Feature Geometry and Feature Spreading

Abstract

A feature organization ("feature tree") is presented that takes direct account of the anatomical interpretation of features. It is shown that the assimilation of subsets of features cannot be formally expressed by linking higher nodes in the feature tree. This restriction, however, does not render the notation incapable of expressing Clements's insight that only certain feature sets may be assimilated simultaneously. Examples of incomplete assimilation are examined that have been cited in the literature as requiring a feature organization that disregards the anatomical interpretation of features. It is shown that all relevant generalizations can be captured by the anatomically motivated feature tree.
