Abi

Abi is also used as a masculine name in English, as a diminutive of Abraham, Abram, Albert, Abel, etc. Abi is also used as a unisex diminutive of Abijah. However, it's more common for females. So, I think that the "Gender" of this name should be updated from "Feminine" to "Feminine & Masculine".
