Hyphens and Dashes

A hyphen joins two or more words together (e.g. x-ray, door-to-door) while a dash separates words into parenthetical statements (e.g. She was trapped - no escape was possible.

Hyphens:

Generally, hyphens are used to avoid confusion or ambiguity but today most words that have been hyphenated quite quickly drop the hyphen and become a single word (e.g. e-mail andemail, now-a-days and nowadays). In many cases though a hyphen does make the sense clear:

• I am thinking of re-covering my sofa (to put a new cover on it)
• I would like to recover my sofa. (perhaps from someone who has borrowed it as this means 'to get it back')

Hyphens and numbers

1. Use a hyphen with compound numbers from twenty-one to ninety-nine.

• fifty-one
• eighty-nine
• thirty-two
• sixty-five
• eighty-one

2. In written fractions place a hyphen between the numerator and denominator.

• two-fifths
• one-third
• three-tenth
• nine-hundredth

[Exception] if there is already a hyphen in either the numerator or the denominator, you omit the hyphen between the numerator and denominator.

• sixty-nine eighty-ninths (not 'sixty-nine-eighty-ninths')
• twenty-two thirty-thirds

3. Use a hyphen when the number forms part of an adjectival compund:

• France has a 35-hour working week.
• He won the 100-metre sprint.
• Charles Dickens was a great nineteenth-century novelist.

Usage

Consult your dictionary if you are not sure but remember that current usage may be more up-to-date (not uptodate... yet!) than your dictionary. There are some cases where hyphens preserve written clarity such as where there are letter collisions (co-operate, bell-like) or where a prefix is added (anti-nuclear, post-colonial), or in family relations (great-grandmother, son-in-law.)

Dashes:

Dashes can be used to add parenthetical statements in much the same way as you would use brackets. In formal writing you should use the bracket rather than the dash as a dash is considered less formal in most cases. However, they should not be overused nor used to replace commas although they can be used to create emphasis in a sentence.

Examples

• You may think she is a liar - she isn't.

Brackets and Parentheses

The difference between a 'bracket' and a 'parentheses' can be a bit confusing.

Generally, parentheses refers to round brackets () and brackets to square brackets []. However, we are more and more used to hearing these refered to simply as 'round brackets' or 'square brackets'.

Usually we use square brackets - [ ] - for special purposes such as in technical manuals. Round brackets - ( ) -, or 'parentheses' are used in a similar way to commas when we want to add further explanation, an afterthought, or comment that is to do with our main line of thought but distinct from it.

Many grammarians feel that the parentheses can, in fact, be replaced by commas in nearly all cases.

For example:

• further explanation - The government's education report (April 2005) shows that the level of literacy is rising in nearly all areas.
• comment - I visited Kathmandu (which was full of tourists) on my way to the Himalayas for a trekking expedition.
• afterthought - You can eat almost anything while travelling in Asia if you are careful to observe simple rules (avoiding unboiled or unbottled water is one of the main rules to be aware of.)

 The Colon

The colon expands on the sentence that precedes it.

• There are many reasons for poor written communication: lack of planning, poor grammar, misuse of punctuation marks and insufficient vocabulary.
• He collected a strange assortment of items: bird's eggs, stamps, bottle tops, string and buttons.
• Peter had an eclectic taste in music: latin, jazz, country and western, pop, blues and classical.
