妹妹 in 30 Seconds
- Means 'younger sister' in Chinese.
- Pronounced with a neutral second tone: mèi mei.
- Used for biological sisters and younger female cousins.
- Forms the basis of modern slang for young women.
The Chinese word 妹妹 (mèimei) is a fundamental kinship term that translates to 'younger sister'. In Chinese culture, distinguishing between older and younger siblings is not just a matter of vocabulary, but a reflection of traditional family hierarchies and respect. The character 妹 (mèi) is composed of the female radical 女 (nǚ) on the left and the phonetic component 未 (wèi) on the right. Historically, 未 meant 'not yet', suggesting a female who is 'not yet' fully grown, perfectly encapsulating the concept of a younger sister.
这是我的妹妹，她今年十岁。(This is my younger sister, she is ten years old this year.)
Understanding how to use 妹妹 goes beyond immediate family. It is also used affectionately for younger female cousins (表妹 biǎomèi or 堂妹 tángmèi) and even close younger female friends. This reflects the Chinese societal tendency to use family terms to build closeness and trust among non-relatives.
- Kinship Usage
- Used for blood-related younger female siblings.
我妹妹比我小三岁。(My younger sister is three years younger than me.)
In modern digital slang, the character 妹 has taken on new life. Terms like 软妹 (ruǎnmèi, soft/cute girl) or 迷妹 (mímèi, fangirl) are incredibly common. However, the core reduplicated form 妹妹 remains strictly 'younger sister' or a term of endearment for a younger female.
- Social Usage
- Used by older individuals to address younger females affectionately.
邻居家的妹妹很可爱。(The neighbor's younger sister is very cute.)
When learning Chinese, mastering family terms like 妹妹 is essential for basic introductions. You will often hear it paired with possessive pronouns, such as 我的妹妹 (my younger sister) or 他的妹妹 (his younger sister). In casual speech, the 的 (de) is often dropped, resulting in 我妹妹 or 他妹妹.
- Slang Derivations
- Forms the basis for modern internet slang describing young women.
她是一个典型的软妹子。(She is a typical soft/cute girl.)
To fully grasp the cultural weight of 妹妹, one must consider the impact of China's historical family planning policies. For many decades, having a 妹妹 was rare in urban areas, making the term sometimes aspirational or strictly applied to cousins. Today, with changing policies, the literal use of 妹妹 is becoming common again in nuclear families.
我一直想要一个妹妹。(I have always wanted a younger sister.)
Using 妹妹 (mèimei) correctly is quite straightforward for beginners, but there are nuances that advanced learners should master. The most basic structure is [Pronoun] + [妹妹], such as 我妹妹 (my younger sister). Notice the omission of the possessive particle 的 (de). While 我的妹妹 is grammatically correct, omitting 的 sounds much more natural and native-like when referring to close family members.
我妹妹喜欢吃苹果。(My younger sister likes to eat apples.)
When you have multiple younger sisters, you use ordinal numbers to differentiate them. The oldest of the younger sisters is 大妹妹 (dà mèimei) or simply 大妹 (dà mèi), the second is 二妹妹 (èr mèimei) or 二妹 (èr mèi), and the youngest is 小妹妹 (xiǎo mèimei) or 小妹 (xiǎo mèi).
- Multiple Sisters
- Use 大 (big), 二 (two), and 小 (small) to rank younger sisters.
我的小妹妹还在上幼儿园。(My youngest sister is still in kindergarten.)
Another common usage is as a direct address. You can call your younger sister simply '妹妹!'. However, it is also very common to call her by her given name, or a nickname (小名 xiǎomíng). Unlike older siblings (姐姐, 哥哥) where using the title is a sign of respect, you have more flexibility with younger siblings.
- Direct Address
- Can be used to call out to your sister directly.
妹妹，过来帮我一下！(Younger sister, come help me for a moment!)
In social contexts outside the family, older men or women might refer to a younger female friend or acquaintance as 妹妹 to show affection or protective care. However, men must be careful, as calling an unrelated woman 妹妹 can sometimes sound flirtatious or patronizing depending on the tone and context.
- Social Address
- Used affectionately for younger female friends, but carries nuances.
她就像我的亲妹妹一样。(She is just like my biological younger sister.)
You will also encounter the term 姐妹 (jiěmèi), which means 'sisters' in general. This is a combination of 姐姐 (older sister) and 妹妹 (younger sister). It is widely used to refer to female siblings or a close group of female friends (a 'sisterhood').
我们是好姐妹。(We are good sisters/close female friends.)
The word 妹妹 (mèimei) is ubiquitous in Chinese daily life, media, and literature. You will first encounter it in beginner language classrooms during lessons about family trees. It is an unavoidable core vocabulary word. Beyond the classroom, it is heard constantly in households, parks, and family gatherings across the Chinese-speaking world.
看，那是谁家的妹妹？(Look, whose younger sister is that?)
In Chinese television dramas, especially family dramas (家庭伦理剧) and idol dramas (偶像剧), the dynamic between siblings is a major plot device. The protective older brother (哥哥) and the cute, sometimes spoiled younger sister (妹妹) is a classic trope. You will hear characters shouting '妹妹!' in moments of high drama or affection.
- Pop Culture
- A common character archetype in Chinese media.
男主角非常疼爱他的妹妹。(The male lead deeply loves his younger sister.)
In literature, the concept of the younger sister often symbolizes innocence, vulnerability, or the burden of family responsibility. Classic novels like 'Dream of the Red Chamber' (红楼梦) feature complex webs of cousins who address each other as brothers and sisters, where terms like 林妹妹 (Lin mèimei) become iconic cultural references. Calling someone 'Lin meimei' today implies they are fragile, sentimental, and beautiful.
- Literature
- Used to denote innocence or specific literary archetypes.
别像林妹妹一样多愁善感。(Don't be as sentimental and fragile as Lin meimei.)
On the Chinese internet (Weibo, Xiaohongshu, Douyin), the character 妹 is highly productive in creating slang. You will see 迷妹 (mímèi) for a fan-girl obsessed with an idol, 辣妹 (làmèi) for a hot/trendy girl, and 软妹 (ruǎnmèi) for a girl with a soft, cute aesthetic. While these don't use the full reduplicated 妹妹, they stem from the same root concept of a young female.
- Internet Slang
- Forms the suffix for many modern terms describing young women.
她是一群偶像的迷妹。(She is a fangirl of a group of idols.)
You will also hear it in public spaces when adults speak to young children. A friendly adult might say to a little girl, '小妹妹, 你几岁了?' (Little sister, how old are you?). This is a polite and warm way to address a child whose name you do not know.
小妹妹，你的气球飞了。(Little sister, your balloon flew away.)
While 妹妹 (mèimei) is a beginner word, learners frequently make subtle mistakes regarding its pronunciation, grammatical usage, and cultural application. The most common error is pronunciation. The pinyin is mèi mei. The first syllable is a sharp, falling fourth tone, while the second syllable is a neutral tone. Many beginners pronounce both with a heavy fourth tone (mèi mèi), which sounds robotic and unnatural.
Correct: mèi mei (neutral second syllable). Incorrect: mèi mèi.
Another frequent mistake is overusing the possessive particle 的 (de). Beginners often say 我的妹妹 (wǒ de mèimei) in every context. While grammatically correct, native speakers almost always say 我妹妹 (wǒ mèimei) to indicate the close, inalienable relationship of family. Using 的 can sometimes make the relationship sound slightly distant or formal.
- Grammar Mistake
- Overusing '的' when referring to close family members.
Better: 我妹妹很高。 Instead of: 我的妹妹很高。
Culturally, learners sometimes confuse when to use 妹妹 versus 姐姐 (jiějie, older sister). In English, we often just say 'sister', but in Chinese, you must specify age relative to yourself. If you introduce your older sister as your 妹妹, it causes immediate confusion about family hierarchy.
- Vocabulary Confusion
- Mixing up older sister (姐姐) and younger sister (妹妹).
她是我姐姐，不是我妹妹。(She is my older sister, not my younger sister.)
Learners also make mistakes when trying to translate 'cousin'. In English, 'cousin' is gender-neutral and age-neutral. In Chinese, a younger female cousin is not just 妹妹, but 表妹 (biǎomèi, maternal side) or 堂妹 (tángmèi, paternal side sharing the same surname). Calling a cousin simply 妹妹 is acceptable in casual speech, but technically imprecise in formal introductions.
- Cousin Translation
- Failing to distinguish between biological sisters and cousins.
她是我的表妹。(She is my younger female cousin on my mother's side.)
Finally, a social mistake: male learners sometimes call female friends or colleagues 妹妹 to sound friendly. Depending on the age gap and relationship, this can come across as overly familiar, patronizing, or flirtatious. It is safer to use their name or a professional title until a very close friendship is established.
Avoid calling female colleagues 妹妹 in the workplace.
To build a robust vocabulary, it is important to understand words related to 妹妹 (mèimei). The most direct counterpart is 姐姐 (jiějie), which means older sister. Together, they form the compound word 姐妹 (jiěmèi), meaning sisters. This compound is used not only for biological sisters but also to describe strong bonds between female friends, similar to 'sisterhood' in English.
我们是亲姐妹。(We are biological sisters.)
When expanding to cousins, the vocabulary becomes more specific. 堂妹 (tángmèi) refers to a younger female cousin on your father's side who shares your family name (i.e., your father's brother's daughter). 表妹 (biǎomèi) refers to any other younger female cousin (e.g., your mother's sibling's daughter, or your father's sister's daughter).
- Cousins
- 堂妹 (tángmèi) and 表妹 (biǎomèi) specify the exact family branch.
我明天要去见我的表妹。(I am going to see my cousin tomorrow.)
For male siblings, the equivalents are 哥哥 (gēge, older brother) and 弟弟 (dìdi, younger brother). The collective term for brothers and sisters is 兄弟姐妹 (xiōngdì jiěmèi), which translates literally to 'older brother, younger brother, older sister, younger sister', but is used generally to mean 'siblings'.
- Siblings
- 兄弟姐妹 (xiōngdì jiěmèi) encompasses all brothers and sisters.
你有兄弟姐妹吗？(Do you have any siblings?)
In modern slang, the character 妹 (mèi) is combined with other words to describe types of young women. 软妹 (ruǎnmèi) means a soft, cute, and gentle girl. 辣妹 (làmèi) means a hot, trendy, or spicy girl. 萌妹 (méngmèi) means an adorably cute girl. These terms are highly popular on Chinese social media platforms.
- Slang
- 软妹, 辣妹, 萌妹 describe aesthetics and personalities.
她今天的打扮很像辣妹。(Her outfit today looks very much like a hot girl.)
Another related term is 妹夫 (mèifu), which means younger sister's husband (brother-in-law). Understanding these related terms helps you navigate the complex and highly specific Chinese family tree, which places a strong emphasis on age, gender, and maternal versus paternal lineage.
我的妹夫是一名医生。(My younger sister's husband is a doctor.)

Sentence Patterns
How to Use It
'妹妹' is standard and neutral. '令妹' is highly formal. '妹子' is casual and slightly slangy.
In Taiwan, '美眉' (měiméi) is sometimes used as a phonetic play on '妹妹' to mean a cute young girl. In Northern China, '老妹儿' (lǎomèir) is a common, affectionate way to address a younger female friend or service worker.
- Pronouncing both syllables with a full fourth tone (mèi mèi) instead of using the neutral tone for the second syllable (mèi mei).
- Using '我的妹妹' (wǒ de mèimei) instead of the more natural '我妹妹' (wǒ mèimei).
- Translating 'sister' as '妹妹' without checking if the sibling is actually younger or older (姐姐).
- Calling a cousin '妹妹' in a formal context instead of using the precise terms '表妹' or '堂妹'.
- Writing the right component as 末 (top stroke longer) instead of the correct 未 (top stroke shorter).
Tips
Master the Neutral Tone
The key to sounding native when saying '妹妹' is the neutral tone on the second syllable. Practice saying the first 'mèi' strongly with a falling pitch, and then just lightly tap the second 'mei'. Think of it like an echo. Don't force a tone onto the second character.
Drop the 'De'
Get into the habit of dropping '的' (de) when talking about your family. Say '我妹妹' instead of '我的妹妹'. This small change instantly makes your Chinese sound more fluent and natural. It shows you understand the concept of inalienable possession in Chinese grammar.
Watch the Horizontal Strokes
When writing the right side of 妹 (未), pay close attention to the two horizontal strokes. The top stroke MUST be shorter than the bottom stroke. If you make the top stroke longer, you write the character 末 (mò), which means 'end' and is incorrect.
Age Matters
In English, you can just say 'sister' without knowing who is older. In Chinese, you cannot. You must know if the female sibling is older (姐姐) or younger (妹妹). Always ask or observe before assigning the title, as getting it wrong disrupts the expected social hierarchy.
Addressing Little Girls
If you are an adult and need to get the attention of a little girl you don't know (for example, if she dropped her toy), calling out '小妹妹' (xiǎo mèimei) is the perfect, polite, and friendly way to do so. It is much better than saying 'hey you'.
Expand to Cousins
Don't stop at '妹妹'. Learn '表妹' (biǎomèi) and '堂妹' (tángmèi) early on. Because many Chinese people grew up without biological siblings, they are very close to their cousins. Knowing these terms helps you understand their family stories accurately.
Recognize '妹' Online
When browsing Chinese social media, look out for the character '妹' used as a suffix. Words like 萌妹 (méngmèi), 软妹 (ruǎnmèi), and 辣妹 (làmèi) are everywhere. Recognizing that '妹' implies 'young woman' will help you guess the meaning of new slang terms.
Listen for 'Jiemei'
You will often hear the word '姐妹' (jiěmèi). While it literally means 'older and younger sisters', it is frequently used to mean 'close female friends' or 'sisterhood'. If a woman talks about going shopping with her '姐妹', she likely means her best friends, not her biological siblings.
Be Careful with 'Meimei'
As a male learner, avoid calling adult female friends or colleagues '妹妹' unless you are very close and significantly older. It can easily be misinterpreted as patronizing or overly flirtatious. Stick to their names or professional titles to be safe.
The 'Not Yet' Mnemonic
To remember how to write 妹, remember the story of the character. The left side is a woman (女), and the right side means 'not yet' (未). A younger sister is a female who is 'not yet' fully grown. This etymological trick makes the character unforgettable.
Memorize It
Mnemonic
Imagine a WOMAN (女) who is NOT YET (未) fully grown. She is your younger sister (妹). Say it twice for affection: 妹妹 (mèimei).
Word Origin
The character 妹 is a phono-semantic compound. The left side 女 (nǚ) means 'woman' or 'female', indicating the gender. The right side 未 (wèi) acts as the phonetic component but also carries the semantic meaning of 'not yet'. Together, they historically represented a female who is 'not yet' fully grown, perfectly capturing the concept of a younger sister.
Cultural Context
'妹' is a cornerstone of internet slang for young women.
Using family terms for non-relatives builds social harmony.
Shifted the usage of sibling terms heavily onto cousins for a generation.
Older siblings have a duty of care (照顾) towards younger siblings.

Frequently Asked Questions
10 questionsYes, in casual conversation, it is very common to refer to a younger female cousin simply as '妹妹'. However, if you need to be precise, you should use '表妹' (biǎomèi) for maternal/cross-surname cousins and '堂妹' (tángmèi) for paternal/same-surname cousins. In formal introductions, specifying the exact relationship is preferred. But at home, calling her '妹妹' shows closeness. It reflects the Chinese cultural emphasis on extended family.
In Chinese grammar, the possessive particle '的' (de) is often omitted when referring to close, inalienable relationships, such as family members or close friends. Saying '我妹妹' (wǒ mèimei) sounds much more natural and intimate than '我的妹妹' (wǒ de mèimei). Using '的' can sometimes create a sense of distance. This rule applies to all immediate family terms like 爸爸, 妈妈, and 哥哥.
The second '妹' in '妹妹' is pronounced with a neutral tone (轻声 qīngshēng). This means it is pronounced lightly and quickly, without the sharp falling pitch of the fourth tone. The pinyin is written as 'mèi mei' or 'mèi me'. Pronouncing both characters with a full fourth tone (mèi mèi) sounds unnatural and robotic to native speakers.
'妹子' (mèizi) is a casual, colloquial term derived from '妹妹'. It generally means 'young woman' or 'girl'. It is widely used on the internet and in casual speech to refer to a female peer, often with a slightly affectionate or friendly undertone. However, it should be used carefully, as in some professional or formal contexts, it might be seen as too informal or slightly patronizing.
If you have more than one younger sister, you use ordinal numbers or size adjectives to differentiate them. The oldest of the younger sisters is called '大妹妹' (dà mèimei) or '大妹' (dà mèi). The second is '二妹妹' (èr mèimei). The youngest is usually called '小妹妹' (xiǎo mèimei) or '小妹' (xiǎo mèi). You can also just call them by their given names.
It depends on the context and age difference. An older adult can politely call a little girl '小妹妹' (xiǎo mèimei). However, a man calling an adult woman '妹妹' can sound overly familiar, flirtatious, or patronizing. It is generally safer to use '小姐' (xiǎojiě - miss, though this has regional nuances), '女士' (nǚshì - lady), or simply say '你好' (nǐ hǎo) if you don't know their name.
'妹' (mèi) means younger sister and has the female radical '女' on the left. '未' (wèi) is the right-hand component of '妹' and means 'not yet'. Visually, they are related, but '未' is not a standalone word for sister. Do not confuse '未' (top horizontal stroke is shorter) with '末' (mò, meaning end, where the top horizontal stroke is longer).
'林妹妹' (Lin meimei) refers to Lin Daiyu, a fictional character from the classic Chinese novel 'Dream of the Red Chamber' (红楼梦). She is famously beautiful, highly intelligent, but physically frail and emotionally sensitive. Today, calling someone '林妹妹' is a cultural idiom implying that they are delicate, sentimental, or easily upset.
The character for '妹妹' is exactly the same in both Simplified and Traditional Chinese. It is written as 妹妹. This makes it an easy word to learn regardless of which writing system you are focusing on.
'软妹' (ruǎnmèi) is modern Chinese internet slang. '软' means soft, and '妹' comes from 妹妹. It refers to a young woman who has a soft, gentle, cute, and traditionally feminine aesthetic and personality. It is part of a broader trend of using '妹' as a suffix to categorize different styles of young women, such as '辣妹' (làmèi - hot girl).
