The English Language Needs a New Word.

I don't know what it will sound like or how to spell it. I just know that again and again I run into the terrible grammatical predicament of he/she. If a writer does not know the sex of a referenced person, they , he/she, he or she, hi, ho hum, ek, ugh, too many options. All look bad.

We need a word that replaces he/she.

Any suggestions? It has to be short and easy on the tongue, because it will be used all the time. I never studied linguistics, though I'd like to, but from what I understand, the point of grammatical rules is to make language sound more elegant. Even though English doesn't sound nearly as elegant as some languages, like Spanish, yet more elegant than Chinese, IMHO.

Hit me. Hit me!
