"The fourth one is the good one."

Translation: A patra e cea bună.

[jasonbc123]

I'm a little lost on how this Romanian sentence translates into 'The fourth one is the good one.'

To me, the Romanian sentence 'A patra e cea bună' would translate to 'The fourth is the good'. or better yet 'The fourth is the best'

Can someone kindly explain this to me?
