An unleashed animal is one that's been set free from its cage or leash. This means it can roam around and do as it pleases.
When we talk about unleashing something or someone, we often mean releasing a lot of energy or power into action. For example, if you're on stage giving a passionate speech, your audience might say you've unleashed your words, meaning they really got through to them. We can also talk about unleashing our creativity or talents when we decide to show everyone what we're capable of.
Unleashed can be an adjective describing an animal that's been set free, but it's often used as a verb in other contexts.
To free from a leash, or as from a leash.
Example: He unleashed his dog in the park.
Not leashed; without a leash on it.
