I have a simple question...
when you use "should" in a sentence with the 3rd. person how do you write the verb?
I think that is in this way: " He/She Should KNOW " without the s in the verb, but someone told me that when you use it in question way thatīs the correct way.. but if itīs an afirmation you should write it like " He/She should KNOWS " with the third termination in the verb.
So I am confused.
thanks for your help
She should know
After a modal verb, we don't add the -s. I'm afraid the person who told you that is wrong.
