Do you use a colon or semicolon before a list

Rule 1: Use the colon after a complete sentence to introduce a list of items when introductory words such as namely, for example, or that is do not apply or are not appropriate.

Examples:
You may be required to bring many items: sleeping bags, pans, and warm clothing.
I want the following items: butter, sugar, and flour.
I want an assistant who can do the following: (1) input data, (2) write reports, and (3) complete tax forms.

Rule 2: A colon usually does not precede a list unless it follows a complete sentence.

Examples:
To be successful in sales, one should do the following: (a) dress appropriately, (b) ask customers about their needs, and (c) follow through.

To be successful in sales, one should (a) dress appropriately, (b) ask customers about their needs, and (c) follow through.

Rule 3: With tabular format, a colon customarily precedes a list. If the introductory statement is a complete sentence and the listed items are complete sentences as well, the listed items are capitalized and punctuated as complete sentences.

Examples:
To be successful in sales, one should do the following:
(a) Dress appropriately.
(b) Ask customers about their needs.
(c) Follow through.

If the listed items are each a separate completion of the introductory statement, the listed items are punctuated accordingly and are not capitalized.

To be successful in sales, one should:
(a) dress appropriately.
(b) ask customers about their needs.
(c) follow through.

It is also acceptable to use and before the last phrase, making the listed items a continuation of the introductory statement. As continuations, they would be punctuated with commas and not capitalized.

To be successful in sales, one should:
(a) dress appropriately,
(b) ask customers about their needs, and
(c) follow through.

Note:
Similar treatment can be applied to single words or phrases in list form, including bullets, or numbers. The rule of thumb is to be consistent.

To be successful in sales, one should:
 dress appropriately,
 ask customers about their needs, and
 follow through.

To be successful in sales, one should:
• dress appropriately.
• ask customers about their needs.
• follow through.

Note: With lists, you may use periods after numbers and letters instead of parentheses.

Semicolons help you connect closely related ideas when a style mark stronger than a comma is needed. By using semicolons effectively, you can make your writing sound more sophisticated.

Rules for Using Semicolons

• A semicolon is most commonly used to link (in a single sentence) two independent clauses that are closely related in thought. When a semicolon is used to join two or more ideas (parts) in a sentence, those ideas are then given equal position or rank.
  

  Some people write with a word processor; others write with a pen or pencil.

• Use a semicolon between two independent clauses that are connected by conjunctive adverbs or transitional phrases.
  

  However they choose to write, people are allowed to make their own decisions; as a result, many people swear by their writing methods.

• Use a semicolon between items in a list or series if any of the items contain commas.
  

  There are basically two ways to write: with a pen or pencil, which is inexpensive and easily accessible; or by computer and printer, which is more expensive but quick and neat.

• Use a semicolon between independent clauses joined by a coordinating conjunction if the clauses are already punctuated with commas or if the clauses are lengthy.
  

  Some people write with a word processor, tablet, or even a phone; but others, for different reasons, choose to write with a pen or pencil.

Avoid using a comma when a semicolon is needed:

Incorrect: The cow is brown, it is also old.
Correct: The cow is brown; it is also old.

What’s going on here? Both parts of the sentence are independent clauses, and commas should not be used to connect independent clauses if there is no coordinating conjunction. This mistake is known as a comma splice.

Incorrect: I like cows, however, I hate the way they smell.
Correct: I like cows; however, I hate the way they smell.

What’s going on here? The conjunctive adverb however signals a connection between two independent clauses, and commas should not be used to connect independent clauses if there is no coordinating conjunction.

Incorrect: I like cows: they give us milk, which tastes good, they give us beef, which also tastes good, and they give us leather, which is used for shoes and coats.
Correct: I like cows: they give us milk, which tastes good; they give us beef, which also tastes good; and they give us leather, which is used for shoes and coats.

What’s going on here? It’s unclear what the three list items are, since the items are separated by commas.

Incorrect: Cows, though their bovine majesty has been on the wane in recent millennia, are still one of the great species of this planet, domesticated, yet proud, they ruminate silently as we humans pass tumultuously by.
Correct: Cows, though their bovine majesty has been on the wane in recent millennia, are still one of the great species of this planet; domesticated, yet proud, they ruminate silently as we humans pass tumultuously by.

What’s going on here? It’s unclear where the first independent clause ends and the second independent clause begins.

Avoid using a semicolon when a comma is needed:

Incorrect: Because cows smell; they offend me.
Correct: Because cows smell, they offend me.

What’s going on here? The first part is not an independent clause, so no semicolon is required.
