Dialogue//:
The dialogue is how a character speaks. Some people don't quite understand this. Usually, it gets a paragraph to its self. The dialogue is separated in quotations. (("words.")). The usual way to end dialogue is with the punctuation of the tone of however it's being spoken. With an exclamation mark (!), question mark (?), or period (.).
Incorrect||: "I can't stand the sting in my arm."
Correct||: "I can't stand the sting in my arm,"

Incorrect||: "I can't stand the sting in my arm." she complained.
Incorrect||: "I can't stand the sting in my arm," She complained.
Correct||: "I can't stand the sting in my arm," she complained.

It's the same if the "she/he said" comes before the dialogue:

Incorrect||: She complained "It'll be a pain to use it."
Incorrect||: She complained, "It'll be a pain to use it."
Correct||: She complained, "It'll be a pain to use it,"

The dialogue can work the same if an action comes between it. The only difference is, is that when the sentence continues the first word isn't capitalized due to it being the same sentence.


Incorrect||: "Well, I guess I can try," she whined, "But it'll be hard."
Incorrect||: "Well, I guess I can try." she whined, "but it'll be hard."
Correct||: "Well, I guess I can try," she whined, "but it'll be hard."

The comma thing can be ignored if something is used other than a comma. Like an exclamation mark, or question mark. If "he/she said" is following the sentence, use the comma. It's a permanent thing.

Incorrect||: "Damn it," he shouted.
Correct||: "Damn it!" he shouted.

Correct||: He yelled "This keeps happening to me!"
Correct||: He yelled, "This keeps happening to me!"

Incorrect||: "So," he started, "Do you think he'll say okay?"
Correct||: "So," he started, "do you think he'll say okay?"



Run-on Sentences//:
Only two sentences can be connected, and that's with certain words. Those are for, and, nor, but, or, yet, and so. A semicolon can combine sentences. As for a group of words, they do not count as run-on sentences.

Incorrect||: "He looked to the side, and she had left so it was time to go."
Correct||: "He looked to the side; she had left, so it was time to go."
Correct||: "He looked to the side, and she had left; therefor it was time to go."

Homophones//:
This is a word that sounds the same as another word, although it's spelled differently and most of the time has a different definition to it. These often cause people to make mistakes, and screw up what you're writing to make the sentence difficult to comprehend.

--Effect and Affect||:
Effect// Result: a change or changed state occurring as a direct result of action by somebody or something else.
Affect// An influence somebody or something: to act upon or have an effect on somebody or something.

Your and You're||:
Your// Belonging to person spoken to: refers to something that belongs to or relates to the person who is being spoken to.
You're// You are. It's the combination of the two words. Like isn't is 'is not'.

There, They're, and Their||:
There// In or to that place: used to indicate position in or motion toward a place relatively distant from the speaker.
They're// They are. Like you are is you're.
Their// Belonging to them: belonging to or relating to a specific group of people or things.

The list goes on, but those are just the select few that people mess up. Try looking into it in order to know you're talking about the right word.
