Korean Family Vocabulary Guide: List of Korean Terms for Family Members

Learning how to talk about your family in Korean opens up some of the most common conversations you'll have. Whether you're introducing yourself, chatting with Korean friends, or trying to follow a K-drama without subtitles, family vocabulary comes up constantly. The tricky part? Korean has way more specific terms than English does. You can't just say "brother" or "sister" and call it a day. Korean family vocabulary changes based on gender, age, formality, and even which side of the family someone's on. Here's everything you need to know when learning Korean.

Why Korean family terms are more complex than English

English keeps family vocabulary pretty simple. You've got mom, dad, brother, sister, and you're basically set for immediate family. Korean? Completely different story.

Korean family terms split based on several factors.

This complexity reflects Korean culture pretty deeply. Age hierarchy and respect levels are built right into the language. You can't talk about family members without acknowledging where everyone sits in the family structure.

Immediate family: Parents

Let's start with the most basic terms. For parents, you've got formal and casual options.

Siblings: Where it gets specific

Here's where Korean family vocabulary really shows its complexity. The word you use for siblings depends entirely on your gender and whether the sibling is older or younger than you.

For older siblings, you have four different terms:

For younger siblings, things simplify. 동생 (dongsaeng) works for both genders and means "younger sibling." You can specify gender by saying 남동생 (namdongsaeng) for younger brother or 여동생 (yeodongsaeng) for younger sister, but plain 동생 works fine in most conversations.

The Korean language doesn't require you to specify whether you're talking about older or younger siblings in the same way. Age hierarchy matters more for older siblings, which is why they get specific terms.

Grandparents and the paternal vs maternal side of the family

Korean makes a clear distinction between your father's side and your mother's side of the family. This matters especially for grandparents.

For paternal grandparents (father's parents):

For maternal grandparents (mother's parents):

That 외 (oe) prefix specifically marks the maternal side. Pretty much any maternal relative gets this prefix to distinguish them from the paternal side.

This distinction isn't just linguistic. Historically, Korean culture placed more importance on the paternal family line, and the language reflects that hierarchy. These days, the practical importance has faded, but the vocabulary remains.

Extended family members in Korean

Korean family vocabulary extends way beyond the immediate family. You've got specific terms for family members such as aunts, uncles, and cousins, depending on which side they're from.

For paternal uncles:

For maternal uncles:

Aunts follow similar patterns:

Cousins generally use 사촌 (sachon), though you might hear more specific terms in traditional families.

The level of detail here can feel overwhelming at first. Most Korean learners focus on immediate family terms first and pick up extended family vocabulary gradually as they need it.

In-law family terms in Korean for married couples

Marriage brings a whole new set of Korean family vocabulary into play. In-law terms differ based on whose family you're talking about and, again, gender matters.

For a wife, her husband's parents are:

For a husband, his wife's parents are:

Siblings-in-law get specific terms too:

For your own spouse, you'd use 남편 (nampyeon) for husband or 아내 (anae) for wife in formal situations. Casually, couples often use 여보 (yeobo), which is like "honey" or "dear."

Common phrases to talk about relatives in Korean

Knowing individual terms helps, but you'll want some practical phrases too. Here are the most useful ones:

These phrases come up in basically every introduction or getting-to-know-you conversation in Korean.

Using Korean family terms beyond your own family

One quirk of the Korean language that catches learners off guard: these family terms extend beyond biological family. Koreans often use family vocabulary for non-relatives as a way to show respect.

Calling an older woman 언니 when you're not related signals friendship and familiarity. Using 형 for an older male friend shows camaraderie. This usage is super common and actually helps you sound more natural in Korean.

Older strangers might get called 아저씨 (ajeossi) for men or 아줌마 (ajumma) for women, which roughly translate to "uncle" and "aunt" but really just mean middle-aged man or woman. These aren't exactly family terms, but they follow the same pattern of using familial language in broader social contexts.

The Korean term choices you make signal your relationship with someone, your relative ages, and your level of respect. It's social information packed into vocabulary.

Start with common Korean family terms

You don't need to memorize every single extended family term right away. Focus on the vocabulary that matches your life and the conversations you'll have. If you're learning Korean to connect with Korean friends, nail down the sibling terms and parent terms first. If you're learning for K-drama comprehension, those same terms plus the in-law vocabulary will cover most situations. The basic family terms used in K-dramas show up more often than you might expect.
