I have a character that is of indeterminate gender. Not a main protagonist, but an important player nevertheless. I generally refer to the individual by name, rather than using a gender specific nominative pronoun. However I tend to struggle in situations where I would instinctively use a gender specific possessive pronoun, especially when describing complex physical movement (dancing or boxing for example.) I find that using a plural pronoun as a singular, such as 'they' 'theirs' and 'them' to get past this problem to be a clumsy alternative to a singular pronoun - they just don't flow as well, like a bump in the road. So I'm toying with the idea of utilising either the Spanish gender neutral possessive 'su' or a made-up pronoun similar to the so-called Spivak pronouns ('e' 'em' and 'eir' ). But given that these terms are not true members of the English language, they too can at first jar the mind and eye, or at least until you are used to seeing them. I read a book recently (On The Steel Breeze by Alastair Reynolds) that used the terms 've' 'vis' and 'ver' when referring to a specific character, and I actually quite liked their use. But certain critics disdained their use, claiming that it detracted from the work. Does anyone have any thoughts on this?
