Welsh: neilltuo
Subject: Cyllid ac ystadegau
English definition: In Central and Local Government, this is often used with the same meaning as ring-fence.
Welsh definition: Nid 'pridiannu' y dylid ei ddefnyddio yn y cyd-destun hwn. Ond byddai'r gair hwnnw'n briodol i gyfleu'r ystyron ‘to pledge [money] by law to a specific purpose; to place or assign as security under an arrangement’.
