Having never read Earthly literature or grammer rules I will study these rules closely;
"3) Freds have no distinct genders. The correct pronouns with which to refer to freds are hesheit (nominative case), himherit (oblique/objective case), and hishersits (possessive). However some freds look decidedly male or female to human perception."

It may even help communication with my cross dressing son.

( I've noticed it takes about 4,000 years for a popular language to lose all need for pronouns like the Chinese.)

hmmm? Can one be a hybrid freds and not know it? Also do freds have unusually long lifespans.
