A person who works with timber, either by selling it or using it in construction, especially in mining.
The timberman carefully selected the best logs for the new building project.
Timberman is formed from "timber" (from Old English *timber*, meaning wood or building material) and "-man" (meaning a person who). A timberman is a person who works with or handles timber, typically in the context of logging or construction.
Think of a person who works with 'wood' ('timber') — that's what a timberman does.
