By means of a factorization of linear precedence (LP) information in Tree Adjoining Grammar (TAG), the possibility to capture syntactic generalizations can be enhanced, especially with respect to languages which exhibit relative free word order. In TAG(LD/LP) LP-information is factorized in a way reminiscent of the ID/LP format of CFGs. However, in contrast to its context-free counterpart, in TAG(LD/LP) entanglement of constituents is allowed by admitting not only the permutation of sister nodes, but also of non-sister nodes in a structural description. In this paper a generalization of the predictive left-to-right parser for TAG is presented which is able to handle a restricted variant of TAG(LD/LP), which allows the permutation of sister nodes and non-sister nodes within elementary structures, the basic building blocks of TAG(LD/LP).
