"To buy a cheese sandwich"
Translation:A cumpăra un sandvici cu brânză
Brânză is the general term for any type of cheese obtained from milk, sometimes even from something else (brânză de soia = tofu), but Cașcaval is the name for a few types of hard cheese, usually yellow and obtained by boiling the milk, for example cheddar cheese.
Commonly the other way around. If you order a cheese sandwich you would say branza even though the branza you would get would be cașcaval
