Seven constraints on consonant sequences in Israeli Hebrew, which are
the modern reflexes of older Semitic constraints, are discussed in
relation to three levels: (i ) as Morpheme Structure Conditions imposed
on the under lying consonantal root morpheme; (ii) as Surface Phonetic
Constraints im posed on the word regardless of morphemic content; (iii)
as Morpheme Sensi tive Surface Constraints, which as the name suggests,
are placed on words, but are sensitive to morphemic structure and
categorization. The third set of constraints has not been seriously
considered in the recent litera ture, yet at least some of the seven
different constraints must be regarded as morpheme-sensitive. The root
level is seen to play little or no role in determining these
constraints.
