Suffix classes

This list compares the classification of verb suffixes in Oswalt's 1961 dissertation with the lexical levels in Buckley's 1994 analysis using more modern phonological theory. It is intended as a guide for readers with more technical interests.

Buckley 1994 originally proposed five "lexical levels" based on phonological patterns such as Iambic lengthening. In a simpler conception, levels 1–3 can be considered Stem-level, and levels 4–5 are Word-level. 

Oswalt 1961 has a complicated classification of all affixes, depending on where they occur in the overall word. The first letter identifies what kind of STEM the affix attaches to; usually this is v for verb. The number gives the position in the word, from 1 to 15. Class 14 is a special category: every verb must contain exactly one suffix from this group. 

The last letters identify what kind of word results from the morphological operation.
