Oh, dear, I get so confused. Even my Grandma can't teach me grammar. In a recent entry I wrote
Later in the morning it will ask for BOB, whoever he is.
Shouldn't that be whomever? I think that pronoun is the object of the clause whoever he is. Whomever would be the objective case. AND wait another minute: that is an independent clause. How come it is hanging onto BOB with a comma. That should be a period, or a least a semi-colon
Fifty-five years ago I was teaching high school English, and would have known. Now I got no grammar at all.
