Super glad the Eorzibethean basics infographic is useful! :3 I've seen in a couple of places folks looking for a wordlist as well. This stuff is super relaxing for me, so conscripting @davetheshady once more into helping put a quick Eorzibethean wordlist together.
The words that follow were selected by the extremely scientific method of skimming Urianger's lines in Dialogue Collection FFXIV and @uriangertxt and being like hey that's a fun word, gimme one of those, yeah I'll take one of them, and that one too…and then sprinkling in a couple more just for the heck of it. If you think of any others please pop them in the comments and I'll add them!
The short definitions are from our heads and my favorite toy a great resource, the Online Etymology Dictionary, which is linked on each for further reference and linguadorking.
