Igama elibhalwe ngesiNgesi elithi Germany lisuka kwigama lesiLatini elithi Germania, gama elo elaqala ukusetyenziswa emva kokuba uJulius Ceasar wathi waliphakamisela abantu basempuma yeRhine.[17] Eyona icacileyo, yoyokokuba ngu-Gauls owaqalayo ukubiza abantu ukuba bawele impuma yeRhine Germani (neyathi yasetyenziswa ngamaRoma) njengoko uhlanga lwemveli lwamaJamani lwalungazibizi ngamaGermanus okanye amaGermani. Ngoko ke eli gama lasetyenziswa kuphela kumhlaba wamaRoma kwaye lanika intsingiselo ethe chatha kubantu ababeyixhasa impuma yeRhine kunye/okanye umntla weDanube. [18] Igama lesiJamani elithi Deutschland (ngokwemveli diutisciu land, ""umhlaba wamaDatshi"") lisuka kwisiDatshi, isizukulwana esisuka kuluntu lwamaDatshi akudala olwaziwayo(i.e. bengamaDiot okanye ""amaDiota""), lisetyenziselwa ukwahlula ulwimi lwabantu nje kwisilatini nakwisizukulwana samaRoma.
