Supplication (also known as petitioning) is the most common form of prayer, wherein a person asks a supernatural deity to provide something, either for the person who is praying or for someone else on whose behalf a prayer of supplication is being made, also known as intercession. The concept of supplication is also perfectly at home in a secular context. The supplicant may also be described as a suppliant but the former word is more commonly used.
