ze
pron.— «For those who are not familiar with ze/hir, it is used rather than she/her or he/him/his for some people who identify outside of a man/woman dichotomy. Like he and she, ze has several forms that are not particularly easy for the average person to classify grammatically (he, she, ze; his, her, hir; him, her, hir; his, hers, hirs; himself, herself, hirself), but anyone who can use she and he is capable of integrating ze.» —“Ze/hir pronouns represent future in spite of linguistic conservatism” by Pira Kelly in University of Oregon Oregon Daily Emerald (Eugene) May 12, 2005.
