What is "cigfa"

Cigfa ferch Gwyn Glohoyw ( Middle Welsh: Kigua) is a minor character in Welsh mythology, the wife of King Pryderi of Dyfed. She is mentioned briefly in the First Branch of the Mabinogi, and appears more prominently in the third. Describing the character, Proinsias Mac Cana writes: "Cigfa strikes one as a slight though effective vignette of a contemporary bourgeois snob while William John Gruffydd hypothesises that the character was a later addition to the tale." John Rhys suggested a connection between Cigfa and the Irish character Ciochba.
