obstinate

What does "obstinate" mean?
Obstinate describes someone who stubbornly refuses to change their opinion or chosen course of action, despite attempts to persuade them to do otherwise. It carries a strong mental image of someone digging their heels into the ground, immovable and fixed in their position, often to the point of being unreasonable. While "stubborn" is a neutral or slightly negative term, "obstinate" carries a more formal and critical weight. It is typically used when someone’s refusal to budge is seen as particularly difficult or obstructive. It is a common collocation to be "obstinate about" a specific policy or "obstinate in" one's refusal to cooperate.
