Morphology

wood + vinegar

The compound 'wood vinegar' transparently denotes a vinegar-like liquid derived from wood: the head noun 'vinegar' combined with the modifier 'wood' signals the source/material. This source+product compounding pattern is common in English and other languages, so a B1 learner who knows 'wood' and 'vinegar' would readily infer the general meaning (even if they lack technical chemical details).

Etymology

The noun wood vinegar comes from old charcoal makers who collected a sour, reddish liquid that came from burned wood and smelled like vinegar. That's why today wood vinegar means the dark, sour liquid made when wood is heated to make charcoal and used in farming and industry.
