Here are some examples of how it's used:
* Un libro regalado: A book given as a gift
* Un viaje regalado: A trip given as a gift
* Te regalo un abrazo: I give you a hug (literally: I give you a hug as a gift)
It can also be used to describe something that seems very easy or effortless:
* El examen fue regalado: The exam was ridiculously easy.
* El trabajo fue regalado: The job was a breeze.
In these cases, "regalado" is used figuratively to express the idea that something was given freely or easily, like a gift.
