what the difference between uruk hai and orcs
Uruk-hai Christopher Tolkien describes "Uruks" as an anglicization of "Uruk-hai" and his father used the two terms interchangeably a number of times. While "Uruk-hai" means simply "Orc-folk", the term was reserved for the soldier orcs of Mordor and Isengard. The larger orcs called the smaller breeds snaga ("slave").
