I'm looking for an adjective that describes an object that, rather than is just the outside, is instead just the inside.
Searching for antonyms of hollow, I have only found the word solid, which suggests both the inside and outside of an object.
I really need a way to describe something as being just the inside of something.
I can only think of words like core or heart to describe what I'm looking for, but those are nouns.
When a tree has only its exterior, the tree is hollow. It is a hollow tree.
When a tree has only its interior, the tree is _____. It is a _____ tree.
Perhaps tree was a bad example, it was the only object I could think of at the time that made sense to be a hollow object. Any object where that description could apply is a reasonable substitute, it does not have to be specifically about a tree.
