Referring to a single person who may be of any gender in English can be tricky. It can be awkward to use words like "one" or phrases like "he or she," and many a grammarian hates using "they" as to refer to a single person. How has English gotten this far without such a convenient pronoun? Actually, it hasn't.
Students and teachers in Vancouver, British Columbia, can now use the gender-neutral pronouns "xe," "xem," and "xyr." The move is designed to accommodate students for whom "he" and "she" does not fit or is deemed inappropriate.
