Note: A thousand years ago Old English words had masculine and feminine forms. "Wicca" was masculine and "Wicce" was feminine. That changed several centuries ago. Unlike French, Spanish and other modern languages, English has not had gendered nouns for several centuries. In Modern English, "Wicca" has no gender and is inclusive.
Pronunciation: In Old English a "c" preceding a front vowel "e" or "i" was pronounced "ch," so the Old English feminine form, "Wicce," was pronounced "wich-e." A "c" preceding a back vowel "a," was pronounced hard as "k." In Old English "Wicca" was pronounced "wik-ka." In current usage "wicce" has morphed into "witch," and "Wicca" is pronounced "wik-ka."
