That's fascinating. In German and in Polish every word has a gender. In Polish you even cannot hide your gender while talking about yourself in the past tense, because the form of verbs you use will reveal your gender. (that's why I like writing in the www in English)
And you don't even need the pronoun, because the verb's form also includes that.
I think Latin works this way: Veni, vidi, vici - (I) came, (I) saw, (I) won.
It's maybe why I always find it irritating not immediately knowing a gender if someone writes my friend, or doctor, or teacher - English speakers are used to get the information from the context, I expect it from the words themselves.
Do you know Latin? I always wonder. Do you know diffrent words?
