Hangul syllable Bim

The word around it determines the sense. In 빔 프로젝터, the phrase means projector; 레이저 빔 means laser beam. The stage-light term 빔 라이트 uses it for a narrow beam. A Korean government terminology entry also uses 빔 for a ship’s maximum width.

Where did Hangul come from?

Hangul was designed to make Korean easier to write. Idu, Gugyeol, and Hyangchal were older methods that used Chinese characters to write Korean. Hangul later appeared in Buddhist and Confucian texts, everyday writing, laws, and government documents. It became official in 1894 and faced suppression after 1910.
