----1 A Simple Urdu Resource Morphology
|
||||
----
|
||||
---- Aarne Ranta, Shafqat Virk 2009
|
||||
----
|
||||
---- This resource morphology contains definitions needed in the resource
|
||||
---- syntax. To build a lexicon, it is better to use $ParadigmsHin$, which
|
||||
---- gives a higher-level access to this module.

----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 ;
|
||||

||||

|
||||
----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 ;
|
||||

||||

||||
-- "y" => fre + "ily" ;

||||

||||
-- "e" => fre ;

||||
-- }
|
||||
-- in

||||

|
||||
--
|
||||
--
|
||||
----3 Verbs
|
||||
----
|
||||
---- The worst case needs five forms. (The verb "be" is treated separately.)
|
||||
--
|
||||
-- mkVerb4 : (_,_,_,_: Str) -> Verb = \go,goes,went,gone ->
