Carolyn Kunin observes that 'the references to "K" and "S" seem to me to be another clue to the relation between the two characters - - in both senses of the word. "K" and "S" share a third common character, "C." In Cyrillic the sound /s/ is represented by "C" and in Latin the sound /k/ is represented by "C". Isn't it interesting?' and Jerry Friedman answers: "Yes, it's interesting that the letter C can sound like both K and S (and it looks like, and is etymologically related to,G). But at that level you can konnekt everything with everything elce."

Several postings ago, on a distinct issue ( "Pnin"), Stan Kelly-Bootle noted that: "VN's private 'audition coloree' gives 'p' as 'the unripe apple.' (Speak Memory, p 35).
According to him “The Russian 'sh' is fluffy-gray ("as old as the rushes of the Nile!") Ou en sommes-nous? VN spells his 'rainbow' kzspygv which he says is 'hardly pronounceable' ."

Joining the Kinbotean party enriched with these connections between colors, sounds and letters, I'd like to add a curiosity.

In Portuguese we find a verb that describes the rushing noise of wings, leaves and silk that suggests to me a distant connection to "butterflies" ( "Farfalhar" in Portuguese and similar-sounding to "farfalle" in Italian, now applied both to bow-tie shaped pasta and to the insect!).

It would have been amusing to translate: "o farfalhar das asas da borboleta" as "the butterfly-winged-rustle of butterfly wings".
