sibs
Brothers and sisters
Sibs is an informal plural of sibling—brothers and sisters: I have three sibs, all younger than me.
The word appears in casual speech and writing where "siblings" feels too formal.
In scientific contexts, particularly genetics and animal behavior, sibs refers to individuals sharing common parents.
