나이 → 연세: When "age (noun)" Needs Respect

In Korean, age (noun) has completely different words depending on who you're talking to or about.

The Rule

In Korean, "age (noun)" isn't just one word — it changes based on your relationship with the listener and the person you're talking about. This isn't just about being polite; using the wrong level can be genuinely offensive. The four key levels for "age (noun)": • 반말 (casual): 나이 • 해요체 (polite): 나이 • 합쇼체 (formal): 나이 • 존칭 (honorific): 연세

Why English Speakers Get It Wrong

English has one word for "age (noun)" regardless of who you're talking to. You might add "please" or change your tone, but the verb itself stays the same. In Korean, the entire word changes. This isn't like French "tu/vous" — Korean has MORE levels and the honorific forms can be completely different words, not just different endings. 나이 and 연세 don't even look related, but they mean the same thing at different politeness levels.

How It Works

Asking an elderly person's age 연세 is the honorific word for age. Use with elders. 나이 is neutral/casual. The hierarchy: 1. 반말 (나이) — Friends your age, younger people 2. 해요체 (나이) — Default safe level, strangers, colleagues 3. 합쇼체 (나이) — Business settings, news, presentations 4. 존칭 (연세) — About/to elders, customers, respected figures

Real Examples

• 나이 (nai) — "age (noun)" (to friends, casual) • 나이 (nai) — "age (noun)" (polite daily conversation) • 나이 (nai) — "age (noun)" (formal settings) • 연세 (yeonse) — "age (noun)" (about respected people) Correct usage: 연세가 어떻게 되세요? (yeonsega eotteohge doeseyo?)

Common Mistakes

❌ 나이가 몇이에요? (naiga myeotieyo?) ✅ 연세가 어떻게 되세요? (yeonsega eotteohge doeseyo?) → 연세 is the honorific word for age. Use with elders. 나이 is neutral/casual. ❌ Using 나이 to someone older or a stranger ✅ Default to 나이 when unsure → When in doubt, go one level higher. Koreans appreciate over-politeness from foreigners more than under-politeness.

Quick Tip

When you're unsure which level to use, default to 해요체 (나이). It's polite enough for almost every situation and won't offend anyone. Only use 반말 (나이) when someone explicitly tells you it's okay. For the honorific form 연세, practice using it when talking ABOUT (not just to) respected people. Even when grandma isn't in the room, you should use the honorific form when mentioning her.

Safe default: 나이. When talking about elders: 연세.
