Question

is it correct English to say that I will see again sister . to the sister who passed away

Answer 1

The phrase "I will see again sister" is not grammatically correct. A more appropriate and grammatically correct expression could be "I will see my sister again" or "I will see you again, sister," if you are addressing her directly in a heartfelt manner. If you are referring to the idea of reuniting in the future, it might also be meaningful to say something like "I look forward to seeing my sister again one day."
