There are basically five punctuation errors that every writer must avoid. These are: 1. The Comma Splice - Two sentences joined only with a comma.
Example: He fell into the pool of water, his clothes soaked up the cold wetness. This should be two sentences.
2. The Run-On Sentence or Fused Sentence - A sentence containing two complete thoughts jammed together unnaturally.
Example: Edward's skin lit up like a nuclear bomb his face shining gloriously as if to blind the world.This should be two sentences or should be revised to incorporate both thoughts.
3. The Sentence Fragment - A sentence that does not contain a complete thought.
Example: I can find the horcrux. If I wanted to. Either combine the sentences or finish the thought of the second phrase.
4. Dialogue Rules - All dialogue should be surrounded by quotation marks ("") and each time a new person speaks, there should be a new paragraph... unless you are James Joyce.
5. Apostrophes -
Apostrophes indicating possession:
- This is the girl's doll. One girl owns this doll.
- This is the girls' doll. More than one girl owns this doll.
- These are the girls' dolls. More than one girl owns more than one doll.
Apostrophes indicating letters missing from words:
- I can't find my hat.
- I'll get right on that.
- It's not okay to write about sparkling vampires.
