'cyanide-related' originates from 'cyanide,' which comes from the Greek word 'kyanos,' meaning 'dark blue,' and the suffix '-related,' indicating association or connection.

'Cyanide' evolved from the Greek 'kyanos' through French 'cyanure,' and 'related' comes from Latin 'relatus,' meaning 'brought back.'

Initially, 'cyanide' referred to a blue pigment, but it evolved to denote a chemical compound, and 'related' has maintained its meaning of association.
