Semantic evolution

In Columella it meant the unison of instruments, literally a breathing together.[6][7] In Cicero it meant agreement, harmony, concord, as cōnspīrātiō bonōrum omnium “the union of all good men”, and a combination for a hostile or unlawful end, a conspiracy, and its members.[2][7]

In Ecclesiastical Latin it meant agreement, common opinion, cooperation, conspiracy.[8] British Medieval Latin used it for a conspiracy and for champerty.[9] It survives in Italian cospirazione and French conspiration, and Anglo-French conspiracie gave English conspiracy in the mid-14th century.[1][4]
