A syllabary is a phonetic writing system like an alphabet. Unlike an alphabet the sound-unit which is written is a syllable rather than a phoneme. In Japanese KataKana the sound ka is represented by one glyph. Syllabaries tend to be bigger than alphabets (Japanese KataKana requires about 60 different characters, while the Korean Hangul requires tens of thousands).See Also: abjad, abugida, alphabet and the relevant Wikipedia article.
