    <Paragraph position="0"> We have sketched an application of the Paninian Grammar Framework to Arabic, and outlined an approach to deriving a common logical form for equivalent sentences in Hindi and Arabic. In particular, the PGF analysis given here highlights the similarity of resumptive pronoun affix in Arabic to the co-relative in Hindi.</Paragraph>
    <Paragraph position="1"> This is a first step toward developing comprehensive Paninian dependency grammars of Arabic and Hindi, with a view to applying the grammars to machine translation. Further development of the grammar is necessary before it is clear that PGF is capable of handling all the requirements of a MT system. In particular, the suitability of PGF for generation needs to be explored, particularly with respect to generating appropriate word orders in the target language.</Paragraph>
    <Paragraph position="2"> In terms of on-going development of PGF as a theory for computational linguistics, (Bharati et al., 1996b) and (Pedersen, 2001) have compared PGF to Lexical Functional Grammar (Bresnan and Kaplan, 1982) and Lexicalised Tree Adjoining Grammar (Joshi, 1987) with encouraging results. However a systematic comparison of PGF to more recent dependency grammar formalisms, such as DACHS and TDG, has not yet been done. Given the strong parallels with recent work in these formalisms (cf. (Kruijff and Duchier, 2003)), such an investigation is now essential.</Paragraph>
