Morphology

plumbous = plumb (opaque) = plumb + ous

The adjective is a specialized chemical term formed from the Latin stem for lead plus '-ous'; ordinary knowledge of 'plumb' (vertical/depth) will not allow learners to infer the chemistry meaning.

Etymology

Plumbous comes from the Latin plumbum, which means 'lead'. You can see the same root in plumber and plumb, the old word for a heavy lead weight on a line, so plumbous means 'containing lead' and is used in chemistry for lead that has a two-unit positive charge.
