In this paper we show that an account for coordination can be constructed us- ing the derivation structures in a lexical- ized Tree Adjoining Grammar (LTAG). We present a notion of derivation in LTAGs that preserves the notion of fixed constituency in the LTAG lexicon while providing the flexibility needed for coordination phenomena. We also discuss the construction of a practi- cal parser for LTAGs that can han- dle coordination including cases of non- constituent coordination.
