How it's used
Originating from ancient military strategy, this idiom describes a relationship where two parties are so closely linked that the survival of one depends entirely on the other. It is rarely used in casual daily chatter and carries a formal, literary weight. You will most often encounter it in political commentary, business analysis, or historical discussions.
Examples
The two companies are collaborating, they are truly interdependent.
Those two departments are interdependent, how can they be separated?
Related words
Common phrases
an interdependent relationship
Common mistake
Do not use this to describe casual friendships or simple cooperation, as it implies a deep, structural, and often existential level of mutual reliance.
