The term 'precipice part' can be broken down into two crossword solutions: 'BRINK' (5 letters) and 'EDGE' (4 letters). Both words refer to the same concept, which is the steep or vertical face of a cliff or other high place. The BRINK is the very EDGE of the precipice, while the EDGE is the line where the precipice meets the ground. Both terms are often used to describe a dangerous situation, as one could easily fall off the EDGE of the precipice.
