'non-ritualistic' is formed by adding the prefix 'non-' (meaning 'not') to 'ritualistic', which comes from 'ritual'. 'Ritual' originates from Latin, specifically the word 'ritualis', where 'ritus' meant 'rite' or 'ceremony'.

'Ritual' came from the Latin word 'ritualis', which became 'ritual' in English. 'Ritualistic' was formed from 'ritual', and 'non-ritualistic' was later created by adding 'non-'.

Initially, 'ritual' referred to religious or formal ceremonies, and 'ritualistic' described things related to such ceremonies. 'Non-ritualistic' thus came to mean 'not related to rituals or ceremonies'.
