When Ada recites her revised monologue of Shakespeare’s King Lear, Greg Erminin exclaims ‘Oh, that’s good:’

‘Et pourtant,’ said the sound-sensitive governess, wincing, ‘I read to her twice Ségur’s adaptation in fable form of Shakespeare’s play about the wicked usurer.’

‘She also knows my revised monologue of his mad king,’ said Ada:

In VN’s novel Ada (1969) the element that destroys Demon Veen (Van’s and Ada’s father who perishes in a mysterious airplane disaster above the Pacific) is air:

Numbers and rows and series — the nightmare and malediction harrowing pure thought and pure time — seemed bent on mechanizing his mind. Three elements, fire, water, and air, destroyed, in that sequence, Marina, Lucette, and Demon. Terra waited. (3.1)

According to Miss Cleft (the headmistress of Ada’s school for girls), a thorn is always close to a bud:

Describing the difference between Terra and Antiterra (aka Demonia, Earth’s twin planet on which Ada is set), Van Veen (the narrator and main character in VN’s novel Ada, 1969) mentions the deepest thinkers, the purest philosophers, Paar of Chose and Zapater of Aardvark:

In VN’s novel Ada (1969) Lucette’s note (written after the dinner in ‘Ursus’ and debauch à trois in Van’s Manhattan flat) to Van and Ada ends in the words Pour Elle (Fr. “for her”):

Describing his father’s death in a mysterious airplane disaster, Van Veen (the narrator and main character in VN’s novel Ada, 1969) mentions a maussade Lebanese beauty of fifteen sultry summers:

Describing his sexual dreams, Van Veen (the narrator and main character in VN’s novel Ada, 1969) mentions a dream in which Ada and Lucette (Van’s and Ada’s half-sister) slake their thirst in the pool of his blood:

According to Ada, at Marina’s funeral Demon Veen (in VN’s novel Ada, 1969, Van’s and Ada’s father) told her that he would not cheat the poor grubs:

‘My upper-lip space feels indecently naked.’ (He had shaved his mustache off with howls of pain in her presence). ‘And I cannot keep sucking in my belly all the time.’

Describing Ada’s amorous life, Van Veen (the narrator and main character in VN’s novel Ada, 1969) repeats the French word ailleurs (elsewhere) three times:

After Van Veen (the narrator and main character in VN’s novel Ada, 1969) possessed her for the first time, Cordula de Prey mentions un petit enfantôme:

Cordula told Edmond: ‘Arrêtez près de what’s-it-called, yes, Albion, le store pour messieurs, in Luga’; and as peeved Van remonstrated: ‘You can’t go back to civilization in pajamas,’ she said firmly. ‘I shall buy you some clothes, while Edmond has a mug of coffee.’
