[ʃɛʁil]
* ʃ like the "sh" in "ship"
* ɛ like the "e" in "bed"
* ʁ like the "r" in "car" (rolled 'r' sound)
* il like the "eel" in "feel"
However, it's important to note that this pronunciation would sound very foreign to French speakers. They might not understand what name you are referring to.
It's best to choose a French name that is similar in meaning or sound to Cheryl, such as:
* Chloé (pronounced [klo.e])
* Charline (pronounced [ʃaʁ.lin])
* Coralie (pronounced [kɔ.ʁa.li])
