There are some pairs of words my OCD will not allow me to use in a sentence, because I have no idea which word is correct. When you’re just talking, some are ok because they sound the same, but when you’re typing you have a record of having used the wrong word. So, would anyone like to help me out here? Any little memory jingles, or succinct grammar rules, or a general outline of which word to use when… really any help at all would be appreciated. I also have a huge fear of ending sentences incorrectly, so any rules about how not to end a sentence would be nice.
it's / its
affect / effect
lie / lay
past tense of swing (we swung? we swang? I usually end up saying we were swinging)
