Pictus

Superficially from Latin pictus (“painted one”), but probably rendering a Pictish autonym, probably related to the origin of another Celtic tribe, the Pictones (compare Poitiers); perhaps from a Proto-Celtic *Kʷritanī, *Kʷritenī, the Goidelic/Q-Celtic version of the Brittonic/P-Celtic *Pritani, whence Welsh Prydyn (“Picts”), Old Irish Cruthne, Cru(i)then-túath (“Picts”), ultimately from Proto-Indo-European *kʷer- (“to do”). Guto Rhys has noted a possible connection to Old Welsh Peithan, perhaps attesting the same element as Welsh gobaith (“hope”), although the etymology is uncertain, it would presumably derive from a Proto-Brythonic *pext-.
