Hangul
Six pillars: 아 어 오 우 으 이
If you only keep six vowels, keep these. They carry half of Seoul.
ㅏ a as in father. ㅓ eo — a darker 'uh', like the vowel in 'sun' but rounder. Mixing 아/어 is the fastest way to sound lost.
ㅗ o (oh). ㅜ u (oo). ㅡ eu — unrounded, like a muffled 'uh' with a flat mouth. ㅣ i (ee).
Say 아이, 어우, 오이 out loud. Your mouth should move. If it doesn't, you are still reading English.
