would this mean naughty like he's silly/mischievous or would it more mean "he is behaved very badly"?
The latter would be the case, i think.
Finally a sentence I can use every day! (dog not amused)
Cant we say mean instead of bad?
Mean is stronger than bad. In Finnish both can be translated to paha. A dog is naughty (tuhma) if it pees on the carpet. It is bad (paha) if it bites you
Another cute sentence...now
I am in love with this course
