Transgender means someone that routinely ( not necessarily consistently ) transitions from one gender to another. Gender is one's outward reflection of the male-female gender -spectrum-
Transexual is someone who actually opts to go through an operation to change their gender to fit the female-male dichotomy.
Neither are offensive terms. Tranny could be because doesn`t designate which is which.
