NA	not applicable
unknown	unknown

There are three genders in the Hebrew Bible, singular (sg) and plural (pl) and a much rarer dual (du). Not all words have number (e.g. adverbs) and these are marked as NA. There are words that do have number, but whose number class is unknown to us, because they only occur in forms that do not mark it; these are marked as unknown.
