nor usually follows a neither when they're used in the same sentence (1). For example, you might say, “I like neither hot dogs nor mustard.” You may also use nor if you’re talking about more than two items, but you must repeat nor after each element (2). So if you want to add ketchup to your list of dislikes, you have to say, “I like neither hot dogs nor mustard nor ketchup.” It would be incorrect to use an or anywhere in that sentence—or to leave out either case of nor. Neither can appear at the beginning of a sentence as well as the middle. For example, “Neither the man nor the woman is a good surfer” is nice and balanced.
