i've used random word generator programs to great effect in the past. you can use country, region, and town names of a specific language as input, and the program will then generate random nonsense words that sort of sound like they come from the same language.
here's some examples that i've used recently.
French: Rhevollon, Langens, Prelounne, Aigne, Vailmaulon, Pacage, Hyx, Amiton, Monorel, Vantou, Moirelle, Melors, Narogne, Nelpen, Alacanen, Nessins, Mantelle, Lenuelfe, Darmonet, Besolon, Troussance, Derny, Gorelle, Beyhaunde, Larenne
Greek: Granapsis, Taratis, Epaxos, Iodima, Cadymia, Stibos, Padaraea, Hirastos, Maliphrace, Astera, Eubythra, Enelchus, Carypa, Serons, Adocia, Seroniphis, Edarastes, Phetis, Lasupeia, Hexipanae, Trymaea, Pyrgaspa, Nissitus, Beutharia, Acalymos, Aphenia, Dodortus, Tramis, Talipeia, Thyges
Italian: Coggeno, Frelbano, Cirenza, Livino, Fascalo, Pallamo, Lotorno, Santevo, Vantalia, Tacceli, Trastocia, Vezzoni, Osintario
Romanian: Batedala, Astazu, Drenos, Dravea, Vinacea, Tutaniu, Warina, Orj, Campuva, Varabava, Slarzova, Prusira, Canirza, Zedara, Colj, Bagera, Slivunu, Vircu, Barav, Morcana, Oncaviu
if anyone's interested, the free shareware program can be downloaded
here, and i currently have data files for Arabic, Armenian, Celtic, Egyptian, English Town Names, Ethiopian, French, Georgian, Greek, Hindi, Italian, Malay, Persian, Phoenician, Romanian, Sumerian, Swahili, Turkish, West African, and Star Wars Planet Names. i want to do Spanish, German, Scandanavian, and Russian at some point in the future, to complete the "major" languages of Europe.
i'd be more than happy to email the data files to whomever might want them.
edit: just realized it looks like email has been turned off on the boards. if you want my data files, go
here.
