camarada
/kamaˈɾada/ · B1 · noun · mf
companion
🤝 cámara (room) + -ada = roommates; English comrade comes from this word
Camarada first meant a group of soldiers sharing one cámara (room or barracks), and later anyone who shares your lot. English took it via French camarade, which became comrade. Its root is the same as the English word chamber.
