"Marcus and Corinna go to the market."
Translation:Marcus et Corinna ad forum eunt.
I have left out "the" and been marked wrong, when putting this from Latin to English. In my part of the world (UK) I believe "go to the market " is what the customers say and "go to market" is what the farmers say when going to sell their produce. Just now most of the markets are locked-down and the "supermarkets" are picking up their business.
