The term 'Heavenly TOPPER' is a combination of two crossword solutions: HALO (4 letters) and TOPPER (7 letters). The word 'HALO' is derived from the Greek word 'HALOS' which means 'disk of light'. It is often used to refer to a circle of light that appears around the head of a holy figure in religious art. A 'TOPPER' is an item of clothing worn on the head, such as a hat or cap. Therefore, the term 'Heavenly TOPPER' could be used to describe a hat or cap with a HALO-like design.
