Pictish was the extinct Brittonic Celtic language spoken by the Picts, the people of eastern and northern Scotland from late antiquity to the Early Middle Ages. Virtually no direct attestations of Pictish remain, short of a limited number of geographical and personal names found on monuments and early medieval records in the area controlled by the kingdoms of the Picts. Such evidence, however, shows the language to be an Insular Celtic language β possibly a variant of the Brittonic language once thought to be spoken in most of Great Britain.
The prevailing view in the second half of the 20th century was either that Pictish was a non-Indo-European language isolate, or that there coexisted not one but two Pictish languages: one Indo-European (Brittonic Celtic branch) and the other non-Indo-European.
