Lots of interviews on YouTube suggest otherwise... https://m.youtube.com/watch?v=Ldpj_5JNFoA

> To avoid speaking like a child in public, Nabokov took great pains to prepare his every word. "Throughout my academic ascent in America from lean lecturer to Full Professor, I have never delivered to my audience one scrap of information not prepared in typescript beforehand and not held under my eyes on the bright-lit lectern."

> When it came to giving interviews, Nabokov was horrified by the notion of sitting back and having a casual chat with a reporter. "It has been tried at least twice in the old days," he writes, "and once a recording machine was present, and when the tape was rerun and I had finished laughing, I knew that never in my life would I repeat that sort of performance. Nowadays I take every precaution to ensure a dignified beat of the mandarin's fan. The interviewer's questions have to be sent to me in writing, answered by me in writing, and reproduced verbatim. Such are the three absolute conditions."

> So the excerpt above from a 1969 interview with the British journalist James Mossman should be understood as a carefully prepared performance.

Note how in the interview you posted, he frequently gets stuck on his prepared lines, resulting in sequences like or-or-or-or-or-or or the-the-the-the-the. (Yes, disfluencies are common in all speakers. But those disfluencies are not typical of English speakers, and reflect a different problem.)

If you already knew that Nabokov's interviews consisted entirely of remarks prepared in advance... why would you post that as a counterexample to "he wasn't able to speak perfect English"? That's the whole reason he prepared his responses.

Choirs frequently perform songs in foreign languages; nobody takes that as evidence that the members are able to speak those languages.

The reason Nabokov wouldn't speak in public without index cards was not ignorance but perfectionism. Index cards were his instrument—don't forget that he wrote his novels on those cards as well. For Nabokov, speaking in public without his index cards would be like not being properly dressed, or maybe dressed at all. Plenty of writers have that anxiety, including ones who never leave their native language.

You're still right, though. Nabokov's spoken English was nothing compared to his writing, and his genius would have made him painfully aware of that. The OP contains a partial version of this famous quote: "My private tragedy, which cannot, and indeed should not, be anybody's concern, is that I had to abandon my natural idiom, my untrammeled, rich, and infinitely docile Russian tongue for a second-rate brand of English..." The key word there is tragedy. To him his English was second-rate, and he would know.

That frames it elegantly, thanks.

Holy shit, that was dang
