Notes: Sylwer y defnyddir 'demise' yn gyfystyr â 'lease' weithiau. Mewn defnydd technegol iawn ym maes cyfraith eiddo, mae 'demise' yn cyfeirio at drawsgludiad les yn hytrach na'r les ei hun. Pan ddefnyddir 'demise' yn gyfystyr â 'lease' gellid defnyddio 'les' yn Gymraeg, ond dylid gwirio'r union ystyr ym mhob achos.
