Where Commas Fear to Tread

What a comma CAN’T do

 ‘Not commas again’, I hear you groan.

Well… yes, because I promised (or threatened) a post about semicolons. Semicolons step in where commas (should) fear to tread.

She walked on without stopping, Jayne had always known how I felt about her.

WRONG

This is called a comma splice, where two perfectly complete, standalone sentences are joined with a comma, instead of being separated with a full stop (or a period, to my US readers).

There are three ways to avoid a comma splice:

1)   Separate the clauses into two sentences.

She walked on without stopping. Jayne had always known how I felt about her.

2)   Join them using one of the words and, or, nor, but, yet or for (known as coordinating conjunctions) preceded by that comma.

She walked on without stopping, yet Jayne had always known how I felt about her.

3)   Change the comma to a semicolon.

She walked on without stopping; Jayne had always known how I felt about her.

So far, so easy.

Just to confuse us…

(there’s always something, isn’t there?)

Several websites add rules for clauses joined by subordinating conjunctions.

These are words like moreover, nevertheless, consequently, likewise, however, otherwise, therefore, namely, finally, then, also…  and ‘joining phrases’ such as, as a result, or that is. . .

Subordinate clauses rely on the first clause in some way and can be joined with a semicolon.

She walked on without stopping; however, Jayne had always known how I felt about her.

Tip

Having only just discovered this rule, I’ve since realised I don’t need to remember it. Neither do you.

I usually write such clauses as separate sentences.

She walked on without stopping. However, Jayne had always known how I felt about her.

Therefore, when I do join them, perhaps to vary sentence lengths, I use a semicolon so as not to create a comma splice.

Which brings us back to where we started and would be a good place to stop, wouldn’t it? 

Sadly, there is more.

What a semicolon CAN’T do

A semicolon cannot join an independent clause and a dependent one.

WRONG

She walked on without stopping; showing she didn’t care about my feelings.

CORRECT

She walked on without stopping, showing she didn’t care about my feelings.

To use a semicolon, each side of the semicolon must form an independent clause that could stand on its own as a sentence.

There is another use for semicolons.

Semicolons with too many commas

Comma-studded lists

When a list includes items which themselves have commas (or are confusingly long), use semicolons to separate the items.

The choice for supper was fish and chips; ham, egg and chips; sausage, baked beans and chips; or pie and chips.

The family is now scattered between Chippenham, Wiltshire; Bath, Somerset; and Poole, Dorset.

Comma-studded clauses

Similarly, when the first independent clause contains one or more commas, semicolons can be used with a coordinate conjunction.

She walked on, ignoring me, and turned the corner; but Jayne had always known how I felt about her.

In the same way that semicolons emphasise the start of a new item in a comma-studded list, they can emphasise the start of a new clause after a comma-studded first clause.

Or you could start a new sentence with that But. (Yes, I know your teacher told you never to start a sentence with And or But. That was then. Now it’s acceptable. Sometimes. . .)

A word about colons

Well, several words. . .

Colons introduce lists and anything else you’re about to define or explain.

Mum gave us a choice for supper: fish and chips; ham, egg and chips; sausage, baked beans and chips; or pie and chips.

The family is now scattered between three counties: Wiltshire, Somerset, and Dorset.

A colon signals that more information is on the way. Think of those two dots as an abbreviation of that is, or ie.

(But if you actually use that is as a joining phrase,  put a semicolon before it – see subordinating conjunctions, above.)

The family is now scattered between three counties; that is, Wiltshire, Somerset, and Dorset.

A colon can emphasise contrast

 Note that the clause before the colon is always a complete sentence: unlike the clause after it.

Sadly, colons seem to be out of fashion, especially in fiction, where they are often replaced by a dash, which is less formal, or just a comma.

Note that the clause before the colon is always a complete sentence – unlike the clause after it.

I hope this has helped a little. It helped me. I learned something while checking my facts.

As always, an online search will find further examples of all these points and more.

NEXT TIME…

Who knows?

It won’t be punctuation.

I’ve had enough of punctuation (does it show?)

  1. Now I know more about colons, semi-colons, and commas then I do about my own children’s lives! And by the way, it’s complicated! I’m so glad you’re going to beta read my book! I need you to email me an address where I can send your soft copy? Thanks for sharing all this information! I intend to continue abusing commas but at least I know now that I’m breaking all the grammar rules. xxoo, C

    1. I suspecct I overuse them. You can live without them abd be correct, but sometimes they’re exactly the connector you need. Modern preference seems to be to eliminate all but the most basic punctuation though. Colons seem to have all but disappeared in fiction..
