Comma Splice, Run-On sentences and how to fix them

 


Comma splice 

A comma splice occurs when a comma is incorrectly used to join two independent clauses. The words on either side of the comma could be two separate sentences.

How to fix comma splice:

1. use a full stop and create two sentences. 

Comma splice:

 I went swimming, I am feeling tired.
Corrected using a full stop: 

 I went swimming. I am feeling tired.

2. use a semi-colon to separate them.

Comma splice:

 I went swimming, I am feeling tired.

Corrected using a semi-colon: 

 I went swimming; I am feeling tired.

A semi-colon is used to resolve a comma splice when

i. the two independent clauses are related and

ii. there is a clear logical connection between the two independent clauses.

3. Use a coordinating conjunction. (FANBOYS – for, and, nor, but, or, yet, so)

A conjunction is used to combine the two independent clauses into a single sentence. Further, a conjunction indicates the logical relationship between the two clauses.

Comma splice:

I went swimming, I am feeling tired.

Corrected using a coordinating conjunction: 

I went swimming, and I am feeling tired.

4: Use a subordinating conjunction.

Similar to coordinating conjunctions subordinating conjunctions show the logical relationship between two independent clauses and solve the comma splice. However, subordinating conjunctions underline the unequal stress on the two parts of the sentence.

Comma splice:

 I went swimming, I am feeling tired.

Corrected using a subordinating conjunction: 

Since I went swimming, I am feeling tired.

(a few of the subordinating conjunction - although, after, before, unless, as, because, even though, if, since, until, when, while)

This is not how comma-splice is fixed

Two sentences must never be joined using a comma followed by a conjunctive adverb. Most commonly the conjunctive adverb however is used to join two sentences.

Example:

Comma splice: I went swimming, I am feeling tired.

Incorrect use of conjunctive adverb: I went swimming, however I am feeling tired.

Conjunctive adverbs are used to begin independent clauses, not to join them.  Hence the above correction of comma splice will not work as the sentence still is a comma splice.

Accordingly, additionally,  besides, certainly, comparatively, consequently, elsewhere, equally, finally, further, hence, however, in addition, in comparison, in contrast, incidentally,  likewise are a few conjunctive adverbs.

Note: A conjunctive adverb can be used to fix a comma splice BUT use a full stop or semi-colon before the second independent clause.

I went swimming. Now, I am feeling tired.

I went swimming; now, I am feeling tired.

 A run-on sentence 

A run-on sentence occurs when two independent sentences are squashed together without a conjunction or a proper punctuation mark.

Comma indicates a short pause whereas independent clauses are complete thoughts or complete sentences. They need a full stop to indicate a longer and stronger pause and don’t need a comma to separate them. If a comma is used, then it becomes a run-on sentence.

Example of run-on sentence -

I was happy, I sang for an hour.

In the above sentence, it is to be noted that the comma is used wrongly to separate two independent clauses.

Note: It is important to understand that length doesn’t determine a run-on sentence.

Molly Bloom's soliloquy in the James Joyce novel  Ulysses (1922) contains a sentence of 3,687 words.

How to fix run-on sentence:

Use one of the following 4 ways to correct a run-on sentence.

1. Separate the two clauses with a full-stop.

I was happy. I sang for an hour.

2. Separate the two clauses using a semi-colon.

I was happy; I sang for an hour.

3. Separate the two clauses using a comma with a coordinating conjunction. (FANBOYS – for, and, nor, but, or, yet, so)

I was happy, so I sang for an hour.

4. Separate the two clauses using a Subordinating conjunction and a comma.

(a few of the subordinating conjunction - although, after, before, unless, as, because, even though, if, since, until, when, while)

Since I was happy, I sang for an hour.

As is evident from this post FANBOYS - coordinating conjunctions  - are one of the heroes of English Grammar.
