'uneconomic' originates from the prefix 'un-' meaning 'not' and the word 'economic,' which comes from the Greek word 'oikonomikos,' meaning 'household management.'

'economic' evolved from the Greek 'oikonomikos' to the Latin 'oeconomicus,' and eventually became the modern English word 'economic.' The prefix 'un-' was added to form 'uneconomic.'

Initially, 'economic' meant 'pertaining to household management,' but over time it evolved to mean 'related to the economy or profitability.' 'Uneconomic' thus means 'not related to profitability.'
