A dangle is when something hangs loosely or flails about.
When we say that something dangles, it usually means it's hanging freely, without being supported. For example, a necklace might dangle from your neck if it isn't clasped properly. If you're cooking and forget to secure the handle of a pot, it can start to dangle precariously over the edge of the counter. You might even hear someone say that their pants are danging (meaning hanging down) because they need to be shortened. In some cases, people use the word 'dangle' when talking about something or someone that's on shaky ground - like a situation where you're trying not to get caught doing something you shouldn't be doing.
