Etymology

From Latin illusorius 'deceptive', from illudere 'to mock, deceive' (ill- 'to mock' + ludere 'to play'). The form entered English via French illusoire / Italian illusorio, leading to illusory in English.

Mnemonic

Illusory = illusion-ary. Think: something that looks real but is just an illusion; it belongs to an illusion-ary realm.
