Commas Colons and Semicolons

A comma splice occurs when two independent clauses are separated by a comma. This is incorrect punctuation.

Example: Someone is at the door, I need to get dressed and go downstairs.

One way to correct a comma splice is by subordination--that is, by using a subordinating conjunction.

Example: Because someone is at the door, I need to get dressed and go downstairs.

Semicolons are used instead of commas to separate items in lists if the items themselves contain commas.

Example: The specialties at that clinic are endocrinology; ophthalmology; ear, nose, and throat; and neurology.

Clauses that are written that way are not necessary for understanding the meaning but tend to provide extra detail. The commas are there to avoid confusion by making the main meaning or subject of the sentence more clear.

"Therefore" is a transitional word and traditionally a comma is placed after the word to indicate the transition. For example:

The economy of the United States was historically based upon agriculture; therefore, a proposed tariff on exported cotton was extremely unpopular with Congress.

There is not a single rule, because whether you use a comma with "because" and where you would use it depend on how you are using "because".

The first sentence is an example of a common situation, in which "because" introduces a dependent clause. In this situation, you use a comma before "because".

In some situations, you don't need any commas:

The game was delayed because of rain.

Because his interview was the best of the lot, he was our first choice to fill the position.

In other situations, you would put a comma both before and after "because":

I have to cancel our lunch, because, as it turns out, I will be in Helsinki.

It can, however it is considered optional. For example, take these sentences.

I'm going to the store to buy milk, cheese, and eggs.

I'm going to the store to buy milk, cheese and eggs.

Both are considered correct.

Okay.

"Los Angeles, Ca; Tokyo, Japan; Hong Kong, China; Sydney, Australia."

"She missed work three times in a row; her boss fired her."

"I miss my friends; they all moved away."

Yes, you should put a comma before "as" when it is used as a conjunction in a sentence.

A colon is typically used to introduce a list when the introductory clause or phrase sets up the list that follows. A hyphen can be used to introduce items in a list when each item is being elaborated upon or when the list items are closely related.

Yes, a sentence with quotation marks can also have commas. For example: "She said, 'I'll be there at 5 p.m.,' but she didn't arrive until 6 p.m." In this sentence, the commas are used within the quotation marks to set off the quoted speech.

It all depends on the keyboard in use.

In the UK - ":" (Colon) and ";" (Semi-colon)

A comma is typically used before a conjunction (e.g., and, but, or) when joining two independent clauses. However, a comma is not generally used before a preposition, unless it is necessary for clarity or emphasis.

Yes, a colon can precede the word "because" when introducing an explanation, a list, or a summary of information. It is a common punctuation usage in formal writing to provide clarity and emphasis on the reason or cause that follows.

They are called Punctuation sings.

i love him and i want him to come to emerld

Commas join two clauses where at least one of the clauses is dependent and doesn't make a complete sentence on its own. If both clauses could each make their own sentence if alone, a semicolon is used instead.

In some cases, yes.

It's usually a bad idea, however; the more common usage is for the semicolon to precede the word.

It may help to ask yourself "would this still make sense if the semicolon were a period?" If so, then the semicolon is probably in the right place.

There's really no reason to ever use a semicolon if you don't know how to do it properly. 99 44/100 % of the time a period will work almost as well. (The 0.56% where it won't? Programming languages.)

No. The placement of commas has more to do with the flow of the sentence; there are no unbreakable rules for placing commas before or after certain words. Even placing a comma before the word and is correct under certain circumstances.

You can use either a semicolon or a comma before "however" depending on the context. Use a semicolon to separate two independent clauses, and use a comma when "however" is used as a conjunctive adverb to connect two sentences.

No, it is not always necessary to use a comma before "and" when connecting two independent clauses. It depends on the style guide you are following. In American English, a comma before "and" in such instances is known as the Oxford comma and is generally optional.

No, a comma before "as appropriate" is not necessary. It depends on the context of the sentence and whether it flows better with or without the comma.

Yes, there should be a period after "BLVD" and a comma after before "SUITE" in an address format. For example: 1234 Main Street, BLVD., SUITE 101.
