Treen is an adjective that means made of wood.
It’s not a coincidence that the first three letters of our word of the day come to ‘tree.’ Tree is a word of Old English origin and by adding the suffix E-N, which means ‘made of,’ we get something made of the same substance as trees. Here’s an example:
The treen chest of drawers is just what I needed for this room. It seemed to me that something made of wood was a good addition with so many objects of steel around.
