Models of morphology

There are three principal approaches to morphology, which each try to capture the distinctions above in different ways. These are,

* Morpheme-based morphology, which makes use of an Item-and-Arrangement approach.
* Lexeme-based morphology, which normally makes use of an Item-and-Process approach.
* Word-based morphology, which normally makes use of a Word-and-Paradigm approach.

Note that while the associations indicated between the concepts in each item in that list is very strong, it is not absolute.
