The Illinois Department of Public Health has a very comprehensive drop-down menu for picking your preferred language, which is good, except that it is so comprehensive that it includes "English, Middle (1100-1500)" and "English, Old (ca. 400-1100)" right under English, also there's "Egyptian (Ancient)", "German, Old High ca. 1050-1500", "Irish, Old (to 900)", "Low Saxon", and, maybe most perplexingly, "Indo-European languages"
@Pixley i bet it would be pretty easy to find where the developer stole this list from lol
@Pixley yep, it's ISO, of course https://www.loc.gov/standards/iso639-2/php/English_list.php
