droopy
Hanging down loosely, like tired or sagging parts.
Droopy means hanging down loosely or sagging in a tired, limp way. When flowers don't get enough water, their petals and stems become droopy. A dog with droopy ears, like a basset hound or beagle, has ears that hang down instead of standing up straight.
People can look droopy too. After staying up too late, you might see droopy eyelids in the mirror. When someone feels sad or exhausted, their whole posture might become droopy, with shoulders slumping and head tilting down. Picture a balloon three days after a birthday party, no longer full and round but sagging and wrinkled. That's droopy.
The word captures that specific quality of something that should be firm or upright but has lost its energy or support. A droopy houseplant perks up after watering, and a droopy person perks up after rest. The word suggests something temporary, a state that can be fixed rather than a permanent condition.
