The term 'SUNSET SETTING' can be broken down into two crossword solutions: HORIZON (7 letters) and WEST (4 letters). A HORIZON is the line at which the sky and the Earth's surface appear to meet, and is often used to refer to a distant view or vista. The word 'WEST' is used to describe the direction of the setting sun, as it moves from east to WEST across the sky. Together, these two words create a vivid image of a sunset setting, with the sun slowly sinking below the HORIZON in the WEST.
