a secret handshake between meaning and noise, where the right key turns gibberish into gospel
means A cipher is a method of disguising a message by systematically swapping or scrambling its letters so only someone with the key can read it — or, separately, the number zero, or a person of no importance.
from It traces back to Arabic 'sifr,' meaning empty or zero, which traveled into Medieval Latin as 'cifra' and into French as 'cifre.' The zero was such a strange new idea to medieval Europe that the very word for 'nothing' came to mean anything mysterious and hard to decode — hence the leap from 'zero' to 'secret writing.' The same Arabic root, by a different road through Latin, also gave English 'zero' itself, so cipher and zero are long-lost siblings.
