Welsh: Du

Status A

Subject: General

Part of speech: Adjective

Definition: Fel disgrifiad o bobl, mae ‘Du’ gan amlaf yn cyfeirio at hunaniaeth sy’n tarddu’n wreiddiol neu’n rhannol o Affrica islaw’r Sahara. Gall fod ag elfennau diwylliannol yn perthyn iddo, ac felly nid yw’n cyferbynnu bob tro â ‘gwyn’ lle nad oes yr un ymdeimlad o berthyn i hunaniaeth arbennig.

Notes: Daw'r term hwn o gasgliad y Grŵp Gorchwyl a Gorffen ar Derminoleg ym maes Cydraddoldeb o ran Hil ac Ethnigrwydd. Diffiniad a nodiadau defnydd y Grŵp a gofnodir gyda'r cofnod hwn: "Hyd y bo modd, defnyddiwch briflythyren gyda’r gair ‘Du’ wrth gyfeirio at bobl, a dim priflythyren gyda ‘gwyn’ mewn cyd-destunau tebyg. Yr unig eithriad yw lle mae angen cysondeb rhwng dwy ddogfen yn y ddwy iaith a bod yn rhaid i’r cyfieithiad ddilyn arddull y gwreiddiol. PEIDIWCH â defnyddio ansoddeiriau lliw yn enwol (h.y. yn lle enwau) wrth gyfeirio at grwpiau o bobl e.e. ‘y Duon’ / ‘y gwynion’. PEIDIWCH â defnyddio ffurfiau lluosog yr ansoddeiriau ‘du’ a ‘gwyn’ wrth gyfeirio at bobl (h.y. ‘pobl Ddu’ nid ‘pobl Dduon’, a ‘pobl wyn’ nid ‘pobl wynion’). Mewn rhai ymadroddion, e.e. ‘bywydau Duon’ gallai ymddangos fel petai ‘Duon’ yn enwol yn hytrach nag yn ansoddeiriol a gwell osgoi hynny, fel y nodir uchod."

Notes: Daw'r term hwn o gasgliad y Grŵp Gorchwyl a Gorffen ar Derminoleg ym maes Cydraddoldeb o ran Hil ac Ethnigrwydd. Diffiniad a nodiadau defnydd y Grŵp a gofnodir gyda'r cofnod hwn. "Peidiwch â defnyddio’r term na’r acronym Saesneg ‘BAME’ os oes modd ei osgoi, gan ei fod yn tramgwyddo rhai pobl y mae’n ceisio’i ddisgrifio, drwy grwpio a chyffredinoli a phwysleisio rhai grwpiau gan eithrio eraill. Caiff ei gynnwys yma yn unig er mwyn rhoi arweiniad i'r rhai sydd yn gorfod ei drosi i’r Gymraeg. Defnyddiwch y term Cymraeg llawn yn unig os oes angen cyfateb i’r Saesneg ‘BAME’. O ddewis, disgrifiwch pobl yn ôl eu cymuned ethnig unigol, nid yn ôl lliw croen na chategorïau gorgyffredinol. Os oes rhaid cyffredinoli, defnyddiwch ymadrodd fel ‘cymunedau ethnig amrywiol’ (‘diverse ethnic communities’) neu ‘mwyafrif byd-eang’ (‘global majority’)."
