Correct Endings for Sindarin Names

[Esteliel]

How can I properly convert genderless Sindarin names into male and female ones? I have one specific name in mind: Calaear. I would love to use it for a character, but I can't seem to settle on the correct way to feminize that name. Every attempt I've made thus far has that character sounding like one of my Mary Sues from back in the dark days of junior high.
