Is this a sentence? If so, what does this mean?
I'm not sure what the Welsh meaning would translate into; but what Duolingo says the English translation is, is how I would say "I think it's very common" personally.
Oh, I think I get it. It helps if I think about it as a line of dialogue, but I'm afraid my mind is so inflexible that it took me forever, and your help, to understand that it simply needs a comma.
comma added, thanks for the discussion.
