------1 A Simple Teldi 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 $ParadigmsTel$, which
------ gives a higher-level access to this module.
----
--resource MorphoTel = ResTel ** 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} ;
----
----  mkPronoun : (_,_,_,_ : Str) -> Number -> Person -> Gender -> Pronoun = 
----   \I,me,my,mine,n,p,g -> 
----    {s = table {Nom => I ; Acc => me ; Gen => my} ; 
----     a = toAgr n p 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 [] ;
