Morphosyntactic Operation

Definition: 

A morphosyntactic operation is an ordered, dynamic relation between one linguistic form and another.

Discussion: 

A morphosyntactic operation is often manifested (or coded) by a formal operator, such as a prefix, a suffix, a stress shift or a combination of two or more of these. However, some operations are not overtly coded. One method of noting the existence of a morphosyntactic operation that has no overt realization is to posit a zero morpheme.
