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.

  • Is it a mathematically graphical/topological tree or an actual biological tree? – Blessed Geek May 8 '15 at 11:10

    The difficulty I'm having is no real-world tree can exist that is without an exterior, or bark? Can you give another example? – user98990 May 8 '15 at 11:16

    Any core still has an outside. A core without an outside is a geometrical point, i.e. a purely theoretical concept devoid of any body. – RegDwigнt May 8 '15 at 11:18
  • interiority noun: the quality of being interior or inward. • inner character or nature; subjectivity. – user98990 May 8 '15 at 11:21

    What we see, we perceive to be the exterior. If you peel a couple of layers off an onion, what you've got is some onion peels and the rest of the, wait for it, onion. – Tushar Raj May 8 '15 at 11:27

I nominate skeleton.

The supporting framework, basic structure, or essential part of something:

the concrete skeleton of an unfinished building (No exterior)

the skeleton of a report (No exterior)

In the case of a tree, I might use the term denuded.

denuded adj
without the natural or usual covering;


By the way, this is not really an antonym of hollow, because what you're looking for is not really an antonym, per se. It's more like a mirrored state, or a complementary state. The antonym of hollow would be filled or full or any of several others. The state you describe is something else again.

You can say that you have the core or heart of something.

  1. To remove (a layer of bark or skin, for example) in flakes or scales; peel.
  2. To cast off in scales, flakes, or splinters.

...if the exterior has been removed by some process.

    What does this have to do with not being hollow? – Drew Jul 19 '15 at 22:34
  • Nothing, but it seems that 'not hollow' isn't exactly what OP is looking for. – user129828 Jul 20 '15 at 12:17
  • Clever approach, user! But it doesn't conjure the image in my mind. – ScotM Jul 20 '15 at 20:49

I guess the word you are looking for is marrow. However, I don't know if it suits the example you gave. I'd rather say naked or bare.

  • Could you add a definition of that as a adjective, or an example? It's along the lines of what I'm looking for in terms of the innards of a bone, but on searching I can only find descriptions of the vegetable. – Mike.C.Ford May 8 '15 at 11:48
  • The problem is that "marrow" is not an adjective, it’s a noun. It means the inmost or essential part. "bone marrow" also means the soft fatty vascular tissue in the cavities of bones: a major site of blood cell production. Example: Pierce to the marrow of a problem. I guess "marrowy" is the adjective form of it, but I don't know if it still has the same meaning. – Mazen Draou May 8 '15 at 13:52

I'd probably go with skinned, the past participle of "to skin", which is defined by oxforddictionaries.com as to "remove the skin from (an animal or a fruit or vegetable)". Similar words might be "stripped", or, less pleasantly, "flayed".
