Sentence structure matters, no matter who you are.
You might be a student trying to get a passing grade on anย essay, a guy trying toย text to a smart girl without humiliating yourself, an employee writing a company-wide memo, or a writer working on your next book. When sentence structure gets out of whack, there can beย consequences (no passing grade, no first date, no raise, no publishing contract, no bueno).

Bad Sentence Structure Makes for Weird Sounding Sentences
When you write, you useย a different part of the brain than when you speak. That’s why writing can beย so hard for many of us, myself included. You might communicate perfectly when you talk, but when you write, you stareย at the screen for fifteen minutes trying to figure out what to say.
Many people especially struggle with sentence structure. Most of usย are taught sentence structure in the third and fourth grade, but we usually forget it just as quickly.
Who really needs to know what a subject and predicate is or why you shouldn’t useย comma splices?
Who needs to know?ย You do! That is, ifย you don’t wantย to your writing to sound ridiculous. Ifย you don’t structure your sentences correctly, your writingย will sound strange, like there’s something “off” about it. This might not matter in a textย message to your friends, but it could definitely matter when you’re writing that essay for English class or sendingย an important email for work.
Here’s the point: Smart people use correct sentence structure. (Tweet that?)
Sentence Structure Basics: Subject and Predicate
To begin, let’s talk about the basics of sentence structure. If you’re serious about sentence structure, you probably already know what a subject and predicate is. For everyone else, here are theย simple definitions:
Subject.ย Theย subjectย is what theย sentence is about. For example:ย John drove his car off the bridge. Is John crazy?
Predicate. Theย predicate is whatย the subject is up to. In other words, theย predicate “completes an idea about the subject,” according to Wikipedia. For example:ย John got out of the ruined car, andย he laughed uproariously.ย A subject almost always includes a noun (there are some exceptions), but a predicate must include a verb.
Sometimes, a subject isn’t included in the sentence but just implied. For example,ย Don’tย drive off bridges!ย Here, there is no subject, but it’s implied by the context.
Forย more complex explanations, use the following links (subject, predicate).
The 4 Types of Sentences
When you put a subject and a predicate together, you getย a clause! (Yes, like Santa.) The fun thing is you can combine clauses together to form different types of sentences.
Good writers vary the types ofย sentences they use. For example, don’t useย too many simple sentences. You might sound childish. However, if you use too many compound-complex sentences, your writing might be too difficult to understand.
Here are the four types of sentences:
Simple Sentences
Simple sentences contain a single clause (i.e. one subject, one predicate). Here are a few examples:
- John had broken his toe.
- Johnย shouted in pain.
- John was very stupid.
Compound Sentences
Compound sentences contain two independent clauses (independent because they could be their own sentences) which are joined together with a coordinating conjunction (i.e. and, but, or, so). Here are a few examples:
- I didn’t know why John drove off the bridge, but Mark did.
- I asked him why, but heย wouldn’t tell me.
- I stopped asking, but I stillย wondered.
Complex Sentences
Complex sentences contain one independent clause and one or more dependent clauses (dependent because they couldn’t be their own sentence) which are joined together by a subordinating conjunction (e.g. that, because, if, etc.*)
- Everything changed when John drove off the bridge.
- Whenever I drove across that bridge, I would think about driving off,ย too.
- Even though I would never do it, I thought about it all the time.
*Here’s a full list of subordinating conjunctions.
Compound-Complex Sentences
Compound-complex sentences contain at least two independent clauses and one dependent clauses. Here’s a long compound-complexย example:
Sometimes, when I drove over the bridge, my hand would start to turn the steering wheel toward the edge, but I would quickly stop myself because even Iย didn’t want to die.
When Sentence Structure Goes Wrong
You’ve seenย how sentences areย supposed to look, but what happens when sentences go wrong?ย And how can you avoid sounding like an idiot by structuring a sentence incorrectly? Here are four common ways sentence structure goes wrong:
1. Comma Splices
What if you decided to take two sentences and join them with a comma instead of a period? (Or, for the grammarphiles, what if you joined two independent clauses with a comma but left out the subordinating conjunction?)
Well, youย would have a comma splice, andย comma splicesย are bad.
Here’s an example of a comma splice:
John brokeย his toe, he shouted in pain.
See what I mean?ย Don’t do that.
Instead, just put in a conjunction (and, but, or, so) or replace the comma with a period.
John broke his toe, and he shouted in pain.
OR
John broke his toe. He shouted in pain
Isn’t that better?
2. Fragments
A fragment is anย incomplete sentence. Itย might have a subject. Itย might have a predicate. Itย neverย has both.
Here are a fewย examples:
- John broke his toe. And shouted in pain.ย (noย subject)
- Everything changed. When John drove off the bridge.
Fragments are against the rules, but in certain situations, they can be used effectively as a stylistic choice. However, unless you know what you’re doing, it’s a good idea to avoid them.
3. Run-on sentences
A run-on sentence is kind of like a comma splice except you take out the comma. Here’s what I mean:
John brokeย his toe he shouted in pain.
Run-on sentences are bad. Put a period in between those clauses!
Why You Should Care About Sentence Structure?
You probably aren’t going to diagram every sentence from now on. However, by becoming familiar with correct sentence structure,ย you willย become a betterย writer, and becoming a better writerย could help you pass your next class, get a job, and avoid humiliation on Facebook. It sounds like a good choice to me!
PRACTICE
Write a story about a guy who drove off a bridge. In your story, use at least one example of each of the four types of sentences we talked about above. Avoid the sentence-structure pitfalls.
Write for fifteen minutes. When you finish, post your practice in the comments section. And if you post, be sure to leave feedback for your fellow writers.
Have fun!
