"Mangio il pesce arrosto."

[arnie.bell]

is it grilled fish or roasted fish

[giuliap]

It should be roasted. Grilled fish is pesce alla griglia.

[carleila]

Perhaps this is a difference between different forms of English but in England, certainly, we say 'roast pork', 'roast beef ' [not 'roasted']. So it would be good to see 'roast' accepted as an alternative answer.
I don't believe I have ever heard 'roast' (nor 'roasted') applied to fish. And I agree with others that 'grilled' (alla griglia) is not the same thing.

[TheGandalf]

Yeah, it now seems to accept "roast" as correct. Yay!

[nr38449]

Difficult to hear the difference between mangia and mangio here. And as there is no "Zusammanhang", there is nothing else to go on.

[italikaren]

How would you say "the fish roast"? l'arrosto di pesce? because I wrote "I eat the fish roast" and it was wrong.
