I put female because is the gender of the letter in Spanish, as it is the neuter in Greek, in which it was written. That's why I noticed that the Greek version talked about the letter, but this is a good question.
To sum up, Evulitsa speaks Greek much better than any of the members (if ever they do) who questionned her work and voted against this translation. It's about time to settle this one.
Thanks Guilon. To respond sara costa, I think it's improbable this solution (u=you in englizh) since in Greek has a determinative neuter article... Thanks for your observations!
