Arthit

Arthit is also used as a feminine name in Thai. However, it's more common for males. So, I think that the "Gender" of this name should be changed from "Masculine" to "Masculine & Feminine". Some evidence for this is that Arthit is also used as a name element in unisex and feminine Thai names, such as Athittaya and its variant transcriptions.
