PHONOLOGY/MORPHOLOGY: rule which fills in predictable or redundant
information. Redundancy rules have two important properties: (a) they do not
create structure, and (b) they do not alter structure.
EXAMPLE: the fact that sonorants in English are always voiced, as
opposed to obstruents, can be captured by leaving the feature [voice] unspecified,
and fill in [+voice] by a redundancy rule. The idea behind redundancy rules and
underspecification is that redundant
information can be left unspecified in the grammar (usually the lexicon), and that
a grammar which contains less (idiosyncratic) information is more highly valued
than a grammar which contains more (every thing else being the same).
