'non-classicalist' originates from English, specifically formed by the prefix 'non-' + the noun 'classicalist', where 'non-' meant 'not' and 'classicalist' meant 'a supporter or practitioner of classical (tradition-based) approaches.'

'non-classicalist' was created in modern English by attaching the negative prefix 'non-' to 'classicalist' (itself formed from 'classical' + suffix '-ist'), producing a negated form meaning 'not a classicalist.'

Initially, the components meant 'not' + 'supporter of classical approaches'; over time the compound has been used to describe persons or approaches that deliberately distance themselves from classicalist conventions.
