siblingcipher
/ˈsɪblɪŋˌsɪfə/nounVerified NewAlso in: Geschwisterchiffre (Deutsch) · hermanicifra (Español) · fratrichiffre (Français)
The private shorthand — single words, glances, half-phrases — through which siblings communicate entire paragraphs.
One word from childhood unlocks a shared verdict on a relative, a memory, or a smell. Siblingciphers are unlearnable by spouses and indecipherable to parents, which is a large part of their function. Decoding attempts are met with "you had to be there."
Etym. — sibling + cipher — the code that was never designed, only accumulated.
