Rucksack is also used for backpack in English.
Yep, rucksack is definitely acceptable here.
Please can we have rucksack?
Acceptable ghiozdan's: schoolbag, satchel, haversack, totebag, backpack, and pouch
I learn more and more every day
Glosbe says : Pouch or satchel
Could it also be valid translations?
I think sack would also be an acceptable translation for pungă.
