"That is fine."
Translation:Dat is prima.
Is 'prima' not better than 'fine'? When something is 'fine', it is 'okay' or 'agreeable' - would something that is 'prima' not be 'excellent' / 'super' / 'really great' / 'fantastic' etc? 'Prima' relates to 'first' or to the number one - indicating that it is the best outcome? If somebody did a fantastic piece of work and your response is that is 'fine', your are telling that person that his work is acceptable, while in fact his work is much more than 'fine'.
You are over analysing the word prima. In this context prima == fine.
Sure it can also mean excellent etc. but that is generally the case when it is followed by a noun.
