PHONOLOGY/MORPHOLOGY: a rule which changes already specified information,
and renders the output form distinct from the input.
EXAMPLE: the feature [voice] is distinctive within the class of obstruents,
but non-distinctive in the class of sonorants. If there is a rule which devoices
obstruents in a particular environment, say word final, this rule will be
structure-changing if it changes [-son, +voice] into [-son, -voice].
