Some linguists who study writing systems call the Semitic scripts
"abjads". In Semitic languages, words inflect around not a root but a
series of consonants; if you understand the context, you will know which
vowels apply.

Syllabaries are generally best for languages where the typical syllable is
one consonant and one vowel or just one vowel. Languages like English or
German, where syllables can be CCCVCC (streets), are a little harder to
transcribe without a godawful number of characters.
Some syllabaries fit their languages very well, such as Japanese and
Cherokee. Others don't fit so well, like the Mayan languages and
Mycenaean Greek. Writers in these scripts had various kludges to get by.
The Mycenaeans just ignored the consonants on the end of a syllable, so a
word like Agamemnon might be written A-GA-ME-NO. The Mayans covered the
end consonants by treating them as the beginning of a second syllable, one
with a silent vowel, generally the same vowel as the real syllable. A
word like 'kutz' might be written KU-TZ(u).
The best English text dealing with writing systems is _The World's Writing
Systems_, by Oxford Press, 1996, edited by Peter Daniels and (somebody)
WIlliams.
