Morphology

cyano + radical

The compound is a straightforward scientific formation: 'cyano' denotes the –CN (cyanide) group and 'radical' denotes a reactive chemical species, so 'cyano radical' literally describes a radical containing a cyano group. Although 'cyano' is specialist vocabulary and may be unfamiliar to many B1 learners, if a learner knows both constituents the meaning is directly derivable following standard chemical naming conventions.

Etymology

Cyano radical comes from cyano, a Greek word for 'dark blue', because early chemists linked this blue color (for example in Prussian blue) to compounds that contained this group. Radical here means a 'small reactive part' of a molecule, so the name points to the reactive -CN piece found in many compounds.
