- Double preposition? 5 answers
So you open the door and see your friend and say "Come on in" that means you are asking him/her to come in, okay? But then I read in a book that it was wrong English but it did not mention what was the correct form.So that is my question.
What is the grammatically correct English phrase or sentence having the same meaning as "Come on in" and according to which particular rule this one is wrong ?
EDIT: This was from a story book written in my native language and it's from a conversation between two characters. One says "Come on in" and the other thinks to himself "speaking wrong English." This might seem strange but I really wanted to know what would be the right English and hence this post.
