Relative Clause Trees

For relative clause trees, the following naming conventions have been adopted: if the wh-moved NP is overt, it is not explicitly represented. Instead the index of the site of movement (0 for subject, 1 for object, 2 for indirect object) is appended to the N. So $\beta$N0nx0Vnx1 is a subject extraction relative clause with NP_w substitution and $\beta$N1nx0Vnx1 is an object extraction relative clause. If the wh-moved NP is covert and Comp substitutes in, the Comp node is represented by c in the tree name and the index of the extraction site follows c. Thus $\beta$Nc0nx0Vnx1 is a subject extraction relative clause with Comp substitution. Adjunct trees are similar, except that since the extracted material is not co-indexed to a trace, no index is specified (cf. $\beta$Npxnx0Vnx1, which is an adjunct relative clause with PP pied-piping, and $\beta$Ncnx0Vnx1, which is an adjunct relative clause with Comp substitution). Cases of pied-piping, in which the pied-piped material is part of the anchor have the anchor capitalized or spelled-out (cf. $\beta$Nbynx0nx1Vbynx0 which is a relative clause with by-phrase pied-piping and NP_w substitution.).
