sis
Casual female relative
Sis is an informal term of address for a sister, or for any woman or girl you feel close to: Hey sis, can I borrow your car?
Among women, sis functions as a term of solidarity or friendly address, even between strangers: You dropped your phone, sis.
It carries warmth and familiarity without the full formality of "sister."
