## Latin
### Etymology

From Proto-Italic *ko(n/r)stā- (“rib”), of uncertain origin. Traditionally derived from Proto-Indo-European *kost-, and compared with Old Church Slavonic кость (kostĭ), Middle Persian [script needed] (kust), as well as *h₃ost- (“bone”), whence os (“bone”). However, de Vaan finds the connection with Slavic improbable and gives no etymology.
