Morphology

emeraldine = emerald (semi-transparent) = emerald + ine

Formally derived from 'emerald' + chemical/adjectival suffix '-ine', but the sense is a specialised chemical name for an oxidation state (named for its emerald-like colour), so the relation is clear in form but specialised in meaning.

Etymology

The word emeraldine comes from emerald, the green gemstone, plus the chemical ending -ine, so it literally means 'emerald-like'. So, scientists call the green form of a certain chemical emeraldine because of its green colour and its useful electrical properties.
