The Lexicalist-interpretive approach to inalienable possession adopted in this paper proposes that body parts are generated with either the article (the unmarked determiner) or the possessive adjective (the marked determiner). The unmarked body part is codesignate with the indirect object; in the case of pseudo-transitives--a clearly delimited group which constitutes an exception to the rule--codesignation occurs between the body part and the sentence subject. Possessive adjectives are coreference marked by the same mechanism whether they modify body parts or other possessions. This is justified, as there is no syntactic distinction between alienable and inalienable objects once modified by possessive adjectives. (Author)
