The term "Prince with a Thousand Enemies" used in the prelude is a direct translation of the rabbit folk hero El-Airarah's name.

Occasionally the rabbits use terms which are not explained in the movie, but which are featured in Richard Adam's novel, along with their meanings. For interest, some of these are: "owsla"=a term for a selected band of rabbits responsible for both security and raiding parties (for vegetables, mostly; organization varies with the warren); "hraka"=rabbit droppings or something similarly offensive; "tharn"=mad or paralyzed with fear; "elil"=any rabbit-killing/-eating enemy; "hrududu"=generic term for motorized vehicles; "zorn" (which Holly cries out right before he joins the others near the new warren)=catastrophe; "Frith"=the sun; "Inle"=the moon, or death; "hlessi"=a wandering rabbit.
