Prodigy vs. Prodigal
The words share a beginning but not a meaning. “Prodigy” names exceptional talent or an extraordinary example; “prodigal” concerns extravagant wastefulness and has a traditional returning-person noun sense.
Use “prodigy” as a noun for someone, especially a young person, with exceptional ability. Use “prodigal” mainly as an adjective for wasteful or extravagant use; it also has a noun sense for a person who leaves and later returns.
