Forms
illūdō (present infinitive illūdere, perfect active illūsī, supine illūsum); third conjugation[1] It is also spelled inlūdō.[2][3][4] Gellius has the first-conjugation form illudiābant.[3]
Etymology
It is from Latin in- + lūdō (“to play”).[2][1][4] De Vaan derives ⟨lūdō⟩ from Proto-Italic *loid-e/o- (“to play”) and Proto-Indo-European *loid- (“to let go frequently, play”), cognate with Lithuanian léisti (“to let”) and Middle Irish laídid (“impels”).[5]
Earliest recorded meaning
The OLD's earliest examples are from Terence, of making fun of someone: “you mock me quite arrogantly enough”.[2][6]
Semantic evolution
It is to make game of, mock, and to fool or dupe: in Cicero someone thought he was being tricked, or that the man himself was wrong.[2] Terence also uses it of trifling something away: in trying to oblige, a father nearly “fooled away” his daughter's life.[2] Virgil uses it of garments decked out with gold, and Silius Italicus and Tacitus of sexual abuse.[2] Lewis and Short call the sense “to ruin, destroy in sport” chiefly poetic and post-Augustan.[3][1]
Church Latin has it for mock, delude, deceive, deride.[7] English illude (early 15th century), “to trick, deceive”, is from it.[8]
