Readers should note that the above post used the _Albanian_ form of this name, and compare with the Britannica's reference:
https://www.britannica.com/place/Kosovo
"The name Kosovo is derived from a Serbian place-name meaning “field of blackbirds.” After serving as the centre of a medieval Serbian empire, Kosovo was ruled by the Ottoman Empire from the mid-15th to the early 20th century, a period when Islam grew in importance and the population of Albanian speakers in the region increased."
Then research the political background behind the recent use of "Kosova" form.
