'ascarides' originates from New Latin, specifically the word 'Ascaris', which ultimately comes from Greek 'askaris' where 'askaris' meant 'intestinal worm'.

'ascarides' changed from the New Latin word 'Ascaris' (from Greek 'askaris') and the English noun 'ascarid', and eventually became the modern English plural forms 'ascarids' and 'ascarides'.

Initially it meant 'intestinal worm' in Greek; over time it became the scientific term for specific parasitic roundworms (Ascaris and related nematodes) used in modern biology and medicine.
