Sanskrit (/snskrt/; Sanskrit: samskrtam [smskrtm] or samskrta, originally samskrta vak, "refined speech") is the primary sacred language of Hinduism, a philosophical language in Buddhism, Hinduism, Sikhism and Jainism, and a literary language that was in use as a lingua franca in Greater India. It is a standardised dialect of Old Indo-Aryan, originating as Vedic Sanskrit and tracing its linguistic ancestry back to Proto-Indo-Iranian and Proto-Indo-European. Today it is listed as one of the 22 scheduled languages of India and is an official language of the state of Uttarakhand. As one of the oldest Indo-European languages for which substantial written documentation exists, Sanskrit holds a prominent position in Indo-European studies.
Besides its uses as language of religions, for what other application can Sanskrit be used?

Serbo-Croatian was standardized in the mid-19th-century Vienna Literary Agreement by Croatian and Serbian writers and philologists, decades before a Yugoslav state was established. From the very beginning, there were slightly different literary Serbian and Croatian standards, although both were based on the same Shtokavian subdialect, Eastern Herzegovinian. In the 20th century, Serbo-Croatian served as the official language of the Kingdom of Yugoslavia (when it was called "Serbo-Croato-Slovenian"), and later as one of the official languages of the Socialist Federal Republic of Yugoslavia. The breakup of Yugoslavia affected language attitudes, so that social conceptions of the language separated on ethnic and political lines. Since the breakup of Yugoslavia, Bosnian has likewise been established as an official standard in Bosnia and Herzegovina, and there is an ongoing movement to codify a separate Montenegrin standard. Serbo-Croatian thus generally goes by the ethnic names Serbian, Croatian, Bosnian, and sometimes Montenegrin and Bunjevac.
What were both Serbian and Croatian standards based off of?
Eastern Herzegovinian

Many of the leading universities associated with Enlightenment progressive principles were located in northern Europe, with the most renowned being the universities of Leiden, Gottingen, Halle, Montpellier, Uppsala and Edinburgh. These universities, especially Edinburgh, produced professors whose ideas had a significant impact on Britain's North American colonies and, later, the American Republic. Within the natural sciences, Edinburgh's medical also led the way in chemistry, anatomy and pharmacology. In other parts of Europe, the universities and schools of France and most of Europe were bastions of traditionalism and were not hospitable to the Enlightenment. In France, the major exception was the medical university at Montpellier.
Which six universities were the most renowned in northern Europe?
Leiden, Gottingen, Halle, Montpellier, Uppsala and Edinburgh
