Morphology

polarographic = polarography (opaque) = polar + graph + o + ic

The word is a technical adjective built on the specialized noun 'polarography', and its meaning is not recoverable for an average learner from the component parts alone.

Etymology

Polarographic comes from polar ('pole', like North and South or electrical poles) and graph ('to write' or 'record', as in photograph or a chart). So polarographic relates to 'recording at the poles' and is used for methods that measure electric current to study chemicals.
