noun
Refers to a situation, relationship, or problem that has become twisted, complicated, or difficult to resolve. Often used for interpersonal conflicts or procedural snarls.
話し合いがこじれて、会議が長引いた。
The discussion got tangled up, and the meeting dragged on.
二人の関
Their relationship has become so complicated that it can no longer be repaired.
Derived from the verb 拗れる (こじれる), which means 'to become twisted or complicated'. The noun form こじれ nominalizes that state. The kanji 拗 is rare and not commonly used for this word.
