forgot to actually post my #DecRecs last night so here it is!
Did you know that you can download the entirety of the Chicago Assyrian Dictionary for free online? I mean, okay, probably like me you don't have a lot of really good reasons to look up the meanings of Akkadian words. Most of us are not out here trying to read cuneiform tablets in their original language.
But if you want, say, character names for a fantasy setting (it might also be useful for historical stuff set in ancient Mesopotamia but for names there you should probably look into sources specifically about names then), then consider Akkadian! The language is likely unfamiliar to your players/readers/whatever regardless of their cultural background, so it will help to make your setting feel unfamiliar; names like "Nablu" or "Paharu" probably won't have prior connotations, which isn't always an advantage but can be useful; as with any use of a consistent naming language, the use of it will allow you to hint at connections and relations even to an audience which is unaware of the meanings of the elements.
Also it's just neat to randomly page through and read about a long-dead language.
