The word obstinate describes a person who is stubborn and refuses to change their opinion or behavior. Antonyms for obstinate persons are those who are more open-minded, compliant, or flexible. Some possible antonyms include adaptable, cooperative, compliant, docile, meek, pliable, receptive, submissive, and tractable. These individuals are willing to listen to others' opinions, consider alternative ideas, and make necessary adjustments. They are not necessarily weak or indecisive; rather, they are practical and willing to compromise for the sake of harmony and progress. Unlike the obstinate, these individuals are not rigid in their thinking or inflexible in their actions but are willing to adapt to changes and challenges.
