Answer Question
"Avete la stessa in un altro colore?"
I don't understand why "la stessa" is feminine in this situation. Sonia goes on to explain that "lo stesso colore" means "the same color" but says nothing about the fact that "la stessa" is presented in feminine form. Besides, I thought that "the same" was referring to "il vino", which is masculine! So why isn't "stessa" also masculine?
