Je was op zoek naar: is knowledgeable (Engels - Wels)

after all , if a local council is knowledgeable about an issue , that issue is local roads
wedi'r cyfan , un o'r materion y dylai cyngor lleol fod yn hyddysg amdano yw ffyrdd lleol

with due respect to brian , i know that he is knowledgeable about such matters but neither jane nor i , nor our officials have that expertise
 phob parch i brian , gwn ei fod yn ddeallus mewn materion o'r fath , ond nid yw'r arbenigedd hwnnw gan jane na minnau , na'n swyddogion

he is also a notable person as he has vast experience of parliamentary procedure and is knowledgeable about constitutional matters , which will be of great assistance to him in his new post
mae hefyd yn berson nodedig am fod ganddo brofiad helaeth o weithdrefnau seneddol ac mae'n wybodus ar faterion cyfansoddiadol , a fydd yn gymorth mawr iddo yn ei swydd newydd
