Origin

Late Middle English: from Latin evaporat- 'changed into vapour', from the verb evaporare, from e- (variant of ex-) 'out of' + vapor 'steam, vapour'.

  • vapour from Late Middle English:

    This comes from Latin vapor ‘steam, heat’. Evaporate (Late Middle English) comes from the Latin for ‘to change into vapour’, evaporare. Latin Vapidus ‘savourless’, source of vapid (mid 17th century), is probably related. See also hysteria
