The term 'circle overhead' can be broken down into two crossword solutions: HALO (4 letters) and ELS (3 letters). HALO is a word used to describe a circle of light or a ring of light that appears around the head of a saint or holy figure in art. It is also used to describe a circle of light that appears around the sun or moon. ELS stands for Equidistant Letter Sequence, which is a type of pattern found in the Hebrew Bible. This pattern is created by selecting certain letters from the text that are equally spaced apart.
