Linguistics
In English, ethnonyms are generally formulated through suffixation; by applying an -n to people of Austria, their nationality is known as Austrian. In English, in many cases, the word for the dominant language of a group is identical to their English-language ethnonym; the French speak French, the Germans speak German. This is sometimes erroneously overgeneralized; it may be assumed that people from India speak "Indian", despite there being no language which is called by that name.
Generally, any group of people may have numerous ethnonyms associated with the political affiliation with a state or a province, with geographical landmark, with the language, or another distinct feature. Ethnonym may be a compound word releted to origin or usage, polito-ethnonym indicates that name originated from the political affiliation, like Belgian for inhabitants of Belgium that have their own endonyms; topo-ethnonym refers to the ethnonym derived from the name of the locality, like Uralians for the inhabitants of the geographical area near the Ural mountains that have their own distinct endonyms. Classical geographers frequently used topo-ethnonyms (demonyms) as substitute for ethnonyms in general descriptions or for unknown endonyms. Compound teminology is widely used in professional literature to discriminate semantics of the terms.
