Writing Systems of the World 1, Exercise 1: classifying scripts

Greek               alphabet
Hebrew              abjad
Japanese kana       syllabary
Devanagari          abugida
Chinese characters  logographic
Hangul              featural

The disputed one is the featural class. The Writing system article says the
class was proposed by Geoffrey Sampson, with Hangul as the main example, and
that many scholars, including John DeFrancis, dispute the classification.

Remember the article's caveat that most systems are mixed, so these labels
name the main tendency of each script. (Japanese, for example, also uses
Chinese characters; Chapter 4 returns to this.)
