Call A Rabbit A Smeerp: Almost inevitably, thanks to Translation Convention, and purging of jargon and dialog of obvious Earth-culture references, like, say, “Sorcerer’s Apprentice Problem” and “Newtonian mechanics”.  Although at least most of the time, it is trying to indicate some subtle difference: making the distinction between “agorism” and “capitalism”, for example, the latter being a loaded term for most potential readers.  And the oft-referenced bandal, for example, isn’t quite the same animal as the Earth dog (although sharing a common origin; see under Ancient Astronauts again), due to their short separate evolution and breeding for different qualities, as you can tell from the size difference, greater paw-manipulation ability, and larger braincase.
