What does 妹妹 mean?

妹妹 (mèimei) means 'younger sister.'

Chinese kinship terms encode age relative to the speaker, so there is no general word for 'sister' — you must specify 妹妹 (younger) or 姐姐 (jiějie, older). The second syllable is a neutral tone (mèimei, not mèimèi), which is typical of family terms (爸爸, 妈妈, 哥哥). Possession usually drops the particle for close family: 我妹妹 ('my younger sister'), 他妹妹 ('his younger sister').

妹妹 is also used informally to address or refer to a young girl who is not actually one's sister — for example, a stranger calling out to a younger woman in a friendly way (小妹妹 'little girl,' 美女妹妹 in playful contexts). The single-character form (mèi) appears in compounds like 姐妹 (jiěmèi, 'sisters') and 表妹 (biǎomèi, 'younger female cousin').

Note: 妹妹 is the everyday word for one's younger sister. The second syllable is neutral tone (mèimei). Older sister is 姐姐 (jiějie) — Chinese kinship terms always specify whether the sibling is older or younger.
