+
+--1 Interlingua Lexical Paradigms
+--
+-- Aarne Ranta 2003--2005
+-- JP Bernardy 2007
+--
+-- This is an API for the user of the resource grammar 
+-- for adding lexical items. It gives functions for forming
+-- expressions of open categories: nouns, adjectives, verbs.
+-- 
+-- Closed categories (determiners, pronouns, conjunctions) are
+-- accessed through the resource syntax API, $Structural.gf$. 
+--
+-- The main difference with $MorphoIna.gf$ is that the types
+-- referred to are compiled resource grammar types. We have moreover
+-- had the design principle of always having existing forms, rather
+-- than stems, as string arguments of the paradigms.
+--
+-- The structure of functions for each word class $C$ is the following:
+-- first we give a handful of patterns that aim to cover all
+-- regular cases. Then we give a worst-case function $mkC$, which serves as an
+-- escape to construct the most irregular words of type $C$.
+-- However, this function should only seldom be needed: we have a
+-- separate module [``IrregIna`` ../../english/IrregIna.gf], 
+-- which covers irregular verbss.

+--2 Parameters 
+--
+-- To abstract over gender names, we define the following identifiers.
+
+oper
+--  Gender : Type ; 
+-- There is no grammatical gender in interlingua.
+
+---- To abstract over number names, we define the following.
+--
+--  Number : Type ; 
+--
+--  singular : Number ;
+--  plural   : Number ;
+
+-- To abstract over case names, we define the following.
+
+  nominative : Case ;
+  accusative : Case ;
+  genitive   : Case ;
+  dative     : Case ;
+  ablative   : Case ;
+
+
+-- Prepositions are used in many-argument functions for rection.
+-- The resource category $Prep$ is used.
+
+
+
+--2 Nouns
+--
+
+-- All nouns are regular, so one should use $regN$ to construct them.
+
+--3 Relational nouns 
+-- 
+-- Relational nouns ("daughter of x") need a preposition. 
+
+-- The most common preposition is "of", and the following is a
+-- shortcut for regular relational nouns with "of".
+
+  regN2 : Str -> N2 ;
+
+--2 Adjectives
+
+-- All adjectives are regular, so on should use $regA$ to construct them.
+
+--3 Two-place adjectives
+
+-- Two-place adjectives need a preposition for their second argument.
+
+  mkA2 : A -> Prep -> A2 ;
+
+
+--2 Adverbs
+
+-- Adverbs are not inflected. Most lexical ones have position
+-- after the verb. Some can be preverbal (e.g. "always").
+
+  mkAdv : Str -> Adv ;
+  mkAdV : Str -> AdV ;
+
+-- Adverbs modifying adjectives and sentences can also be formed.
+
+  mkAdA : Str -> AdA ;
+
+--2 Prepositions
+--
+-- A preposition as used for rection in the lexicon, as well as to
+-- build $PP$s in the resource API, just requires a string and an expected case.
+
+  mkPrep : Str -> Case -> Prep ;
+  noPrep : Prep ;
+
+--2 Verbs
+--
+-- Regular verbs should be constructed with $regV$. The 3 irregular verbs
+-- esser, haber and vader are available separately.
+
+
+---- Reflexive verbs.
+---- By default, verbs are not reflexive; this function makes them that.
+--
+  reflV  : V -> V ;
+  reflV v = {s = v.s ; part = v.part ; lock_V = v.lock_V ; isRefl = True} ;
+
+
+--3 2 and many-place verbs
+
+
+-- I decided to provide the following combinators for forming verbs with
+-- complex grammar rules:
+
+  prepV2 : Prep  -> V -> V2 ;
+  prepV3 : Prep -> V2 -> V3 ;
+  dirV2  : V -> V2 ;
+
+
+  mkV0  : V -> V0 ;
+  mkVS  : V -> VS ;
+--  mkV2S : V -> Prep -> V2S ;
+--  mkVV  : V -> VV ;
+  mkV2V : Prep -> Prep -> V -> V2V ;
+  mkVA  : V -> VA ;
+  mkV2A : Prep -> Prep -> V -> V2A ;
+  mkVQ  : V -> VQ ;
+  mkV2Q : Prep -> V -> V2Q ;
+  
+  mkAS  : A -> AS ;
+--  mkA2S : A -> Prep -> A2S ;
+  mkAV  : A -> AV ;
+  mkA2V : A -> Prep -> A2V ;
+--
+---- Notice: categories $V2S, V2V, V2Q$ are in v 1.0 treated
+---- just as synonyms of $V2$, and the second argument is given
+---- as an adverb. Likewise $AS, A2S, AV, A2V$ are just $A$.
+---- $V0$ is just $V$.
+--
+  V0, V2S, V2V, V2Q : Type ;
+  AS, A2S, AV, A2V : Type ;
+--
+----.
+----2 Definitions of paradigms
+----
+---- The definitions should not bother the user of the API. So they are
+---- hidden from the document.
