View source for Mapping Principle (in morphology)

==Definition==
In morphology, the '''Mapping Principle''' is a principle proposed by Sproat (1985) to relate the phono-morphological and the syntactico-semantic level of representation of complex words to each other. He basically proposes the Mapping Principle to account for the so-called [[bracketing paradox]]es.  

==Example==
A standard example of a bracketing paradox is ''ungrammaticality''. The phono-morphological representation of this form will include the information that ''un-'' is an unstressed prefix, and that ''-ity'' is a suffix which attracts stress to the previous syllable. The syntactico-semantic representation will include the information that ''un-'' selects adjectives and means 'NOT', and that ''-ity'' creates abstract nouns from adjectives. Furthermore, at the phono-morphological level hierarchical structure plays a relatively small role. Instead, strict adjacency tends to be much more relevant. On the other hand, at the syntactico-semantic level, linear order seems to be of little importance. Here, hierarchical structure or sisterhood between morphemes is crucial. At the syntactico-semantic level the representations of ungrammaticality in (i) are equivalent, since linear order is irrelevant. At the phono-morphological level the representations of ungrammaticality in (ii) are also equivalent, since hierarchical structure is irrelevant at this level of representation:

 (i)  [[UN [GRAMMATICAL]A ]A ITY]N <=> [ITY [UN [GRAMMATICAL]A ]A ]N 

 <=> [[GRAMMATICAL]A UN]A ITY]N <=> [ITY [[GRAMMATICAL]A UN]A ]N
 
 (ii) [[un [grammatical]] ity] <=> [un [[grammatical] ity]]

Sproat defines his Mapping Principle in such a way that [[un [grammatical]] ity] can be rebracketed as [un [[grammatical] ity]], since morphological principles such as level ordering demand it.
