What language is the Hangul script based on?

Each Hangul character, called a "syllabic block," is formed by combining an initial consonant (chosong) with a medial vowel (jungseong), and in many cases, a final consonant (jongseong). These components are assembled to create a complete character resembling a square, which stands for a single syllable. For example, the Korean word 한글 (Hangul) consists of two syllabic blocks: 한 (han) and 글 (geul). This unique feature allows for a modular approach when it comes to spelling words, giving the writer more flexibility and precision.
