I'm not looking for a definition at all; I'm perfectly comfortable with the primary definition of 'of or going to the root or origin; fundamental.' I'm not going to dispense with perfectly reasonable vocabulary just because alternative interpretations of a term exist.

If you're not sure what someone means, consider asking them rather than complaining about it. Transitioning to a different gender from one's birth default is (for the time being) a radical change involving extensive medical evaluation, a lifetime drug regimen and ultimately major surgery, to say nothing of the social difficulties.
