Context trumps content.

Ask the tree that lent the wood—that was its body.
For the troll living under the wooden planks spanning the river, this shade is home.
The three billy goats gruff, wanting to get to the greener grass on the other side, will use the bridge.
And for the tall boat journeying along the river, that assemblage of wood is simply in the way.

Purpose defines.
