妮 (nī) is a character that primarily means 'girl' in colloquial or dialectal use, and is commonly used as a phonetic element in female names (e.g., 妮妮, 安妮). In Taiwan, it is often pronounced with the second tone (ní). It is not a standalone word in formal contexts but appears in terms like 妮子 (nīzi, 'girl') and in transliterations.
