DTG are designed to share some of the advantages of TAG while overcoming some of its limitations. DTG involve two com- position operations called subsertion and sister-adjunction. The most distinctive fea- ture of DTG is that, unlike TAG, there is complete uniformity in the way that the two DTG operations relate lexical items: subsertion always corresponds to comple- mentation and sister-adjunction to modi- fication. Furthermore, DTG, unlike TAG, can provide a uniform analysis for wh- movement in English and Kashmiri, des- pite the fact that the wh element in Kash- miri appears in sentence-second position, and not sentence-initial position as in Eng- lish.
