Could you tell me what is the difference among trash, junk, garbage?

Garbage is what you put in the trash can/rubbish bin. Stuff from your kitchen, used tissues, etc. plus anything else you throw away. I don't see much of a difference between garbage and trash.

Junk, on the other hand, is "stuff." Some people will tell you that junk is just trash that you haven't thrown out yet. However, junk would NOT include kitchen waste or tissues, etc. It could be any

Even if there's no much difference between garbage and trash, which one do you use with can and bin? Garbage, I presume? You can't say trash can? Can one of these be British and another American?

In fact, I used "trash can" in my post above.

I think I use them interchangeably. There's a little trash can in my bathroom, and a larger garbage bin in my kitchen. There's a huge garbage can outside my garage that gets toted the curb on trash day. Any of these could mixed-and-matched.

There are some differences, I believe, in how it's use in BE, so we'll wait for Nona or Mr. P.

Often I would use them interchangeably, but I would be more likely to use "garbage" than "trash" for stuff that includes old food or other organic material. Trash looks bad, but garbage smells bad.

Sorry, teachers, I still did not get it. I saw "trash film" in the news. They used it to describ the film is very bad and make peopel feel very sucks. Can I say " junk film" ? Cause I know western people call KFC as " junk food" . Thanks

I thought you meant the nouns, not the adjectives.

Junk food is high in calories without a lot of nutritional value. It's a fixed phrase.

I've not heard of "trash films" before. If you say "Oh, that film was just trash" it means it wasn't any good.

They used it to describ the film is very bad and make peopel feel very sucks-->They
