Its great that you have published such knowledge. I just hope these are all reliable. It would be better if you also include in your page the references that you are using. Thanks!
We have derived and refined our rules over the years from many textbooks on grammar and punctuation and have kept up with the evolving changes to the English language by consulting authoritative reference works such as The Chicago Manual of Style and The Associated Press Stylebook. Including references for every rule would detract from the intent of presenting rules and examples in a simple, easy to understand, and tempting to use format.
Thanks Jane.
You’re welcome.
Hi, You’re doing a very good work by writing these useful articles. Can you tell me out of these two sentences, ” it’s me” and “its i” , which is a correct one? Do we use “me” or “i” in these kind of sentences?
Thanks
Our blog “I vs. Me” addresses this question. The rule says, “Use a subject pronoun following state of being verbs such as am, are, is, was, were.” However, the blog also notes the important distinction between spoken and written language. The formal, written response would be, “It is I.” However when spoken informally, one would be more likely to say, “It’s me.”
