Is there a single term for “nieces and nephews”?
Is there a gender-neutral word for [aunts and uncles], parents' siblings?
The non-gender name for 'mother' is 'parent', for 'son' it is 'child'. But is there a non-gender word for 'uncle' or 'aunt'? Or is there no better definition than 'parent-sibling'?
If there is a word I would like to know the inverse as well, i.e. for 'nephew/niece'.
