People across the world come to Twitter to discuss what’s happening, and we want our service to better reflect the many voices that shape the conversation. In some languages, such as Arabic, words can be feminine or masculine, but we’ve missed a way for people to tell us how they want to be addressed. So today, we're introducing a new language setting that acknowledges and better supports the Arabic feminine form.
People who select this setting will be addressed in the feminine form. For example, “Tweet” will be غرّدي (which addresses women) rather than the default Arabic today, which is غرّد (addressing men). Also, “Explore” will be إستكشفي rather than إستكشف.
I'm trying to think of other languages where the gender is intrinsic, but i can't think of the usual cases of the third person (he/she) in roman or Germanic languages. Those are not really used when addressing other people, as seems to the case here with Arabic. Korean does have gender specific ways of addressing people, but those can easily circumvented.
So, can you think of other languages where such a option would make sense?
