IPA: /ˈbɔːɡwʊd/

Wood that has been preserved in a wet, muddy area called a peat bog, often used for making artifacts or for decorative purposes.
The archaeologists discovered ancient tools made from bogwood in the peat bog.
Bogwood is formed from "bog" (from Old English *bōc*, meaning a wet, marshy area) and "wood" (from Old English *wudu*, meaning tree or timber). The term refers to wood that has been preserved in a bog, a wetland area.
Think of a 'wet, marshy area' ('bog') where 'wood' is found — that's why bogwood refers to wood preserved in such environments.
