protract
To make something last too long and feel dragged out.
To protract means to make something last longer than necessary, usually in a way that becomes tiresome or frustrating. When a simple decision gets protracted into weeks of endless discussion, what should have taken an afternoon stretches into something that feels like it will never end.
You see protracted situations in many places. A protracted argument is one that drags on and on, with neither side willing to compromise or move forward. A protracted illness lasts much longer than expected, wearing down the patient and their family. In history, a protracted war is one that continues for years beyond what anyone anticipated, draining resources and resolve.
When something becomes protracted, it loses the sharpness and energy it might have had at the start. A protracted farewell at the end of a party, with everyone saying goodbye multiple times, stops being sweet and starts feeling awkward.
Notice that protracted almost always has a negative feeling. We don't say a wonderful vacation was protracted. We use it when delay itself becomes a problem, when something that should move along efficiently gets stuck in slow motion.
