Why Do We Even Need Subordinating Conjunctions?
Ever notice how a sentence like "I went to the store and I bought milk" feels flat, almost like it's missing something? So naturally, " That little word "because" changes everything. Now try: "I went to the store because I needed milk.It adds reason, context, depth.
Subordinating conjunctions are those quiet workhorses of grammar that let us connect ideas smoothly, showing relationships between clauses instead of just stringing statements together. Plus, they're the difference between choppy writing and flowing prose. Between simple sentences and sophisticated ones.
But here's what most people don't realize: there aren't that many of them. Probably fewer than you think. And once you know them, you'll start spotting them everywhere.
What Are Subordinating Conjunctions?
Let's get specific. In practice, these aren't coordinating words like "and," "but," or "or. In practice, " Those just connect equals. A subordinating conjunction is a word that joins a dependent clause to an independent clause, showing that one clause can't stand alone. Subordinating conjunctions create a hierarchy—one part depends on the other.
Take this sentence: "Although it was raining, we went hiking.That said, " The clause "although it was raining" can't exist on its own as a complete thought. Which means it needs the main clause "we went hiking" to give it meaning. That's the hallmark of a dependent clause, introduced by a subordinating conjunction.
The most common ones fall into categories based on what kind of relationship they show:
Time-Based Subordinating Conjunctions
These tell us when something happens. You know many of these already.
When, while, before, after, since, until, as soon as, once, whenever
"Since I moved to the city, I've been exhausted."
"While I was cooking dinner, my phone rang."
These words introduce time clauses that depend on the main action. Without them, you've got fragments.
Cause and Reason Conjunctions
These explain why something happens. They're the backbone of logical argumentation.
Because, since, as, because of, now that, given that, in order that
"I couldn't sleep because of the noise."
"Since you're here, we can start the meeting."
Notice how "because" and "since" appear in both time and cause categories? Context matters more than the word itself.
Contrast and Comparison Words
These show opposition or similarity between ideas.
Although, though, even though, whereas, while, instead of, rather than, on the contrary
"Although she studied hard, she didn't pass the exam."
"While I prefer coffee, I'll take tea today."
"Even though it's expensive, I bought it anyway."
Condition and Concession Words
These introduce hypothetical or uncertain situations.
If, unless, provided that, except if, in case, whether...or
"If it rains tomorrow, we'll cancel the picnic."
"Unless you hurry, we'll miss the train."
Purpose and Result Words
These explain intention or consequence.
So that, in order that, so...that, such that
"She saved money so that she could travel."
"He spoke so quietly that no one noticed."
Place and Manner Words
Less common but still important for specific contexts.
Where, wherever, wherever it is, just as, as if, as though
"Do it where it's convenient for you."
"She moved through the crowd as if she weren't there."
The Complete List (Finally!)
Here's the comprehensive rundown of subordinating conjunctions you'll encounter:
Adversative (showing contrast): although, though, even though, whereas, while, instead of, rather than
Causal (showing reason): because, because of, since, as, now that, given that, in order that
Comparative (showing similarity): like, as if, as though, just as, similar to
Conditional (showing conditions): if, unless, provided that, except if, in case, whether...or
Temporal (showing time): when, while, before, after, since, until, as soon as, once, whenever, where, wherever
Purpose (showing intention): so that, in order that, for the purpose of
Result (showing consequence): so...that, such that
Place (showing location): where, wherever
Manner (showing way): as, as if, as though, just as
That's it. Maybe forty words total. Memorize them, and you'll recognize their function in any sentence.
Why People Get Confused
Honestly, this is where most grammar guides lose me. Think about it: they make subordinating conjunctions sound complicated. But really, you use most of these naturally every day.
The confusion usually comes from mixing them up with coordinating conjunctions. In real terms, remember: FANBOYS are for equals (for, and, nor, but, or, yet, so). Subordinating conjunctions create unequal relationships.
Another mix-up happens with transitional words. "Even so," "therefore," "therefore" — these aren't subordinating conjunctions. They're transitional adverbs that show relationship between ideas but don't join clauses the same way.

And here's what most people miss: some words can function as different types of conjunctions depending on context. "Since" can mean time ("Since Monday") or reason ("Since you asked"). The meaning changes with usage, not the word itself.
Common Mistakes People Make
Let's be real about where this trips people up.
Overcomplicating simple ideas. You don't need "inasmuch as" when "because" works fine. Most writing benefits from clarity, not complexity.
Using subordinating conjunctions incorrectly. "Although I was tired, therefore I went to bed" — that's wrong. "Therefore" doesn't belong in a dependent clause. Choose the right tool for the job.
Creating comma splices. When you join two independent clauses with a subordinating conjunction, you need a comma before the dependent clause. "I was hungry, so I ate." But "I was hungry so I ate" is also acceptable in casual writing, though not formal.
Misplacing the conjunction. "Because I was cold I went inside" loses the connection between clauses. Add that comma: "Because I was cold, I went inside."
Practical Applications
So what? Why does this matter for your writing?
In emails and professional communication. "Since the deadline has passed, we need to revise our approach." Shows cause and effect clearly.
In storytelling. "Although the storm raged outside, the children played happily inside." Creates atmosphere and contrast.
In academic writing. "Given that research shows correlation, we cannot assume causation." Demonstrates logical reasoning.
In everyday conversation. We do this naturally: "I can't go out because I have work." But recognizing it helps us communicate more precisely.
Quick Recognition Tips
Here's how to spot a subordinating conjunction in action:
-
Look for the dependent clause first. If it starts a sentence and can't stand alone, you've got a subordinating conjunction introducing it.
-
Check if removing the clause breaks the sentence. "Because it was raining" removed makes "We went hiking" complete. The first part was dependent.
-
Notice the comma placement. Usually, there's a comma after the dependent clause when it comes first.
-
Identify the relationship. What does this clause show? Time? Reason? Contrast? That'll help you identify which conjunction it is.
Practice Makes Perfect
Try this exercise: take simple sentences and connect them with appropriate subordinating conjunctions.
"I was tired." + "I went to bed early."
"I went to bed early because I was tired."
See how that works? The second sentence gives you more information, more context, more sophistication.
Frequently Asked Questions
Are there more subordinating conjunctions I'm missing?
Probably not many. Worth adding: the core list covers 95% of what you'll encounter. Some specialized texts use rarer forms, but for everyday writing, the main groupings serve you well.
Can I use multiple subordinating conjunctions in one sentence?
Absolutely. "Although it was raining, and since we'd planned the trip for months, we decided to
Can I use multiple subordinating conjunctions in one sentence?
Absolutely. "Although it was raining, and since we'd planned the trip for months, we decided to go hiking anyway." On the flip side, be careful not to overload your sentence. Because of that, multiple dependent clauses can make writing dense and hard to follow. Consider breaking complex thoughts into shorter sentences when clarity suffers.
What's the difference between a subordinating conjunction and a transitional word?
Transitional words like "however," "therefore," or "meanwhile" connect ideas between sentences or paragraphs but don't create grammatical dependencies. Also, subordinating conjunctions actually bind clauses together structurally. "However" might follow a period or semicolon, but "because" or "although" typically requires a comma when introducing a dependent clause.
Do I always need a comma with subordinating conjunctions?
Not always. "I went inside because I was cold" needs no comma, but "Because I was cold, I went inside" does. Because of that, when the dependent clause comes after the independent clause, the comma is usually unnecessary. The key is whether the dependent clause leads or follows.
How can I improve my instinct for proper usage?
Read actively. Pay attention to comma placement and clause structure in articles, books, and well-crafted emails. Notice how skilled writers deploy these conjunctions naturally. Over time, these patterns become second nature.
The Bottom Line
Subordinating conjunctions aren't just grammar rules to memorize—they're tools that give your writing precision and nuance. Here's the thing — they help you show relationships between ideas rather than simply listing facts. Whether you're crafting a business proposal, telling a story, or explaining why you can't meet for lunch, these little words carry significant weight.
Mastering them won't transform your writing overnight, but it will gradually make your communication clearer and more effective. Start by recognizing them in the text you read, then experiment with using them in your own writing. Soon, you'll find that these conjunctions become natural bridges between your thoughts and your reader's understanding.
Remember: good grammar isn't about following rigid rules—it's about communicating effectively. Subordinating conjunctions are among your most valuable tools for achieving that goal.
