archimandrite

I have a distant relative who is an Archimandrite of the Greek Catholic Church, (a high bishop akin to the Cardinal of the Roman Catholics). He started out as a priest in a Carpatho-Russian congregation, St. John's in Perth Amboy, NJ. I always loved the sound of that word, archimandrite, and wondered about it's origin. Eastern Rite priests are allowed to marry, BTW.
