I will post a dictionary excerpt at the end which shows the uses of whether.Originally Posted by Anonymous
This is OK. I prefer "I am going to the party whether or not you want to go.1# I am going to the party whether you want to come with or not.
I don't know whether (or not) to tell her the truth. (The "or not" is optional.)2# I don't know whether or not to say her the truth.
It is incorrect. "Giving him the knife back" is a gerund phrase, acting as a noun. Whether needs more than a noun after it.3# I don't know whether giving him the knife back.
I feel 3# is incorrect.But I am not sure. So please help me solve my doubt.
"I don't know whether giving him the knife back is the right thing to do.
