"Cân nhw lasied o lemonêd yr un, plîs."

[sam.eckmann]

I wrote "May they please each have a glass of lemonade", and it wasn't accepted. I'm not sure if there was anything wrong with that sentence?

[ibisc]

This sentence has used the positive statement form - 'they will have' cân nhw. The question form has a soft mutation - 'may they have? gân nhw?.
