"You must move now!"

Translation: Mae rhaid i ti symud nawr!

[Tawelfan22]

Why not "Rhaid i chi symudwch nawr!" Doesn't the exclamation point make this an imperative?

[ibisc]

In the rhaid i pattern, it has to be followed by the verb-noun (symud in this case) not by a verb (such as symudwch)

[Tawelfan22]
