Explanations (just in case, I know I'm toeing the line on some): Ganda is an ethnic group in Uganda. Aceso is the Greek goddess of healing; Antaeus is the monster son of Poseidon and Gaia; Serra has a few meanings (and is a reasonably common name), but I was going with the missionary, Junipero Serra (for historical figure context, just in case). Nervii were a Belgic tribe from Roman times. The rest might not be used daily for most people, but have standardized/commonly understood definitions I think most people would know (all fit well enough into the "vocabulary test" category/not too obscure).
