Description

Imagine setting sail on a stormy sea-that journey would be perilous. The word perilous describes something full of danger and risk. It is stronger than simply saying "dangerous" because it suggests a serious chance of harm or trouble. A mountain climber facing an avalanche or a knight battling a dragon both face perilous circumstances. You can also use it for a difficult choice if the wrong move could lead to major problems. Think of it as walking on a narrow edge-exciting, perhaps, but always close to disaster.
