Morphology

mercurial = Mercury (semi-transparent) = mercury + ial

Formed from 'Mercury' but the adjectival meaning (eloquence, swiftness, thievishness) requires cultural/mythological knowledge of the god, so inference is not fully transparent to learners.

Etymology

Mercurial comes from the god Mercury, a quick and clever messenger who was also a trickster, so calling someone 'mercurial' suggests they are sharp, fast-thinking, or sometimes sly.
