More About Zie
Zie/ze enjoy a degree of popularity among gender-neutral pronouns however some find that when the zir/zirs/zirself pronouns are used the “z” sound at the start of the word can disappear when the words are employed after any words ending with “s” or “z” sounds, leaving some forms of the pronouns to sound like the feminine “her”. Additionally when the hir/hirs/hirself option is employed confusion with “her” can also be problematic even though the pronunciation is different (“here”).
