Quick Tip #1: Hangul Was Designed, Not Random

One of the coolest things about Hangul is that it wasn’t just invented randomly. It was designed in the 15th century with inspiration from nature and human beings.

All vowels come from three basic shapes:

• Dot (•) = the sky

• Horizontal line (ㅡ) = the earth

• Vertical line (ㅣ) = a person

From these, the vowels split into two main groups:

• Vertical vowels: ㅏ, ㅑ, ㅓ, ㅕ, ㅣ

• Horizontal vowels: ㅗ, ㅛ, ㅜ, ㅠ, ㅡ

Quick Tip #2: The Y-Sound Rule

Here’s an easy rule:

If a vowel has two lines instead of one, it adds a Y sound.

• ㅏ = a → ㅑ = ya

• ㅗ = o → ㅛ = yo

Simple, right? Let’s go through them all.

Vertical Vowels: The “AH” Group

These vowels are built with a vertical line (ㅣ) as the base.

• ㅏ (a) → “ah,” like in father.
  Example: 아빠 (appa = dad)

• ㅑ (ya) → “yah,” like in yard.
  Example: 야구 (yagu = baseball)

• ㅓ (eo) → soft “uh,” like in son.
  Example: 어머니 (eomeoni = mother)

• ㅕ (yeo) → “yuh,” like in young.
  Example: 여름 (yeoreum = summer)

• ㅣ (i) → “ee,” like in see.
  Example: 이름 (ireum = name)

---

Horizontal Vowels: The “OH” Group

These vowels are built with a horizontal line (ㅡ) as the base.

• ㅗ (o) → “oh,” like in open.
  Example: 오늘 (oneul = today)

• ㅛ (yo) → “yo,” like in yoga.
  Example: 요리 (yori = cooking)

• ㅜ (u) → “oo,” like in blue.
  Example: 우리 (uri = we/us)

• ㅠ (yu) → “you,” like the pronoun.
  Example: 유명 (yumyeong = famous)

• ㅡ (eu) → “eu,” a unique sound with no English equivalent. Keep your lips wide and flat.
  Example: 음식 (eumsik = food)

Practice Drill: Minimal Pair Challenge

These pairs often get mixed up. Try saying them side by side:

• ㅏ (a) vs. ㅓ (eo) → 아 vs 어

• ㅗ (o) vs. ㅜ (u) → 오 vs 우

• ㅏ (a) vs. ㅑ (ya) → 아 vs 야

• ㅗ (o) vs. ㅛ (yo) → 오 vs 요

• ㅡ (eu) vs. ㅣ (i) → 으 vs 이

Practice these daily, and soon the sounds will come naturally.

Review & Mnemonics

Here’s a quick recap of the 10 vowels:

ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, ㅣ

Memory tips:

• Right or top line → bright sounds (ㅏ = ah, ㅗ = oh)

• Left or bottom line → darker sounds (ㅓ = uh, ㅜ = oo)

• Double lines = add Y (ㅑ, ㅕ, ㅛ, ㅠ)

• ㅡ = lips spread flat
