chamber: [13] The ultimate source of chamber is Greek kamárā ‘something with an arched cover, room with a vaulted roof’. This passed into Latin as camara or camera (source of English camera), and in Old French became transformed into chambre, the immediate source of the English word. Related forms in English include comrade (from Spanish camarada), originally ‘someone sharing a room’; chamberlain [13], which was originally coined in the West Germanic language of the Franks as *kamerling using the diminutive suffix -ling, and came into English via Old French chamberlenc; and chimney.
