This fact irritated me greatly. What, the greatest linguists that speak the English language can't be bothered including us? Or are they just very ill-informed and think all transgenders fall under "->-bleeped-<-" which they *did* remember to include.

Perhaps there is some one I can write to and request that linguists be more trans-sensitive..

aah, should have specified myself. I meant any published dictionary, since it was an online dictionary definition that I stumbled across and thought ".. my god, that's me .. there's a word for me!"

It's in this dictionarry (Dictionary.com)
1.    a person who has undergone a sex change operation [syn: transsexual]
2.    a person whose sexual identification is entirely with the opposite sex [syn: transsexual]

Oxford Dictionary of the English Language, 1992

Merriam-Webster's Collegiate Dictionary, Eleventh Edition, 1999

My more recent dictionary has that word, and the older unabridged one I got for Christmas has the word "transfeminize," so I will give it some progressive credit, considering it was published in the '70s.  Both are Merriam-Webster, I believe.  The newer one may be the very edition tekla speaks of; I am pretty sure I got my dictionary sometime around then, when I was somewhere in the age range of 6-10.
