Here are some options:
* 兄弟 (きょうだい - kyōdai): This is the most common and general term for siblings, encompassing both brothers and sisters.
* 兄 (あに - ani): Older brother.
* 弟 (おとうと - otōto): Younger brother.
* 姉 (あね - ane): Older sister.
* 妹 (いもうと - imōto): Younger sister.
Therefore, to say "my siblings," you would use a phrase like:
* 私の兄弟 (わたしのきょうだい - watashi no kyōdai): My siblings (brothers and sisters)
You would need to use a combination of the individual words for brothers and sisters if you want to be more specific, for instance "my brothers and sisters."
