'outmoded' originates from the prefix 'out-' meaning 'beyond' and the word 'mode,' which comes from Latin 'modus' meaning 'measure, manner, or way.'

'outmoded' evolved from the combination of 'out-' and 'mode,' which was used in Middle English to describe something beyond the current fashion or style.

Initially, it meant 'beyond the current mode or fashion,' and this meaning has largely remained the same in modern usage.
