pneumonoconiosis (English)

Where does "pneumonoconiosis" come from?

The medical term 'pneumonoconiosis' entered English as a borrowing from German 'Pneumonokoniosis', introduced around 1867[1]. The German compound was constructed from 'pneumono-', meaning 'lung', the Ancient Greek word 'kónis', meaning 'dust', and the suffix '-osis', denoting a disease[1]. In its earliest English appearance in 1878, the term was also patterned after the French form 'pneumonokoniose'[1]. Ultimately, the Greek component traces back to the Proto-Indo-European root '*ken-', signifying 'dust' or 'ashes'[2].
