OK, some people on here are REALLY GOOD at getting all their punctuation and spelling right. I wondering if we can get some tips. I'm fair to middling myself but thank God for spell check! There are still plenty of times I'm wondering if I'm getting my punctuation, apostrophes, spelling, etc. right. I'll start with a few examples of things I have trouble with. (Did I just end a sentence with a preposition? LOL) Apostrophes: "Here is the dog's house." Apostrophe before the "s" in "dog's", right? "The dog went into its house." Is there supposed to be an apostrophe before the "s" in "its" or not? Why? The use of periods with quotes: In my example sentences from above should the period be inside the quotes or outside? What are the rules on that? Use of quotes: When should I use quotes and when shouldn't I? Did I do it right in this post? When do you use single quotes and when do you use double quotes? Well, that should get us started. Thanks for the help!
