1 the brother of someone’s mother or father, or the husband of someone’s aunt:
We went back to Ireland for my uncle's burial.
I struck up an interesting conversation with your uncle.
Four uncles and three aunts had virtually no contact with nieces or nephews and rarely saw any of them.
Marriage to the niece, or maternal uncle's daughter was permitted and was often considered the ideal marriage.
Thus disgruntled children could always turn to uncles.
