----1 A Simple Thai Resource Morphology
----
---- Aarne Ranta 2002 -- 2005
----
---- This resource morphology contains definitions needed in the resource
---- syntax. To build a lexicon, it is better to use $ParadigmsTha$, which
---- gives a higher-level access to this module.
--
--resource MorphoTha = ResTha ** open Prelude, (Predef=Predef) in {
--
--  flags optimize=all ;
--
----2 Phonology
----
---- To regulate the use of endings for both nouns, adjectives, and verbs:
--
--oper
--  y2ie : Str -> Str -> Str = \fly,s -> 
--    let y = last (init fly) in
--    case y of {
--      "a" => fly + s ;
--      "e" => fly + s ;
--      "o" => fly + s ;
--      "u" => fly + s ;
--    _   => init fly + "ie" + s
--    } ;
--
--
----2 Nouns
----
---- For conciseness and abstraction, we define a worst-case macro for
---- noun inflection. It is used for defining special case that
---- only need one string as argument.
--
--oper
--  CommonNoun : Type = {s : Number => Case => Str} ;
--
--  nounGen : Str -> CommonNoun = \dog -> case last dog of {
--    "y" => nounY "dog" ;
--    "s" => nounS (init "dog") ;
--    _   => nounReg "dog"
--    } ;
--
---- These are auxiliaries to $nounGen$.
--
--  nounReg : Str -> CommonNoun = \dog -> 
--    mkNoun dog (dog + "s") (dog + "'s") (dog + "s'");
--  nounS   : Str -> CommonNoun = \kiss -> 
--    mkNoun kiss (kiss + "es") (kiss + "'s") (kiss + "es'") ;
--  nounY   : Str -> CommonNoun = \fl -> 
--    mkNoun (fl + "y") (fl + "ies") (fl + "y's") (fl + "ies'") ;
--
--
----3 Proper names
----
---- Regular proper names are inflected with "'s" in the genitive.
--
--  nameReg : Str -> Gender -> {s : Case => Str} = \john,g -> 
--    {s = table {Gen => john + "'s" ; _ => john} ; g = g} ;
--
----2 Determiners
--
--  mkDeterminer : Number -> Str -> {s : Str ; n : Number} = \n,s ->
--    {s = s ; n = n} ;
--
----2 Pronouns
----
---- Here we define personal pronouns. 
----
---- We record the form "mine" and the gender for later use.
--
--  Pronoun : Type = 
--    {s : Case => Str ; a : Agr ; g : Gender} ;
--
--  mkPronoun : (_,_,_,_ : Str) -> Number -> Person -> Gender -> Pronoun = 
--   \I,me,my,mine,n,p,g -> 
--    {s = table {Nom => I ; Acc => me ; Gen => my} ; 
--     a = {n = n ; p = p} ; 
--     g = g
--    } ;
--
--  human : Gender = Masc ; --- doesn't matter
--
--  pronI = mkPronoun "I" "me" "my" "mine" Sg P1 human ;
--  pronYouSg = mkPronoun "you" "you" "your" "yours" Sg P2 human ; -- verb agr OK
--  pronHe = mkPronoun "he" "him" "his" "his" Sg P3 Masc ;
--  pronShe = mkPronoun "she" "her" "her" "hers" Sg P3 Fem ;
--  pronIt = mkPronoun "it" "it" "its" "it" Sg P3 Neutr ;
--
--  pronWe = mkPronoun "we" "us" "our" "ours" Pl P1 human ;
--  pronYouPl = mkPronoun "you" "you" "your" "yours" Pl P2 human ;
--  pronThey = mkPronoun "they" "them" "their" "theirs" Pl P3 human ; ---
--
--
----2 Adjectives
----
---- To form the adjectival and the adverbial forms, two strings are needed
---- in the worst case. (First without degrees.)
--
--  Adjective = {s : AForm => Str} ;
--
---- However, most adjectives can be inflected using the final character.
---- N.B. this is not correct for "shy", but $mkAdjective$ has to be used.
--
--  regAdjective : Str -> Adjective = \free -> 
--    let 
--      e   = last free ;
--      fre = init free ;
--      freely = case e of {
--        "y" => fre + "ily" ;
--        _   => free + "ly"
--        } ;
--      fre = case e of {
--        "e" => fre ;
--        "y" => fre + "i" ;
--        _   => free
--        }
--    in 
--    mkAdjective free (fre + "er") (fre + "est") freely ; 
--
---- Many adjectives are 'inflected' by adding a comparison word.
--
--  adjDegrLong : Str -> Adjective = \ridiculous ->
--    mkAdjective 
--      ridiculous 
--      ("more" ++ ridiculous) 
--      ("most" ++ ridiculous) 
--      ((regAdjective ridiculous).s ! AAdv) ;
--
--
----3 Verbs
----
---- The worst case needs five forms. (The verb "be" is treated separately.)
--
--  mkVerb4 : (_,_,_,_: Str) -> Verb = \go,goes,went,gone -> 
--    let going = case last go of {
--      "e" => init go + "ing" ;
--      _ => go + "ing"
--      }
--    in
--    mkVerb go goes went gone going ;
--
---- This is what we use to derive the irregular forms in almost all cases
--
--  mkVerbIrreg : (_,_,_ : Str) -> Verb = \bite,bit,bitten -> 
--    let bites = case last bite of {
--      "y" => y2ie bite "s" ;
--      "s" => init bite + "es" ;
--      _   => bite + "s"
--      } 
--    in mkVerb4 bite bites bit bitten ;
--
---- This is used to derive regular forms.
--
--  mkVerbReg : Str -> Verb = \soak -> 
--    let 
--      soaks = case last soak of {
--        "y" => y2ie soak "s" ;
--        "s" => init soak + "es" ;
--        _   => soak + "s"
--        } ;
--      soaked = case last soak of {
--        "e" => init soak + "s" ;
--        _   => soak + "ed"
--        }
--    in 
--    mkVerb4 soak soaks soaked soaked ;
--
--  verbGen : Str -> Verb = \kill -> case last kill of {
--    "y" => verbP3y (init kill) ;
--    "e" => verbP3e (init kill) ;
--    "s" => verbP3s (init kill) ;
--    _   => regVerbP3 kill
--    } ;
--
---- These are just auxiliary to $verbGen$.
--
--  regVerbP3 : Str -> Verb = \walk -> 
--    mkVerbIrreg walk (walk + "ed") (walk + "ed") ;
--  verbP3s   : Str -> Verb = \kiss -> 
--    mkVerb4 kiss (kiss + "es") (kiss + "ed") (kiss + "ed") ;
--  verbP3e   : Str -> Verb = \love -> 
--    mkVerb4 love (love + "s") (love + "d") (love + "d") ;
--  verbP3y   : Str -> Verb = \cr -> 
--    mkVerb4 (cr + "y") (cr + "ies") (cr + "ied") (cr + "ied") ;
--
----- The particle always appears right after the verb.
--
--  verbPart : Verb -> Str -> Verb = \v,p ->
--    {s = \\f => v.s ! f ++ p ; isRefl = v.isRefl} ;
--
--  verbNoPart : Verb -> Verb = \v -> verbPart v [] ;
--
--
--} ;
