siblings
Children sharing parents
Siblings are brothers and sisters—people who share at least one parent.
The term covers both sexes without specifying which: Do you have any siblings?
Full siblings share both parents; half-siblings share one.
The word often appears where "brothers and sisters" would sound clunky: sibling rivalry, sibling relationships.
