Status B
Subject: Law
Part of speech: Noun, Masculine, Singular
Plural: closedau dŵr
Definition: Mewn ystafell ymolchi gyhoeddus, ciwbicl sy’n cynnwys cyfleusterau lle defnyddir dŵr i olchi’r gwastraff ymaith.
Notes: Dyma’r term technegol (ar y ffurf ‘water-closet’, gyda chysylltnod) a geir yn Neddf Adeiladau 1984, a seiliwyd y diffiniad yn y cofnod hwn ar y diffiniad yn y Ddeddf honno. Ar y cyfan, mae’n ymadrodd sydd wedi dyddio. Yn y rhan fwyaf o gyd-destunau lle y’i gwelir bellach, mae’n debyg y defnyddir ‘water closet’ (ac yn enwedig ei acronym, WC) mewn ystyr lai penodol ac yn gyfystyr â ‘toilet’ yn yr holl ystyron sy’n bosibl i’r gair hwnnw. Bryd hynny, mae’n debyg y byddai ‘toiled’ yn addas yn Gymraeg.
