Morphology

methenamine = amine (opaque) = methen + amine

The combining form 'methen-' is not a standalone English morpheme and the medical/antibacterial meaning of 'methenamine' is not predictable from 'amine' for average learners.

Etymology

The word methenamine is built from parts that tell you what it is: meth- (as in methane) points to a very small carbon part, and -amine (as in amino) means it has a nitrogen group. So the name fits: it describes a small nitrogen chemical used as a medicine to help prevent bladder infections.
