"Your ear needs surgery."

Translation: Mae angen llawdriniaeth ar eich clust.

[AlanNason]

Why not 'Mae angen eich clust llawdriniaeth'?

[EllisVaughan]

That would have to be "Mae eich clust angen llawdrinieath". Remember Welsh is a Verb-subject-object language so the thing doing the verb must come second in the basic sentence structure.

[MargaretWe2]

I wrote, "Mae dy glust angen llawdriniaeth." and was marked incorrect. Does that not work the same as your example, but informal? Or, is there something I'm missing?
