--2 Parameters 
--
-- To abstract over gender names, we define the following identifiers.

oper
  NGender : Type ; 

  masculine : NGender ;
  feminine  : NGender ;
  neuter    : NGender ;
  
  Gender : Type ;
  
  Masculine : Gender ;
  Feminine  : Gender ;
  
--To abstract over animacy, we define the following :  

  Anim : Type ;
  
  animate   : Anim ;
  inanimate : Anim;
  
-- To abstract over number names, we define the following.

  Number : Type ; 

  singular : Number ;
  plural   : Number ;

-- prepositions which require cases :
   
   Preposition : Type ;
 
 NCase : Type ;
  Acc : NCase ;
  Dat : NCase ;
  Gen : NCase ;
    
  mkPrep : Str -> NCase -> Prep ;
  noPrep : NCase -> Prep ;

--2 Nouns



--3 Relational nouns 
-- 
-- Relational nouns need a noun and a preposition. 

 mkN2 : N -> Prep -> N2 ;
 mkN2 n p = n ** {lock_N2 = <> ; c2 = p};

-- Three-place relational nouns need two prepositions.

mkN3 : N -> Prep -> Prep -> N3 ;
mkN3 n p q = n ** {lock_N3 = <> ; c2 = p ; c3 = q };



--3 Proper names and noun phrases
--
-- Proper names need a string and a gender. If no gender is given, the
-- feminine is used for strings ending with "e", the masculine for other strings.

--3 Two-place adjectives
--
-- Two-place adjectives need a preposition for their second argument.
