Word Usage – What’s the Difference Between Lid and Cap?

word-usage

I searched for the difference between cap and lid: this post and also this post.

But I'm still confused.

My theory is this:

  1. the cap is a cover for a bottle

  2. the lid is a cover for a container which is not bottle

  3. the lid doesn't have a screw in it. If it has a screw, it is called a cap.

But then, a jar's cover doesn't fit into this classification. A jar has a screw in the cover but the cover is called a lid.

How do I distinguish a lid from a cap?

Your theory is mostly correct.

  1. the cap is a cover for a bottle

Yes

  1. the lid is a cover for a container which is not bottle

Yes

  1. the lid doesn't have a screw in it. If it has screw, it is called a cap.

No. Jars often have screw tops. That feature isn't relevant.

Coke cans

Soda cans usually have pop-tops, which is arguably a type of lid. It is not a cap.

Standard cans like pinto beans or mandarin oranges have a lid. The lid requires a can opener, or sometimes has a ring to pull it off. Manufacturers in the USA should strongly consider adding those rings more frequently because they are quite convenient.
