Can this also mean "The boy is taking a large bite.", as in a bite of food?
It can! :) For taking a large piece, you can also say "gutten tar et stort stykke".
"Stor bit" is not acceptable as "big piece "???
He got hungry during communion XD
hva er forskjellen mellom 'en bit' and 'en del'?
The audio sounds like she's saying a large "book" too.
This sounds like it could lead to a large amount of confusion ;-;
