Punctuation, Conjunction

1

In what conditions a comma should be used before a conjunction?

 

I read somewhere that in compound sentences, when a dependent and an independent clause are connected it would be proper to use a comma before a conjunction. Is it true?

Please read it so:

I regret the inconvenience caused!

Rahul,

 

I think Lewis's answer may have confused everyone.  You asked about an independent clause attached to a dependent clause. That is not a compound sentence and no comma is required with the conjunction.

 

Lewis responded with examples of two independent clauses. As Lewis demonstrates, to join two independent clauses, a comma + conjunction is required.  

 

Sorry to jump in, but a casual reader may be confused by the "subject disagreement" between question and answer.

I'm sorry to confuse you.A dependent clause + An independent clause = Complex.I asked about compound = independent clause + independent clause

Would this be correct:

The boy threw the ball: The dog chased after it.

 

(full colon, Capitalized first word of following independent clause)?

 

I think yes, but I defer to the experts.

No, colons are not used to link independent clauses. Colons are used before a list. Semicolons (;) may be used in place of a comma + conjunction.

Glad I learned before I used it!

In fact, the comma is not always needed when two independent clauses are joined by "and" -- this only applies to "and," not to other conjuctions.

 

The reason a comma is required (you MUST use a comma) in this sentence is to prevent possible misreading. 

 

"The boy threw the ball and the dog" . . . huh! . . . oh, and the dog "chased after it."
