In applications such as translation and paraphrase, operations are carried out on grammars at the meta level. This pa- per shows how a meta-grammar, defining structure at the meta level, is useful in the case of such operations; in particu- lar, how it solves problems in the current definition of Synchronous TAG (Shieber, 1994) caused by ignoring such structure in mapping between grammars, for appli- cations such as translation. Moreover, es- sential properties of the formalism remain unchanged.
