Part of speech: Verb
Definition: Y broses i leihau risgiau amgylcheddol a risgiau iechyd a diogelwch i lefel dderbyniol.
Context: Ddiwedd 2020, cyflwynodd Llywodraeth Cymru gynllun grant er mwyn i’r awdurdodau lleol fedru gwneud y gwaith hwnnw, gan gynnwys gwaith cyweirio ar domenni lle bu llithriadau, megis yn Tylorstown a Wattstown.
Notes: Cyfyd y term hwn mewn nifer o gyd-destunau cyfreithiol, gan gynnwys y ddeddfwriaeth i sicrhau diogelwch tomenni glo a sicrhau diogelwch adeiladau. Yng nghyd-destun tomenni glo mae'n golygu gwneud gwaith i sicrhau diogelwch tomenni, ee gwaith i'w sefydlogi. Yng nghyd-destun adeiladau mae'n golygu disodli nodweddion anniogel â nodweddion mwy diogel, ee gwella nodweddion diogelu rhag tân. Yn aml yn y cyd-destunau hyn rhaid gwahaniaethu wrth gysyniadau â ddisgrifir yn Gymraeg â'r term "adfer" (neu "restore", "restoration" yn Saesneg). Ond mewn rhai cyd-destunau llai technegol lle nad oes posibilrwydd o amwysedd, mae'n bosibl y gellid defnyddio "adfer" i gyfleu "remediation".
