I thought ga was like a more emphasis I really do not know like..

watashi wa tabetai desu - I want to eat
and

watashi wa ringo ga tabetai desu - I want to eat 'apples' (more specifically)

watashi wa ringo wo tabetai desu - I want to eat apples (but can also eat somethign else as well)?

Thats what I thought at least.

Can someoen confirm/deny this? I'm really am lost lol.
