'noncyclical' originates from the prefix 'non-' meaning 'not' and the word 'cyclical' from the Greek 'kyklos' meaning 'circle'.

'Cyclical' evolved from the Greek word 'kyklikos', which transformed into the Latin 'cyclicus', and eventually became the modern English word 'cyclical'.

Initially, 'cyclical' meant 'pertaining to a circle', but over time it evolved to mean 'occurring in cycles'.
