          | On 
            the basis of the ability of showing a three-way opposition in person, 
            viz., I, II and III persons, the pronouns could be differentiated 
            from the nouns and the demonstratives as in : | 
         
          | 
 
               
                | 
                     
                      | ni | `I’ |   
                      | no | `you’ |   
                      | pa | `he’ |   
                      | li | `she’ |  |  
 | 
         
          | The 
            pronouns also show a three-way opposition in number viz., singular, 
            dual and plural, as in | 
         
          | 
 
               
                | 
                     
                      | (i) | ni | `I’ |   
                      |  | nikuzo | `We 
                        (two)’ |   
                      |  | ni  ł | `We 
                        (plural)’ |   
                      | (ii) | no | `you 
                        (sg)’ |   
                      |  | nokuzo | `you 
                        (dual)’ |   
                      |  | no  ł | `you(pl)’ 
                        etc. |   
                      | (iii) | pa | `he’ |   
                      |  | pama | `they 
                        (dual)' |   
                      |  | panį  ł | `they 
                        (plural)' |  |  
 | 
         
          | whereas 
            the demonstratives show only a two-way opposition in number viz., 
            singular vs plural as in: | 
         
          | 
 
 | 
         
          | The 
            nouns are capable of showing a three-way opposition in number, but 
            usually do not mark this difference: e.g. | 
         
          | 
 
               
                | 
                     
                      | timi 
                        lakhi | `one 
                        man’ |   
                      | time 
                        k  ma | `two 
                        men’ |   
                      | timģqó | `men’ |  |  
 | 
         
          | Even 
            here nouns referring to non-human beings do not take the form köma 
            which indicates duality. | 
         
          | A 
            pronoun may be defined as that grammatical class which at the paradigmatic 
            level shows a three-way opposition in number and person and capable 
            of taking case markers and at the systematic level is capable of preceding 
            a postposition and/or particle but incapable of being modified by 
            an adjective and at the sentence level substitutes a noun: | 
         
          | Demonstratives | 
         
          | Both 
            the nouns and the demonstratives share at the paradigmatic level the 
            feature of taking the case suffixes and at the systematic level, the 
            privilege of preceding postpositions and the plural marker. e.g. | 
         
          | 
 
               
                | 
                     
                      | hipaqóye 
                        ac  kini | `these 
                        are two dogs’ |   
                      | anuye 
                        akipici | `the 
                        child (is) lazy’ |   
                      | tiye 
                        lono ic  lņ | `give 
                        me from that’ |   
                      | anulono | `from 
                        the child’ |   
                      | ti | `that’ |   
                      | tipaqó | `those’ |   
                      | kaku | `book’ |   
                      | kakuqó | `books’ |  |  
 | 
         
          | However, 
            when a NP has both a demonstrative and a noun, the demonstrative takes 
            the case suffix/focus marker and the plural marker as in : | 
         
          | 
 
               
                | 
                     
                      | ilimģ 
                        tipawye qhemFay | `that 
                        girl (is) tall’ |   
                      | ilimģ 
                        tipaqóye qhemFay | `those 
                        girls (are) tall’ |  |  
 | 
         
          | In 
            a NP1 NP2 type of sentence, both a demonstrative and noun can occur 
            alone in NP2 position, but only a noun or adjective can occur alone 
            in NP2 position and not a demonstrative as in : | 
         
          | 
 
               
                | 
                     
                      | hie 
                        ac  lakhģ | `this 
                        (is) a dog’ |   
                      | anuye 
                        akipici | `the 
                        child (is) lazy’ |   
                      | hie 
                        inu | `this 
                        (is) my child’ |  |  
 | 
         
          | A 
            demonstrative may be formally defined as that grammatical class which 
            at the paradigmatic level is capable of taking case suffixes and at 
            the systematic level is capable of preceding a post position/plural 
            marker and when both a demonstrative and a noun occurs in a NP, the 
            demonstrative takes both the case and plural markers, if any, but 
            can not occur alone in a NP3 position of NP1, NP2 type of sentence. | 
         
          | Nouns | 
         
          | The 
            nouns in Sema are capable of taking gender, number and case markers 
            including the postpositions and could also function as the nucleus 
            of a noun phrase as in : | 
         
          | 
 
               
                | 
                     
                      | anuye | `the 
                        child’ |   
                      | amsili | `she 
                        buffalo’ |  |
