If I am not mistaken, in this instance the masculine form derives from the feminine rather than the other way around. The word for "preparation" is Paraskeve (feminine).
Paraskeve was a saint who was born on Friday and that's how she got her name, because Paraskeve means Friday in Greek. I praise this saint and wouldn't mind having this name. A short way to pronounce it, at least in Greece, would either be "Voula" and Paresa", for a girl, and "Paris", for a boy.

The Albanian form is Parashqevi. I have read that it is quite common among Albanian Orthodox Christians.
