Letter O
We could say that the letter O is the sign of the neutral gender. Your companions would be the letter E , the sign of the masculine gender and the sign of the g & eacute; female nero would be the letter A .
If we had a number of two digits ... when the tens digit is equal to the unit count, the gender is said to be neutral. When the tens digit is less than the unit count, the gender is said to be masculine. But when the unit count is less than the tens digit, the gender is said to be feminine.
An example:
For the two-digit number ... 52, the gender would be female.
For the number ... 25 the gender would be male.
For the number ... 55 the gender would be neutral
