Comma, ``,``

============

 1. Separate items in long lists.

    prepositional phrase.

    the final element of a list (for purists).

    relative clauses.

 6. Use a comma if your subject has two or more adjectives describing it.

  [6] The powerful, resonating sound caught our attention.

Colon, ``:``

============

 1. Colons precede a list, an explanation or an example.

 2. The colon is used to separate two main clauses where the first is an

    introduction to the second.

 3. To introduce a direct quote (a comma can also be used in this

    situation).

 4. You do not put a space before a colon, but you do need a space after

    one.

Examples::

      Victoria Centre.

  [2] The pilot had an awful realization: he had forgotten to turn off the gas

      at breakfast time.

  [3] He announced to his friends: "I'm getting married!"

Full stop (period), ``.``

=========================

 1. Full stops (periods in the USA) go at the end of sentences that are

    statements.

 2. They are also used to mark abbreviations. If such an abbreviation occurs at

    the very end of a sentence, the final dot is not written twice.

 3. You do not put a space before a full stop, but after one.

Examples::

  [1] My name is Lynn. I am a teacher.

  [2] An overhead projector is often referred to as an O.H.P.

Hyphen, ``-``

=============

* Hyphens are used to connect words or syllables, or to divide words into parts.

* You don't use a space on either side of a hyphen.

Examples::

  There were ninety-nine red balloons.

Question mark, ``?``

====================

 1. Question marks go at the end of sentences that are questions.

 2. You need a question mark at the end of tag questions.

 3. For quotes within quotes, use single quotes.

 4. You do not put a space before a question mark, but after one.

Examples::

  [1] Is my name Lynn? Of course it is.

  [2] It's a nice day, isn't it?

Semicolon, ``;``

================

 1. Semicolons are used to separate two sentences that would otherwise

    be joined with a word such as 'and', 'because', 'since', 'unless' or

    'while'. 2 To separate groups of words that are themselves separated

    by commas.

 2. You do not put a space before a semicolon, but you do need a space

    after one.

Examples::

  [1] I'm looking forward to our next lesson; I'm sure it will be a lot of fun.

  [2] They plan to study German, for their travels; chemistry, for their work;

  and literature, for their own enjoyment.

Quotation mark (speech mark), ``""``, ``''``

============================================

Double quotes ``""``, single quotes ``''``.

 * Quotation marks (single or double) are used to show words that are

   directly spoken (direct speech).

 * Only the words actually being quoted are enclosed by speech marks.

 * You need a space before the opening speech mark, but no space after

   it, and a space after the closing one, but no space before it.

 * Another general rule is to use a comma after the introduction to

   quoted speech or writing.

 * Sometimes when writing a spoken sentence it is split in two. The

   speech marks must then be placed at the beginning and end of each

   part of the sentence. Commas are used to separate the spoken part

   from the rest of the sentence.

 * If you need a question mark or exclamation mark the markers that

   punctuate the quoted words are enclosed by the speech marks.

Examples::

  "Could everyone sit down please," said the teacher.

  Jaime said, "I love you."

  "I wonder," she said quietly, "whether people will ever truly understand each other."

  "I don't understand," replied Nathan.

  "Do you understand?" asked Nathan.

  "I don't understand!" shouted Nathan.

  Nathan replied, "I don't understand."

  Nathan asked, "Do you understand?"

  Nathan shouted, "I don't understand!"

  He wrote in 1946 that, "The key word in digital computer is 'digital'."

Ellipsis, ``...``

=================

 1. Ellipsis used to show that something has been omitted, indicate

    missing words in an incomplete quotation.

Examples::

  [1] Chomsky suggested that, "Language is a system that...can be described in

      an algebraic notation."

Dash, ``-``, ``--``

===================

 1. The dash should be used when making a brief interruption within a

    statement, a sudden change of thought, an additional comment, or a

    dramatic qualification.

Parentheses ``()``

==================

 1. Use parentheses to clarify, to place an afterthought, or to add a

    personal comment. Be sure to include the period after the closing

    parenthesis.

Examples::

  [1] Steve Case (AOL's former CEO) resigned from the Time-Warner board of

      directors in 2005.

  [1] You will need a flashlight for the camping trip (don't forget the

      batteries!).

  [1] Most grammarians believe that parentheses and commas are always

      interchangeable (I disagree).

Brackets ``[]``

===============

 1. Use brackets to signify an editor's note in a regular piece of

    writing. You can also use brackets to clarify or to revise a direct

    quote so that it appeals to your own writing.

 2. The first brackets are rounded, and brackets inside brackets are

    squared.

Examples::

  [1] "[The blast] was absolutely devastating," said Susan Smith.

Slash ``/``

===========

 1. Use the slash to separate "and" and "or", when appropriate.

 2. The slash can replace the word "and" to join two nouns.

 3. The slash is used when quoting lyrics and poetry to denote a line

    break. Be sure to add spaces between your slashes here.

Examples::

  [1] To register, you will need your driver's license and/or your birth

      certificate."

  [2] The student/part-time employee has very little free time.

  [3] "Row, row, row your boat / gently down the stream / life is but a dream."
