Bong bóng isn't an actual ball, it's this soapbubble-thingy
Bong bóng is awesome
the classifier of balloon is "quả"
It can also be trái or just simply the generic cái.
It can't be "cái" for spherical things that has classifier is "quả". In some cases, "cái" before an object can indicate a different thing.
For example: quả bóng = the ball
cái bóng = the shadow
I'm not trying to be funny or cute with this; I'm actually trying to learn...
...so "cái bóng của quả bóng" would be 'the shadow of the (spherical) balloon'?
What if the balloon isn't spherical? A clown tied it into the shape of a sword, or a pony?
I’d be interested to know the answer to this too
