Here are some examples of words that come from this root:
* Cantata: A piece of music for voices, especially one with a religious text.
* Incantation: A chant or magical formula used to invoke a spirit.
* Enchant: To charm or bewitch someone.
* Canticle: A hymn or song, especially one from the Bible.
* Chant: To sing in a repetitive, monotone way.
Interestingly, the word "cant" can also be used as a noun to mean "hypocritical or insincere speech". This meaning is related to the original meaning of "sing" because it suggests a type of performance that is not genuine.
