How to say ㅇ
이응With ㅇ (ieung), at the start of a syllable ㅇ has no sound at all; the vowel begins directly. At the end of a syllable it is ng, as in English 'sing', with the back of the tongue raised.
Every Korean syllable begins with a consonant letter, so ㅇ fills that spot when the sound starts with a vowel: 아 (a), 우유 (uyu, milk). As a 받침 it is romanized ng, as in 방 (bang, room).
How ㅇ ends a syllable
In 공 (ball) the back of the tongue lifts while the sound hums through the nose, the same ng as in “song”. Unlike most finals, ㅇ does not jump forward before a vowel: 공이 stays [공이].
Unlike most finals, ㅇ (ieung) sounds like itself at the bottom of the block, only shorter and unreleased.

ㅇ and its look-alikes

|---|---|---|
| ㅇ | 이응 (ieung) | nothing at the start, ng as in ring at the end |
| ㅎ | 히읗 (hieut) | h, as in hat |
Why ㅇ looks the way it does
ㅇ copies the shape of the throat, and it has no sound as a first consonant. ㅎ was made from it by adding strokes.
ㅇ (ieung) belongs to the group made with the throat, because the original design of Hangul sorted consonants by the part of the mouth that makes them.
