Other forms: exigencies
Think of a mix of excitement and emergency, and you have exigency, a sudden, urgent crisis. The very word conjures up danger and intrigue that demand a cool head and an immediate effort at a solution.
Exigency derives from the Latin noun exigentia, which means "urgency" and comes from the verb exigere, meaning "to demand or require." An emergency situation, or exigency, is urgent and demands immediate action. Our lives are filled with exigencies, both large and small, from a child stuck in a tree to lightning striking your house to catastrophic river flooding. Each is an exigency — it's all a matter of perspective.
