侄女

noun

niece (daughter of one's brother or other male relative of the same generation); also used for a friend's daughter

In Chinese kinship terms, 侄女 specifically refers to the daughter of one's brother (as opposed to 外甥女, the daughter of one's sister). The term can also be extended to refer to a friend's daughter. In northern dialects, it is commonly pronounced with the 'r' suffix as 侄女儿 (zhí nǚr).
