Vowels that begin with sky, person, and earth

Hangul's basic vowels begin with three shapes meaning sky, person, and earth. This same principle is used in the Cheonjiin input for My Hangul Word.

  1. A dot for heaven

    A round dot represents heaven.

  2. A line for a person

    A vertical line represents a person.

  3. A line for earth

    A horizontal line represents earth.
