For this exercise, base yourselves on gramar9.lfg. This grammar continues on with re-engineering the toy English grammar into South Asian syntax and vocabulary. This particular grammar is assuming Urdu.
The control and complementation (XCOMP, COMP) of grammar8.lfg has not been integrated.
Expand your grammar to deal with some Tense/Aspect. Your grammar should either parse the following Urdu examples or the equivalent in a South Asian language of your choice.
alI nE sara kO dEkH-A tH-A Ali Erg Sara Acc see-Perf.M.Sg be.Past-M.Sg 'Ali had seen Sara' (Past Perfect)
alI sara kO dEkH-tA hE Ali.Nom Sara Acc see-Impf.M.Sg be.Pres.3.Sg 'Ali looks at Sara' (Present/Habitual)
alI sara kO dEkH rah-A hE Ali.Nom Sara Acc see Prog-M.Sg be.Pres.3.Sg 'Ali is looking at Sara' (Present Progressive)
alI sara kO dEkH rah-A tH-A Ali.Nom Sara Acc see Prog-M.Sg be.Past-M.Sg 'Ali is looking at Sara' (Past Progressive)
You will need to complicate the rule introducing the verbal complex (VC) in order to implement the above.
Expand your grammar to deal with some Modality. Your grammar should either parse the following Urdu example or the equivalent in a South Asian language of your choice.
alI kO kitAb paRH-nI cahiye Ali Dat book.Nom.F.Sg read-Inf.F.Sg need.Sg 'Ali needs to read a/the book.'
You will have to complicate your VC rule further to integrate modality. The target f-structure should involve an XCOMP and look something like below. Note that you are dealing with a dative subject here as well and that you will have to adjust the GF template accordingly.
[PRED 'need<(^SUBJ),(^XCOMP)>' SUBJ [PRED 'Ali', CASE dat, NUM sg, PERS 3, GEND masc] XCOMP [PRED 'read<(^SUBJ),(^OBJ)>' SUBJ [ALI] OBJ [PRED 'book', CASE nom, NUM sg, PERS 3, GEND fem] VFORM inf] MOOD INDICATIVE TENSE PRES MODALITY obligation ]
