the brother of someone’s mother or father, or the husband of someone’s aunt
I have lots of uncles and aunts.
We invited my Uncle Steve over.
The family gathered to celebrate the birthday of their beloved uncle.
An uncle can be a source of guidance and support for nieces and nephews.
The children eagerly awaited their uncle's stories and playful antics.
In some cultures, the term "uncle" is used to address close family friends or mentors.
