'non-ceremonial' originates from the prefix 'non-' meaning 'not' and the word 'ceremonial' which comes from Latin 'caerimonia' meaning 'religious rite'.

'Ceremonial' evolved from the Latin 'caerimonia' through Old French 'ceremonial' and eventually became the modern English word 'ceremonial'. The prefix 'non-' was added to denote the absence of ceremony.

Initially, 'ceremonial' referred to religious rites, but over time it evolved to include any formal event. 'Non-ceremonial' specifically denotes the absence of such formality.
