chorus

The word 'chorus' originates from the Latin chorus, which was borrowed directly from the Ancient Greek khoros (χορός). In ancient Greece, a khoros was a company of dancers and singers who performed in religious festivals and theatrical dramas, integral to the storytelling. The Romans adopted the term for similar theatrical and musical ensembles. Over time, as the word passed into English via Latin, its meaning expanded from a specific theatrical troupe to encompass any organized group of singers, the refrain of a song (which is sung by many voices), and finally, any simultaneous utterance by a crowd.

Structure: chor (dance, choir) + us (noun suffix) - chor: From Greek khoros, meaning a band of dancers and singers, a dance, or a dancing ground. It functions as the core root conveying the concept of a collective performing group. - us: A Latin noun suffix used to form nouns, often from Greek loanwords. It functions as a nominalizing ending in English.
