I had to choose the right sentence among three, and the correct one used "facem pește". Is that an usual way of saying "we cook fish" in Romanian?
Why "la wineri" is not correct?
Shouldn't it be vinerea? vinerea = on friday, right?
Why is pesti not accepted?
It could work in a very specific scenario, like if you'd really want to empathize that you are cooking more than one fish. But it is very unlikely.
Otherwise, you'd just say pește. Same for poultry (pui), pork (porc), beef (vită) and so on.
Defintely still confused as to when la is used before a day of the week etc
