Producing, bearing, or generating fumes or smoke.
From Latin 'fumus' (smoke) + '-ferous' (bearing, producing, from ferre 'to carry'), creating a formal adjective describing anything that generates fumes.
The '-ferous' suffix is used in science to describe what things produce or carry (carboniferous, coniferous, odiferous)—it's a Latin inheritance that lets scientists create precise descriptive terms systematically.
