The term SIGN OF SANCTITY is composed of two crossword solutions, HALO (4 letters) and AUREOLE (7 letters). A HALO is a circle of light that appears around the head of a holy figure in religious art. It is often used to signify holiness, divine power, or a saintly person. An AUREOLE is a similar concept, but it is usually depicted as a larger, more elaborate circle of light. It is often used to represent the presence of God or a divine being. Both of these symbols are signs of sanctity and are used to represent holiness and divine power.
