| and ja:dyba: are derived by adding -skia, -chonma
                and -ba to the nominal stems.

                | Notes
 | 
                    
                | 1.
                  The forms which end in -o have alternant forms
                  like bomon and bax8mon. 
 | 
                    
                | 2. Purki resembles
                  Hindi in this respect. The ergative suffix-is can be compared
                  with -na in Hindi. 
 | 
                    
                | 3. This statement does
                  not hold good in all cases. There are sentences in which the
                  object under question takes -a. Examine the following
                  sentences in Purki.

                |  | 
                    
                | There are only two
                  verbs rdu  s
                  ‘beat’ and rgat ‘love’ in the whole of
                  data which are found to be exceptions to our generalization.
                  -a is an allomorph of the morpheme -la, which is homophonous
                  expressing both dative and locative cases. One possible
                  solution would be to treat khoa and khera  a
                  as dative or locative. I am not clear what case should be
                  assigned to these nouns. 
 
 | 
                    
                | 4. There are two ways
                  of analysing the verbal roots which end in -s. One way is to
                  treat that the past tense is -s. occurs whenever the
                  verbal roots ends i -s (there are other environments also).
                  The alternative would be that these varbal roots also take -s
                  as the past tense maker. This treatment requires a
                  morphophonemic rule which would be as follows : 
 | 
                    
                | s -> Ę /s-
 
 
 | 
                    
                | 5. The past tense and
                  future tense suffixes are added to the verbal roots. But the
                  present tense suffix is added to the verbal stems. The tense
                  suffixes are not added either to the verbal roots or verbal
                  stems uniformly.

                | 6. This statement is
                  valid only when the tense is either past or present. Only duk
                  occurs as the durative aspect when the tense is future. yot
                  is not found occurring if the tense is future. In my data, we
                  do not have sentence like,
