Sandile is also used as a feminine name in Zulu, Xhosa, and Ndebele, alongside Andile, Ayanda, and Bandile. However, Sandile is more common for males. So, I think that the "Gender" of this name should be changed from "Masculine" to "Masculine & Feminine".Sources: https://www.names.org/n/sandile/about https://forebears.io/x/forenames/sandile
