Five ranks are used to measure how important or valuable something is compared to other things. The five ranks, from the highest value to lowest, are: first, second, third, fourth, and fifth.
First is the highest rank and it means the most important or valuable. Second is the second highest rank and it means something is important or valuable but not as much as first. Third is the third highest rank and it means something is important or valuable but not as much as first or second. Fourth is the fourth highest rank and it means something is important or valuable but not as much as first, second, or third. Fifth is the lowest rank and it means something is not very important or valuable compared to the other ranks.
