MORPHOLEX lists all the regular inflectional + derivational affixes in the families of a text or word list according to
Bauer & Nation's (1993) framework of morphological complexity.
'Regular' here means attached to an identifiable base word, or free morpheme, like quick + ly, but not gorm + less, because gorm* is not a word. This routine is a 'profiler' in that like VP it gives a percent of tokens at each level and the specific affixes needed to achieve 95% and 98% coverage in the list/text. The present accuracy for this routine is average
95% 98% 99.1%.
