| Term | Definition |
| Item and Arrangement | word-forms are constructed by taking morphemes (the items) and stringing them together in the right order (the arrangement) |
| Item and Arrangement Example | morpheme "play + (past) -ed = word-form (played) |
| Item and Arrangement Association | with the American Structuralists following Bloomfield in the 1930s, 40s, 50s |
| IA Correspondence | clear mapping of morphemes and syntax |
| Item and Process | making word-forms involves taking a base (the item) and applying a series of processes to it, each with formal change and corresponing piece of meaning |
| Item and Process Association | with earlier Structuralists like Sapir (1920s) and earlier linguists working on a language history and diachrony |
| Item and Process Examples | affixation, reduplication, vowel mutation, stress shift |
| IP Typology | processed-based and incremental |
| IP Advantage | more complex than IA, but deals more easily with things like sang |
| Word and Paradigm | full meaning and function of a word already determined before we start putting together its form |
| Word and Paradigm Assuption | realizational rules derive surface form for abstract content GUT(+neuter, +acc., +str) |
| WP typology | process based and realizational: word and meaning determined independently, then word-form realizes the meaning by applying the processes |
| WP approach | designed to handle deviations from the agglutinative ideal |
| What makes theoretical linguists nervous about WP | extremely powerful in its unadulterated form |
| Problem 2 with WP | if any imaginable system of morphology can be described, this theory can't tell us what phenomena are possible in human language |
| Distributed Morphology | abstract word structure put together in the syntax, out of syntactic units which have meaning but no form, appropriate vocabulary insertion rules then introduce form which realize those syntacic heads, provide sound to go with meaning |
| DM Approach | piece based and realizational, words are put together from pieces |
