My name is Kristina and from what I gather, it is reasonably common in russia (its on the list of widely used girls names on this site). I was wondering if it has a diminutive. When I was born, my Grandparents wanted me to have a diminutive and amongst my family and russian friends I am called Kristya. I was wondering if this a common diminutive for Kristina and if not, what is? Also my sister is named Natalia, I know that Natasha a common diminutive for it but it is common for that then to be shortened to Tasha, because that is what she is called like I am called Kristya.
