Definition: ffurfio barn (ynghylch rhywbeth), yn enwedig wrth ddal bod sefyllfa yn wir os bodlonir amodau penodol neu yn absenoldeb tystiolaeth i'r gwrthwyneb
Context: Os yw’r cyfan o gais apelio neu gais hawlio yn cael ei ddileu o dan baragraff (5), bernir bod yr achos y mae’r apêl neu’r hawliad yn ymwneud ag ef wedi ei derfynu.
Notes: Defnyddir “barnu” os defnyddir “deemed” yn ferfol, e.e. “consent is deemed to have been given”, “bernir bod cydsyniad wedi ei roi”. Fodd bynnag, os defnyddir “deemed” fel ansoddair, defnyddir “tybiedig”, e.e. “deemed consent”, “cydsyniad tybiedig”.

Yn gyffredinol ym meysydd cynllunio a’r gyfraith, gan gynnwys yng nghyd-destun yr amgylchedd hanesyddol, ffefrir gwahaniaethu rhwng ‘cydsyniad’ (consent) a ‘caniatâd’ (permission). Yn y gorffennol, yn achlysurol defnyddiwyd ‘caniatâd’ i drosi ‘consent’, ond nid yw hyn yn gymeradwy bellach gan fod angen gwahaniaethu rhwng y cysyniadau hyn.
