A featural script represents finer detail than an alphabet. Here symbols do not represent whole phonemes, but rather the elements (features) that make up the phonemes, such as voicing or its place of articulation. Theoretically, each feature could be written with a separate letter; and abjads or abugidas, or indeed syllabaries, could be featural, but the only prominent system of this sort is Korean hangul. In hangul, the featural symbols are combined into alphabetic letters, and these letters are in turn joined into syllabic blocks, so that the system combines three levels of phonological representation.

À§Å°¿¡¼ ±Ü¾î¿Â °Çµ¥ Numerous linguists have praised Hangul for its featural design, describing it as "remarkable", "the most perfect phonetic system devised", and "brilliant, so deliberately does it fit the language like a glove."[22] The principal reason Hangul has attracted this praise is its partially featural design: The shapes of the letters are related to the features of the sounds they represent: The letters for consonants pronounced in the same place in the mouth are built on the same underlying shape. In addition, vowels are made from vertical or horizontal lines so that they are easily distinguishable from consonants.
Scripts may transcribe languages at the level of morphemes (logographic scripts like hanja), of syllables (syllabic scripts like kana), or of segments (alphabetic scripts like the Roman alphabet used to write English and many other languages.). Hangul goes one step further in some cases, using distinct strokes to indicate distinctive features such as place of articulation (labial, coronal, velar, or glottal) and manner of articulation (plosive, nasal, sibilant, aspiration) for consonants, and iotation (a preceding i- sound), harmonic class, and I-mutation for vowels.
