- Attributed speech (e.g. 'he said', 'they yelled' etc - things where the person's action is a form of speech) should follow a comma at the end of the speech. i.e. it's:"My name is Giddeon," he said.
and not"My name is Giddeon." He said.
The second one leaves 'he said' as a sentence of two words that doesn't work on its own.
The same applies to quotation marks and exclamation marks followed by things like 'he said' as well. Although it would normally be a sentence ending punctuation mark, it isn't with attributed speech.
Note, though, that non-speech actions should leave speech ending with a fullstop, e.g."He was known as Giddeon." He rubbed his hands together involuntarily as the memories flowed back to him. - Make sure that you use commas to separate long sections of description - partly to break it up instead of being in one long breath, but partly to add clarity. Just to borrow an example of 'comma clarity' from Brannick:The giant Bloodthirster gestured towards two smaller daemons that swooped over the three marines carrying a large bronze slab.
is ambiguous. Is it the three Marines that are carrying the bronze slab, or is it the daemons? A comma after the word 'marines' clarifies it.The giant Bloodthirster gestured towards two smaller daemons that swooped over the three Marines, carrying a large bronze slab. - If a sentence is getting particularly long and unwieldy, try breaking it down into a number of smaller sentences. Don't try to describe lots of slightly related things in one sentence and get a huge sentence. Instead, use a number of small sentences to describe all of the sub-areas of the scene.
Hopefully those points should be useful and help people improve their FanFiction And now to go and partly blame my fiancee and her beta reading website for making me pick up on even more of those errors than I used to
