What is even keel?

"Even keel" is an idiomatic expression that originates from nautical terminology. It is used to describe a ship that is perfectly balanced in the water, with its keel—the structural backbone along the base of the vessel—level and stable. When a ship is on an even keel, it sails smoothly without listing to one side or the other.

In a broader, more metaphorical sense, being "on an even keel" is used to describe a situation or a state of mind characterized by stability, balance, and calmness. It implies maintaining composure, steadiness, or emotional equilibrium, especially in challenging or turbulent circumstances. For instance, someone who manages stress effectively and remains calm under pressure might be said to be on an even keel. This expression is often used in both personal and professional contexts to highlight the importance of emotional stability and balance.
