Here are some possibilities:
* If it's a name of Arabic origin, it's likely pronounced "GAY-nah" with a short "a" sound.
* If it's a Greek name, it might be pronounced "GEH-nah" with a long "e" sound.
* If it's a variant spelling of "Jenna" or "Gena," it would be pronounced accordingly.
Without more context, it's impossible to determine the correct pronunciation. If you can provide more information, such as the origin of the word or its meaning, I can give you a more accurate answer.
