Usage

What does timber mean? Timber refers to wood used for building materials. Timber can be used to refer to wood at different stages of processing. Sometimes, it refers to the trees in a wooded area that will be cut for use. Other times, it means trees that have already been cut down but not yet processed into planks and other forms to build with. And other times it refers to the wood after it has been processed (a more common word for this is lumber). Timber is most commonly used as a mass noun, meaning it is a singular noun that refers to multiple things and does not get pluralized. Example: Those trucks are bringing freshly cut timber to the mill.

Etymology

Origin of timber

First recorded before 900; Middle English, Old English: originally, “house, building material, wood, trees”; cognate with German Zimmer “room,” Old Norse timbr “timber”; akin to Gothic timrjan “to build,” Greek démein “to build,” dómos “house,” Latin domus “house,” Slavic ( Polish ) dom, “house, home,” Sanskrit dáma- “house, building”; dome

Explanation

Timber! That's the call of warning you hear before a tree falls. That's because those lumberjacks are going to use the tree to make timber, otherwise known as "lumber" or the wood used for construction. Timber can actually be the trees used to make or build something, or the wood that comes from those trees, which you could also call "lumber." You might think that when a pirate yells "shiver me timbers!" he's referring to his wooden peg leg. But the timbers he's talking about are actually the boards and planks used to build the frame of a ship.
