Answer:
As a stone inside a tree, I’ll help your words outlive thee. But if you push me as I stand, the more I move the less I am.
Though not a plant I have leaves. though not a beast I have spine. Though many wouldn't need me I am more valuable than wine.
I get wet when drying. I get dirty when wiping.
In all the world, none can compare, I am a tiny weaver; my deadly cloth so silky and fair. What am I?
I hatch without food
I am rarely touched but often held. If you are smart you'll use me well. What am I?
