Almost nothing is known about the Pictish language except that it was spoken in central and northern Scotland before the ninth or tenth century.

Other than a handful of proper names and place names, the Pictish vocabulary is almost entirely unknown. Linguists can't even agree entirely as to whether the language most resembled Welsh or Gaelic or something else. (Welsh is the favorite nowadays.)

While the Wemyss Caves do contain a wealth of Pictish carvings, it would be good to know the source of the idea that "wemyss" was the Pictish word for cave. The Gaelic word is "uamh" (pronounced "oo-av") and the Welsh is "ogof."
