Etymology
The word 'ricin' is a modern scientific formation, coined in the late 19th century. It is derived directly from the Latin botanical name for the castor oil plant, 'Ricinus communis'. The suffix '-in', a standard in biochemical nomenclature, is appended to indicate it is a proteinaceous substance derived from that source. Thus, the term's literal construction transparently denotes "a chemical substance from the castor bean plant," which aligns perfectly with its modern definition as a toxic protein extracted from that seed.
Analysis
'ric' is from Latin 'ricinus', meaning 'castor oil plant'. 'in' is a scientific suffix of Latin origin used to form names of proteins, alkaloids, and other chemical substances.
