stubborn

This word carries a heavy weight of resistance. When applied to people, it often suggests a willful refusal to compromise, leaning toward a negative connotation of being unreasonable or pig-headed. However, in specific contexts like pursuing a difficult goal, it can be framed as a form of grit or tenacity. When applied to objects or conditions, the word evokes a sense of frustration. It describes something that defies effort, such as a rusted bolt or a persistent cough, implying that the object is actively fighting against the attempt to fix or change it.
