Grammar 101: insider tips and tricks to instantly improve your writing (part 4)
Punctuation makes your writing easier to read and understand, but it can be tricky to master. As an editor and proofreader, I often notice people confusing semi-colons and colons, so we'll explore the difference between them. And because both are often used in lists, we'll also look at the humble comma – and its sometimes-controversional cousin, the Oxford comma.?
Semi-colons and colons both connect phrases in a sentence but are used in different situations.?
Understanding colons
Colons introduce important information and explanations. They're often used before lists as a replacement for phrases like "they are" and "which is":
- He offered me a choice of drinks: tea, coffee or hot chocolate.?
- I packed the essentials in my bag: water, pens and a magazine.?
- She speaks three languages: English, French and Portuguese.?
You can also think of a colon as a spotlight, with the phrase that comes after the colon explaining or expanding what came before it.?
- In 1903, travel was changed forever by an important event: Orville and Wilbur Wright's first successful flight.
- He loves visiting the animals at the farm: cows are his favourite.?
- There is one rule I live by: I treat others as I wish to be treated.
The secrets of semi-colons
A semi-colon links two ideas that are closely related and that would be two complete sentences if you used a period instead. They give a softer transition than a period would, and they're often used instead of conjunctions like "and", "but" and "because":
- I love eating pizza; my sister loves eating burgers.
- I wanted to go for a swim; I couldn't find my goggles.?
- It was the best of times; it was the worst of times.
Semi-colons also seperate items in long lists to make life easier for the reader and stop a sentence becoming a sea of apostrophes. For example:
- I've got my shopping list ready: peppers, carrots and oranges from the market; toothpaste, shampoo and pain relief from the drugstore; and a newspaper, snack and drink from the newsstand. ?
Standard comma or Oxford comma?
An Oxford comma goes before "and" or "or" at the end of a list. The first example has an Oxford comma, the second doesn't.?
- Please bring me a sandwich made with cheese, lettuce, and tomato.?
- Please bring me a sandwich made with cheese, lettuce and tomato.?
American English generally favors the Oxford comma, British English typically omits it, unless needed for clarity. Compare:
- I love my parents, Taylor Swift and Keanu Reeves.
- I love my parents, Taylor Swift, and Keanu Reeves.?
As with many areas of punctuation, whether you choose to use the Oxford comma is a matter of personal preference. However, the most important thing is to be consistent in your usage.?
