PHONOLOGY/MORPHOLOGY: a property of (lexical) rules which entails that
they cannot introduce segments which are not otherwise motivated as underlying
phonological segments of the language.
EXAMPLE: the underlying sound inventory of Dutch does not contain voiceless
sonorants, but it does contain voiced and voiceless obstruents. Furthermore, Dutch
has a rule of final devoicing, but characteristically this rule does not effect
sonorants. Hence, the rule of final devoicing is structure preserving.

SYNTAX: a rule or rule system is structure preserving if its output is independently available as an underlying (underived) structure. The hypothesis that natural language grammars are structure preserving has first been elaborated in Emonds (1970), and is taken for granted in much ongoing work.
