Dyn ni wedi dysgu hoffwn i - I would like. Nawr, dyn ni'n mynd i ddysgu dweud gallwn i - I could a dylwn i - I should.
Mae hi'n braf heddiw - gallen ni fynd i'r parc.The weather's fine today - we could go to the park.Gallwn i wneud brechdanau i ni.I could make sandwiches for us.Gallai'r plant chwarae ar y siglen.The children could play on the swing.Gallet ti fwydo'r hwyaid.You could feed the ducks.
Mae hi'n bwrw glaw heddiw. Dylen ni aros yn y tลท.It's raining today. We should stay in the house.Dylet ti lanhau'r gegin.You should clean the kitchen.Dylai'r plant gymoni'r teganau.The children should tidy the toys.Dylwn i smwddio'r crysau.I should iron the shirts.
