I once read a short love story by a Catalunyan author that was written in first person, with the gender of the narrator’s beloved left intentionally ambiguous through most of the story – which is quite impressive for Catalunyan, Spanish or any of the related languages. I wish I remembered its name or the author.
I’m sorry to bother you again, but I just re-found this ask, and I’m taking an online course in gender and sexuality (in spanish), and for last week’s assignment we read this short story written in first person by a woman that is almost always gender ambiguous till the end, and it was written by a Catalanuyan author, so, maybe?
