Pro Tip 1/3
Physical Objects
Use 'trash' for physical items you're throwing away, not for abstract concepts. Broken toys and old papers were all considered trash.
Pro Tip 2/3
Not Recycling
'Trash' often means items not recycled, so don't confuse with 'recyclables'. The glass bottles go in the recycling, not the trash.
Pro Tip 3/3
American Usage
'Trash' is most commonly used in American English; 'rubbish' is British. I need to take out the trash, while my British friend takes out the rubbish.
