'non-dimensional' originates from the prefix 'non-' meaning 'not' and the word 'dimension,' which comes from Latin 'dimensio,' meaning 'a measuring.'

'dimension' evolved from the Latin word 'dimensio' through Old French 'dimension' and eventually became the modern English word 'dimension.'

Initially, 'dimension' referred to 'a measuring,' but over time it evolved to mean 'a measurable extent of some kind, such as length, breadth, depth, or height.'
