mirage (English)

Where does "mirage" come from?

The English noun 'mirage' entered the language around 1812 as an unadapted borrowing from French 'mirage'[1]. The French term itself combines the verb 'mirer' with the suffix '-age'[2]. The verb traces back through Old French 'mirer' to the Latin verb 'mīrārī', meaning 'marvel at'[3][5]. This Latin word originates from 'mīrus', meaning 'remarkable' or 'astonishing'[4][6]. Pushing back even further into antiquity, these roots descend from the Proto-Indo-European root '*(s)mey-', which meant 'to laugh' or 'to be glad'[4][6].
