What is wood called when it is cut from a tree?

Wood that is cut from a tree is commonly referred to as "lumber" or "timber," depending on its intended use and regional terminology. In general, "timber" often refers to larger, unprocessed wood, while "lumber" usually denotes wood that has been processed and milled for construction or manufacturing purposes. The term "logs" is also used to describe the raw, uncut sections of a tree trunk before further processing.
