinating conjunctions include:<\/p>\n\n\n\n If you\u2019ve ever asked yourself what are the subordinating conjunctions, now you know! <\/p>\n\n\n\n They\u2019re the glue that connects ideas when one thought relies on the other to make sense.<\/p>\n\n\n\n These work in pairs. You use correlative conjunctions when you want to link balanced ideas in a sentence.<\/p>\n\n\n\n Examples include:<\/strong><\/p>\n\n\n\n Example:<\/strong><\/p>\n\n\n\n They add a nice rhythm to your writing when used right. But there\u2019s a small catch to it. <\/p>\n\n\n\n If you don\u2019t keep the structure balanced on both sides, they lose their charm.<\/p>\n\n\n\n Now I don\u2019t expect you to get the hang of it instantly, especially if you\u2019re a student. <\/p>\n\n\n\n Lucky for you, I have something that might help.<\/p>\n\n\n\n For instance, you could ask it to explain what are subordinating conjunctions and how to use them. It will provide you with a detailed explanation of the topic.<\/p>\n\n\n\n Conjunctions often just slip into our sentences. <\/p>\n\n\n\n More often than not, we don\u2019t even realize they are the culprit behind our sentences feeling a little off.<\/p>\n\n\n\n But that stops now. The next time you start writing, make sure you remember these rules:<\/p>\n\n\n\n If you\u2019re joining two complete sentences<\/strong> (also called independent clauses) with a coordinating conjunction \u201clike and<\/em>, but<\/em>, or so<\/em>,\u201d you usually need a comma before the conjunction<\/strong>.<\/p>\n\n\n\n Correct:<\/strong> I wanted to go to the beach, but<\/strong> it started raining. However, if you\u2019re only joining two words or short phrases, no comma is needed.<\/p>\n\n\n\n Trying to link too many ideas together with conjunctions can make your sentence confusing or messy.<\/p>\n\n\n\n Example:<\/strong> I wanted to go for a walk and<\/strong> I was tired but<\/strong> I needed air so<\/strong> I still went and<\/strong> then I saw my friend.<\/p>\n\n\n\n Notice how messy that sounds? When you\u2019ve more to say, you should break long sentences into shorter ones. Let me demonstrate what a better version of the complex sentence<\/a> above would look like.<\/p>\n\n\n\n I was tired, <\/em>but<\/em><\/strong> I needed air. So, I went for a walk and ran into a friend.<\/em><\/p>\n\n\n\n When using correlative conjunctions like either\u2026or<\/em> or not only\u2026but also<\/em>, both parts of the sentence should follow the same grammatical structure.<\/p>\n\n\n\n The sentence, \u2018She is <\/em>not only<\/em><\/strong> smart but also works hard,\u2019 <\/em>feels a bit awkward. Why? Because you\u2019ve got to match nouns with nouns, verbs with verbs, and so on.<\/p>\n\n\n\n The correct version would read: She is not only<\/strong> smart but also<\/strong> hardworking.<\/p>\n\n\n\n A subordinating conjunction (because<\/em>, although<\/em>, since<\/em>, if<\/em>) makes a sentence dependent. This means the sentence can\u2019t stand alone.<\/p>\n\n\n\n Wrong:<\/strong> Because I was tired. (This is incomplete)<\/em> It doesn\u2019t matter if you place the dependent clause at the beginning or the end as long as your full sentence is complete.<\/p>\n\n\n\n Sometimes we accidentally stack conjunctions out of habit, especially when we\u2019re speaking informally. In writing, it can make your sentence clunky.<\/p>\n\n\n\n Example:<\/strong> Although she was tired, but she still went out.<\/p>\n\n\n\n Correct: <\/strong>She was tired, but<\/strong> she still went out. <\/p>\n\n\n\n Each conjunction has a particular purpose. Always pick the one that clearly shows what you mean.<\/p>\n\n\n\n Now, all these rules will not come naturally to you. It will take time and practice. Meanwhile, you can use Undetectable AI\u2019s Grammar Checker to fix any conjunction mistakes in your writing.<\/p>\n\n\n Okay, so you get the idea of what conjunctions are. Now, let\u2019s see how they are actually used in sentences.<\/p>\n\n\n\n Conjunctions are not as much of a headache as long as you don\u2019t make the following mistakes:<\/p>\n\n\n\n You can absolutely start your sentence with a conjunction. It\u2019s not a crime. <\/p>\n\n\n\n If starting with a conjunction makes your sentence more natural or dramatic, go for it. Just don\u2019t overdo it.<\/p>\n\n\n\n When you start a sentence with a subordinating conjunction but do not finish the thought, you mess up. It leaves the reader hanging.<\/p>\n\n\n\n The sentence, <\/strong>\u2018Although it was raining,\u2019 feels incomplete. But \u2018Although it was raining, we still went hiking<\/em>\u2019 feels complete.<\/p>\n\n\n\n Using one half of the pair but not the other, or creating a mismatched structure, is another common mistake.<\/p>\n\n\n\n Always use the full pair (not only\u2026but also, either\u2026or, neither\u2026nor) and keep both sides balanced.<\/p>\n\n\n\n Never put 4 or 5 ideas into a sentence just because conjunctions can<\/em> connect things. Break it up. Use conjunctions to guide the reader. Do not use them to overwhelm the readers.<\/p>\n\n\n\n Personally, I always turn to the AI Humanizer<\/a> by Undetectable AI when I can\u2019t figure out the correct usage of conjunctions.<\/p>\n\n\n No, this tool isn\u2019t only for bypassing AI-content detection<\/a>. <\/p>\n\n\n\n It can even rephrase human-written content to make it sound more natural, flow better, and have a proper structure.<\/p>\n\n\n\n One of the most effective ways to avoid mixing up your conjunctions is to compress the rules into a single, catchy word that sticks in your mind.<\/p>\n\n\n\n By using Undetectable AI’s Acronym Generator to help you create mnemonics that make memorizing lists of conjunctions much easier, you can build your own custom study hacks that stay with you long after you\u2019ve finished your homework.<\/p>\n\n\n\n Truth be told, most of the time, your intuition already knows which conjunction fits. <\/p>\n\n\n\n The trick is asking yourself one question:<\/p>\n\n\n\n \u201cWhat am I trying to connect here?\u201d<\/strong><\/p>\n\n\n\n You don\u2019t need to memorize a hundred rules. All you need to do is listen to your sentence. If it feels off, the conjunction might be wrong (or maybe you don\u2019t need one at all).<\/p>\n\n\n\n Understanding what are coordinating conjunctions or subordinating conjunctions is one thing. But being able to use them confidently is another.<\/p>\n\n\n\n These quick exercises will test your understanding:<\/p>\n\n\n\n Choose the correct conjunction to complete each sentence:<\/p>\n\n\n\n Combine these short sentences using appropriate conjunctions:<\/p>\n\n\n\n You can also check out these printable worksheets<\/a> to further put your knowledge to test.<\/p>\n\n\n\n Start optimizing your content\u2014use our AI Detector and Humanizer below.<\/p>\n\n\n\n
