“Or perhaps “arlwydd pwys” means “the legitimate lord,” in opposition to usurpers, just as a wedded wife is styled “gwraig bwys,” as distinguished from a concubine.”

Y Gododin A Poem of the Battle of Cattraeth

“Rhuawn Bevr, ab Gwyddnaw Garanhir; sev yu gelwid felly achaws rhoddi eu pwys yn aur am danynt o ddwylaw au lladdes.””
