Other forms: danglings
Describing something as dangling means it's hanging down loosely, like the dangling silver charms on your grandmother's bracelet.
Dangling things are suspended or swinging freely, from your dangling legs that hang over the side of the dock with your toes just touching the water, to your cocker spaniel's silky, dangling ears. In grammar, a dangling modifier is a word or phrase that doesn't modify the word it's meant to; because the sentence is composed incorrectly, the modifier is left "dangling" awkwardly. In this sentence, the word "horrified" is dangling: "Horrified, the pop vocabulary quiz was apparently today."
