Periods

Periods have many uses:
·        Complete Thoughts
·        Abbreviations
·        Ellipsis
·        Decimal Points


Complete Thoughts

Periods are used to signal the end of a complete thought.

·        The photocopier is broken.
·        I have never visited the museum.

A complete thought can include the following:

Declarative Sentences
·        I like hockey.
·        She lives in France.

Indirect Questions
·        My co-worker asked me if I had the file.
·        She asked him about his project.

Imperative Sentences (Instructions)
·        Please bring the documents to the meeting.
·        Do not arrive late.

If a sentence ends in an abbreviation, it is not necessary to add another period.

        I have never visited P.E.I..

        I have never visited P.E.I

However, if the abbreviation is at the end of a question, include the period and the question mark.

        Have you ever visited P.E.I?

        Have you ever visited P.E.I.?


Common abbreviations with all capital letters do not normally take periods.  For example,
·        WHO (World Health Organization)
·        IMF   (International Monetary Fund)


Ellipsis
3 periods together are called an ellipsis.  This is used with quotations to show missing words.
·        "The current world economy will improve next year...jobs will be created at a faster pace."

Decimal Points
Use periods as decimal points to separate numbers.
·        3.4
·        2.57
·        $19.99, $17.34

Spacing
Periods are followed by either 1 or 2 spaces between sentences.  The most important rule is to stay consistent.  If you follow a period with 2 spaces, do not change to 1 space in the same document.
