Commas rules in English Language

The Comma is a small but powerful tool in writing. A misplaced comma can change the meaning of an entire sentence and it can cause confusion and misunderstanding. Commas add clarity and make your writing more effective. This article will explain the important rules of comma placement and ultimately you can improve your writing skills.

Understanding Basic Rules of Comma

Commas uses in list

Commas help separate items in a list. This include adjectives, nouns, and actions. The serial comma or oxford comma comes before the final “and” or “or”

Examples:

  • Oxford comma : I packed my bag with a toothbrush, shampoo, and a towel.(the oxford comma appears before the word “and”)
  • Without the oxford comma : I packed my bag with a toothbrush, shampoo and a towel. (the comma before “and” is omitted.)

The oxford comma is controversial and about 60% of editors prefer this because they believe it reduces ambiguity. Whether you use it or not may depend on your audience.

Commas with Coordinating Conjunctions

Coordinating conjunctions join independent clauses. The “FANBOYS” acronym helps you remember the conjunctions “for, and, not, but, or, yet, so.( FANBOYS)

Example: We wanted to go for a walk, but it started rain.

Commas before coordinating conjunctions are important when they connect two independent ideas.

Commas in Introductory Elements

Introductory phrases set up the foundation for a sentences. These elements are usually followed by a comma.
  • Introductory phrases : After lunch, we went for shopping
  • Introductory Clauses : I am happy to join you, although we were late
  • Introductory words : Yes, we are happy to join you.

These commas improves readability and make the main points clear.

Placement of Commas in Dependent and Independent Clauses.

 

It is important to understand the difference between dependent and independent clauses. An independent clause can stand on its own, but a dependent clause cannot stand on its own.

Example:

  • Independent : She likes Reading
  • Dependent : Because she likes reading

Commas are often needed when combining these sentences. Example: Because she loves reading, she spends a lot of her time in the library. 

Non-restrictive and Restrictive Clauses/Subordinate Clauses

Non-restrictive subordinate clauses add additional information but are not essential to the main clause. A comma is needed

  • Ex: My younger brother who lives in New York is coming to visit

The restrictive subordinate clause is necessary to understand the sentence. Do not include a comma

  • The book you lent me is interesting

To identify them, ask whether the meaning of the sentence changes without the subordinate clause

Comma Errors and Run -on  Sentences

Comma errors occur when two independent clauses are mistakenly connected with a comma. Example:

  • Incorrect: I love pizza, it’s my favorite food.
  • Correct: I love pizza, it’s my favorite food.

Run-on sentences occur when clauses are connected without punctuation. Example:

  • Incorrect: I went to the store but forgot my wallet.
  • Correct: I went to the store but forgot my wallet.

Understanding these errors will prevent confusion and make things easier to read
