@TulliusCicero: the only true genderless language is Persian. There is no he, she, it even. There is no way to hear if someone is man or woman without a precise context or asking "Man or Women?", which I often hear Iranians ask in Conversations.
https://en.wikipedia.org/wiki/List_of_languages_by_type_of_g... begs to differ. There are whole language families without genders.
