Deheubarth (Welsh pronunciation:[dɛˈhəɨbarθ]; lit.'Right-hand Part', thus 'the South')[4] was a regional name for the realms of south Wales, particularly as opposed to Gwynedd (Latin: Venedotia). It is now used as a shorthand for the various realms united under the House of Dinefwr, but that Deheubarth itself was not considered a proper kingdom on the model of Gwynedd, Powys, or Dyfed[5] is shown by its rendering in Latin as dextralis pars or as Britonnes dexterales ("the Southern Britons") and not as a named land.[6] In the oldest British writers, Deheubarth was used for all of modern Wales to distinguish it from Hen Ogledd (Y Gogledd), the northern lands whence Cunedda originated.[7]

^The orientation of Medieval maps and geographical thinking was towards the east. Facing east, north was thus on the "left-hand" side and south on the right.
