Although vaguely off topic, one thing that grinds my gears is calling Persian "Farsi". Nobody goes around saying "hello I speak Español" but for some reason, rather recently, it has become popular to use the endonym for Persian in place of the already well established "Persian". I've more than once met people not knowing they are the same thing which is sad because using the new word loses well-rooted associations like with famous authors and other cultural elements etc

There are several persian languages, so referring to the one you mean as "Farsi" makes it more clear (as opposed to "Tajiki" or "Dari" for example).

That's an afterthought, in English you say Levantine Arabic or Egyptian Arabic, or Brazilian Portuguese, Bavarian etc not "Bayrisch" or "al-lahje shamiye" or something else
