Countries where the language is the same word as the citizens

[LSLGuy]

Here is a recent thread on almost the same topic:

Noun for language but not for speakers?

Many nouns for languages also are the cultural/ethnic noun (loosely) for the speakers. For example : French: May refer to the language and Or the people English : may refer to the language or the people Spanish : may refer to the language or the people Hindi is a language spoken in India but there is no such thing as “Hindi people”. Are there other languages that fall into category ? I am guessing Yiddish and Aramaic are nouns for the language but not the people. Is that correct ?
