In addition, regional variations do exist within the Korean language, but for the purpose of this guide, we will focus on the standard language. Let’s get started!

When learning a foreign language, knowing how to express your age is always a great starting point. So, if you want to say “I am ten years old” in Korean, you’ve come to the right place. We will explore both formal and informal ways, providing tips and examples along the way.

Formal Expressions

In formal situations, such as addressing older individuals, strangers, or people in positions of authority, you should use the formal language in Korean. Here are some ways to say “I am ten years old” formally:

1. 제 나이는 십살입니다 (Je nai-neun sip-sal-im-ni-da)

This is the standard, straightforward way to express your age formally. In this sentence, “제 나이는” (je nai-neun) means “my age,” and “십살입니다” (sip-sal-im-ni-da) means “is ten years old.” Here’s an example:

Example: 제 나이는 십살입니다. (Je nai-neun sip-sal-im-ni-da) – I am ten years old.

2. 저는 십살입니다 (Jeo-neun sip-sal-im-ni-da)

This expression is more formal and polite since it omits the possessive pronoun “제 (je)” that represents “my.” Here’s an example:

Example: 저는 십살입니다. (Jeo-neun sip-sal-im-ni-da) – I am ten years old.

These two formal expressions should be used when talking to adults, elders, or in formal settings such as official meetings or interviews.

Informal Expressions

In informal situations, such as talking to friends, family members, and peers, a different language level is used. Here are some informal ways to say “I am ten years old” in Korean:

1. 나는 열 살이야 (Na-neun yeol sal-i-ya)

In this expression, “나는” (na-neun) means “I am,” “열 살” (yeol sal) means “ten years old,” and “이야” (i-ya) is the informal way of saying “am.” Here’s an example:

Example: 나는 열 살이야. (Na-neun yeol sal-i-ya) – I am ten years old.

2. 내 나이는 열 살이야 (Nae nai-neun yeol sal-i-ya)

This expression is similar to the previous one but includes the possessive pronoun “내 (nae),” meaning “my.” Here’s an example:

Example: 내 나이는 열 살이야. (Nae nai-neun yeol sal-i-ya) – I am ten years old.

These informal expressions are suitable for communicating with friends, siblings, and people of similar age groups.

Tips and Cultural Context

While learning the phrases is essential, understanding the cultural context can help improve your overall Korean communication skills. Here are some tips:

1. Use the correct ending

Korean language has various speech levels, indicated by different sentence endings. Using the wrong ending could result in unintended rudeness or formality. Make sure to use the correct ending according to the formal or informal context.

2. Add a polite ending in formal situations

In extremely formal settings, it is common to add the polite ending “-요” (yo) to any of the formal expressions mentioned earlier. This helps to further show respect and politeness.

3. Learn different counters

Korean numbers have specific counters for different objects or situations. For expressing age, the counter “살” (sal) is used. Learning these counters enhances your ability to communicate accurately in Korean.

4. Pay attention to the speaker’s age

In Korean culture, it is common to adjust your language and speech level based on the age difference between speakers. Respect for elders is highly valued, so if you are speaking with someone significantly older, it’s best to use the formal expressions.

Remember, language is a living organism that reflects the culture and customs of its speakers. By understanding and incorporating cultural nuances, your Korean communication will be more effective and respectful.
