Some more tidbits:
Free Companies and Grand Companies are actually taken from real world history - ironically they actually referred to the same thing, organized groups of mercenaries who operated independently of governments in the Middle Ages (roughly analogous to modern day 'independent military contractors') - where as in FFXIV only FCs are actual 'mercenary groups' with GCs the volunteer military forces of each citystate. This explains why during the 2.X storylines when FCs are mentioned by npcs, they're referred to in less than shining terms and are regarded as little more than groups of sellswords and ruffians.
Limsa Lominsa is referred to officially as the 'Thalassocracy'. A thalassaocracy is a system of government which is essentially a state that holds power over the oceans - in the strictest sense, it is one where all their 'territory' is maritime and not land based, which definitely suits Limsa to a tee (not surprisingly, the word thalassocracy is again a Greek word, the Greek citystates after all were strong maritime powers in the Ancient world and actually Eorzea's citystates are very loosely based on).
Pugilist is another word for boxer - the actual origin of the world pugilism is somewhat unclear, but at it's basic it refers to bare-knuckle fistfighting (as opposed to modern boxing which uses gloves that cover the fists), somewhat ironic given the PGL class in FFXIV is forced to use brass knuckles, cesti and other hand weapons. ;)
