Readability
The organization of Hangul syllables—with individual phonemes clustered into a syllable, rather than organized in a horizontal line as in English—is thought by some observers to be a powerful reading aid. Because of the clustering of syllables, words are shorter on the page than their linear counterparts would be, and the boundaries between syllables are easily visible (which may aid reading, if segmenting words into syllables is more natural for the reader than dividing them up into phonemes). Because the component parts of the syllable are relatively simple phonemic characters, the number of strokes per character on average is lower than in Chinese characters. Unlike syllabaries, such as Japanese kana, or Chinese logographs, none of which encode the constituent phonemes within a syllable, the graphic complexity of Korean syllabic blocks varies in direct proportion with the phonemic complexity of the syllable. Unlike linear alphabets such as Latin-derived ones, the Korean orthography allows the reader to "utilize both the horizontal and vertical visual fields"; finally, since Hangul syllables are represented both as collections of phonemes and as unique-looking graphs, they may allow for both visual and aural retrieval of words from the lexicon.
