Here are examples:
* "The car was unstuck after we pushed it." In this sentence, "unstuck" describes the state of the car.
* "The child's finger was unstuck from the toy." Again, "unstuck" describes the state of the finger.
However, "unstuck" can also be used as a past participle of the verb "unstuck."
For example:
* "I unstuck the lid from the jar." Here, "unstuck" is a past participle describing the action of the verb.
To determine whether "unstuck" is an adjective or past participle, you need to look at the context of the sentence.
