Morphology

ferrocyanic + acid

This is a regular modifier+noun compound: 'ferrocyanic' (relating to iron/cyanide chemistry) + 'acid' denotes an acid derived from that chemical group. Although the term is technical, its meaning is compositionally predictable for a learner who knows the modifier and 'acid' (and the roots 'ferro-' and 'cyan-'), so the expression is transparently built from its parts.

Etymology

Ferrocyanic acid comes from two parts, ferro meaning 'iron' and cyanic from 'cyan', a dark blue color from a dye used long ago. Chemists named the acid made from iron-containing cyanide salts ferrocyanic acid, so the word tells you it is an acid from those blue iron salts even though the acid itself is unstable.
