Diffiniad a nodiadau defnydd y Grŵp a gofnodir gyda'r cofnod hwn: "Defnyddiwch briflythyren lle bo modd i adlewyrchu dimensiwn diwylliannol y disgrifiad hwn o bobl. Yr unig eithriad yw lle bo angen cysondeb rhwng dwy ddogfen yn y ddwy iaith a bod yn rhaid i’r cyfieithiad ddilyn arddull y gwreiddiol."
