+--1 English Lexical Paradigms

+-- Closed categories (determiners, pronouns, conjunctions) are

+--2 Adjectives
+--

+
+--3 Comparison adjectives
+--
+-- Each of the comparison forms has a characteristic use:
+--
+-- Positive forms are used alone, as adjectival phrases ("big").
+
+  positAdjPhrase : AdjDegr -> AdjPhrase = \big -> 
+    adj2adjPhrase (ss (big.s ! Pos)) ;

+-- Comparative forms are used with an object of comparison, as

+     n = Sg ;

+  AdjCompl = Adjective ** {s2 : Preposition} ;
+
+  complAdj : AdjCompl -> NounPhrase -> AdjPhrase = \related,john ->
+    {s = related.s ++ related.s2 ++ john.s ! AccP ; 
+     p = False
+    } ;
+
+
+--3 Modification of common nouns
+--
+-- The two main functions of adjective are in predication ("John is old")
+-- and in modification ("an old man"). Predication will be defined
+-- later, in the chapter on verbs.
+--
+-- Modification must pay attention to pre- and post-noun
+-- adjectives: "big car"/"car bigger than X"
+
+  modCommNounPhrase : AdjPhrase -> CommNounPhrase -> CommNounPhrase = \big, car -> 
+    {s = \\n => if_then_else (Case => Str) big.p

+     g = car.g
+    } ;
+
+
+--2 Function expressions
+
+-- A function expression is a common noun together with the
+-- preposition prefixed to its argument ("mother of x").
+-- The type is analogous to two-place adjectives and transitive verbs.
+
+  Function = CommNounPhrase ** {s2 : Preposition} ;
+
+-- The application of a function gives, in the first place, a common noun:
+-- "mother/mothers of John". From this, other rules of the resource grammar 
+-- give noun phrases, such as "the mother of John", "the mothers of John",
+-- "the mothers of John and Mary", and "the mother of John and Mary" (the
+-- latter two corresponding to distributive and collective functions,
+-- respectively). Semantics will eventually tell when each
+-- of the readings is meaningful.
+
+  appFunComm : Function -> NounPhrase -> CommNounPhrase = \mother,john -> 
+    {s = \\n => table {
+            Gen => nonExist ;
+            _ => mother.s ! n ! Nom ++ mother.s2 ++ john.s ! GenSP 
+            } ;
+     g = mother.g
+    } ;
+
+-- It is possible to use a function word as a common noun; the semantics is
+-- often existential or indexical.
+
+  funAsCommNounPhrase : Function -> CommNounPhrase = 
+    noun2CommNounPhrase ;
+
+-- The following is an aggregate corresponding to the original function application
+-- producing "John's mother" and "the mother of John". It does not appear in the
+-- resource grammar API any longer.
+
+  appFun : Bool -> Function -> NounPhrase -> NounPhrase = \coll, mother,john -> 
+    let {n = john.n ; nf = if_then_else Number coll Sg n} in 
+    variants {
+      defNounPhrase nf (appFunComm mother john) ;
+      npGenDet nf john mother
+      } ;      
+
+-- The commonest case is functions with the preposition  "of".
+
+  funOf : CommNoun -> Function = \mother -> 
+    mother ** {s2 = "of"} ;
+
+  funOfReg : Str -> Gender -> Function = \mother,g -> 
+    funOf (nounReg mother ** {g = g}) ;
+
+
+
+--2 Verbs
+--
+--3 Verb phrases
+--
+-- Verb phrases are discontinuous: the two parts of a verb phrase are
+-- (s) an inflected verb, (s2) infinitive and complement.
+-- For instance: "doesn't" - "walk" ; "isn't" - "old" ; "is" - "a man"
+-- There's also a parameter telling if the verb is an auxiliary:
+-- this is needed in question.
+
+  VerbPhrase = VerbP3 ** {s2 : Number => Str ; isAux : Bool} ;
+
+-- From the inflection table, we selecting the finite form as function 
+-- of person and number:
+
+  indicVerb : VerbP3 -> Person -> Number -> Str = \v,p,n -> case n of {
+    Sg => v.s ! Indic p ;
+    Pl => v.s ! Indic P2
+    } ;
+
+-- A simple verb can be made into a verb phrase with an empty complement.
+-- There are two versions, depending on if we want to negate the verb.
+-- N.B. negation is *not* a function applicable to a verb phrase, since
+-- double negations with "don't" are not grammatical.
+
+  predVerb : Bool -> Verb -> VerbPhrase = \b,walk ->
+    if_then_else VerbPhrase b 
+      {s = \\v => walk.s ! v ++ walk.s1 ;
+       s2 = \\_ => [] ; 
+       isAux = False
+      }
+      {s  = \\v => contractNot (verbP3Do.s ! v) ; 
+       s2 = \\_ => walk.s ! InfImp ++ walk.s1 ;
+       isAux = True
+      } ;
+
+-- Sometimes we want to extract the verb part of a verb phrase.
+
+  verbOfPhrase : VerbPhrase -> VerbP3 = \v -> {s = v.s} ;
+
+-- Verb phrases can also be formed from adjectives ("is old"),
+-- common nouns ("is a man"), and noun phrases ("ist John").
+-- The third rule is overgenerating: "is every man" has to be ruled out
+-- on semantic grounds.
+
+  predAdjective : Bool -> Adjective -> VerbPhrase = \b,old ->
+    {s = beOrNotBe b ;
+     s2 = \\_ => old.s ;
+     isAux = True
+    } ;
+
+  predCommNoun : Bool -> CommNoun -> VerbPhrase = \b,man ->
+    {s = beOrNotBe b ;
+     s2 = \\n => indefNoun n man ;
+     isAux = True
+    } ;
+
+  predNounPhrase : Bool -> NounPhrase -> VerbPhrase = \b,john ->
+    {s = beOrNotBe b ;
+     s2 = \\_ => john.s ! NomP ;
+     isAux = True
+    } ;
+
+-- We use an auxiliary giving all forms of "be".
+
+  beOrNotBe : Bool -> (VForm => Str) = \b -> 
+    if_then_else (VForm => Str) b 
+      verbBe.s
+      (table {
+        InfImp   => contractNot "do" ++ "be" ;
+        Indic P1 => "am" ++ "not" ;
+        v        => contractNot (verbBe.s ! v)
+        }) ;
+
+--3 Transitive verbs
+--
+-- Transitive verbs are verbs with a preposition for the complement,
+-- in analogy with two-place adjectives and functions.
+-- One might prefer to use the term "2-place verb", since
+-- "transitive" traditionally means that the inherent preposition is empty.
+-- Such a verb is one with a *direct object*.
+
+  TransVerb : Type = Verb ** {s3 : Preposition} ;
+
+-- The rule for using transitive verbs is the complementization rule.
+-- Particles produce free variation: before or after the complement 
+-- ("I switch on the TV" / "I switch the TV on").
+
+  complTransVerb : Bool -> TransVerb -> NounPhrase -> VerbPhrase = 
+    \b,lookat,john ->
+    let {lookatjohn = bothWays lookat.s1 (lookat.s3 ++ john.s ! AccP)} in
+    if_then_else VerbPhrase b 
+      {s = lookat.s ; 
+       s2 = \\_ => lookatjohn ; 
+       isAux = False}
+      {s = \\v => contractNot (verbP3Do.s ! v) ; 
+       s2 = \\_ => lookat.s ! InfImp ++ lookatjohn ;
+       isAux = True} ;
+
+
+-- Verbs that take direct object and a  particle:
+  mkTransVerbPart : VerbP3 -> Str -> TransVerb = \turn,off -> 
+    {s = turn.s ; s1 = off ; s3 = []} ;
+
+-- Verbs that take prepositional object, no particle:
+  mkTransVerb : VerbP3 -> Str -> TransVerb = \wait,for -> 
+    {s = wait.s ; s1 = [] ; s3 = for} ;
+
+-- Verbs that take direct object, no particle:
+  mkTransVerbDir : VerbP3 -> TransVerb = \love -> 
+    mkTransVerbPart love [] ;
+
+
+--2 Adverbials
+--
+-- Adverbials are not inflected (we ignore comparison, and treat
+-- compared adverbials as separate expressions; this could be done another way).
+-- We distinguish between post- and pre-verbal adverbs.
+
+  Adverb : Type = SS ** {isPost : Bool} ;
+
+  advPre  : Str -> Adverb = \seldom -> ss seldom ** {isPost = False} ;
+  advPost : Str -> Adverb = \well   -> ss well   ** {isPost = True} ;
+
+-- N.B. this rule generates the cyclic parsing rule $VP#2 ::= VP#2$
+-- and cannot thus be parsed.
+
+  adVerbPhrase : VerbPhrase -> Adverb -> VerbPhrase = \sings, well ->
+    let {postp = orB well.isPost sings.isAux} in
+    {
+     s = \\v => (if_then_else Str postp [] well.s) ++ sings.s ! v ;
+     s2 = \\n => sings.s2 ! n ++ (if_then_else Str postp well.s []) ;
+     isAux = sings.isAux
+    } ;
+
+-- Adverbials are typically generated by prefixing prepositions.
+-- The rule for creating locative noun phrases by the preposition "in"
+-- is a little shaky, since other prepositions may be preferred ("on", "at").
+
+  prepPhrase : Preposition -> NounPhrase -> Adverb = \on, it ->
+    advPost (on ++ it.s ! AccP) ;
+
+  locativeNounPhrase : NounPhrase -> Adverb = 
+    prepPhrase "in" ;
+
+-- This is a source of the "mann with a telescope" ambiguity, and may produce
+-- strange things, like "cars always" (while "cars today" is OK).
+-- Semantics will have to make finer distinctions among adverbials.
+--
+-- N.B. the genitive case created in this way would not make sense.
+
+  advCommNounPhrase : CommNounPhrase -> Adverb -> CommNounPhrase = \car,today ->
+   {s = \\n => table {
+      Nom => car.s ! n ! Nom ++ today.s ; 
+      Gen => nonExist
+      } ;
+    g = car.g
+   } ;
+
+
+--2 Sentences
+--
+-- Sentences are not inflected in this fragment of English without tense.
+
+  Sentence : Type = SS ;
+
+-- This is the traditional $S -> NP VP$ rule. It takes care of
+-- agreement between subject and verb. Recall that the VP may already
+-- contain negation. 
+
+  predVerbPhrase : NounPhrase -> VerbPhrase -> Sentence = \john,walks ->
+    ss (john.s ! NomP ++ indicVerb (verbOfPhrase walks) john.p john.n ++ 
+        walks.s2 ! john.n) ;
+
+
+-- This is a macro for simultaneous predication and complementization.
+
+  predTransVerb : Bool -> NounPhrase -> TransVerb -> NounPhrase -> Sentence = 
+    \b,you,see,john -> 
+    predVerbPhrase you (complTransVerb b see john) ;
+
+
+--3 Sentence-complement verbs
+--
+-- Sentence-complement verbs take sentences as complements.
+
+  SentenceVerb : Type = Verb ;
+
+-- To generate "says that John walks" / "doesn't say that John walks":
+
+  complSentVerb : Bool -> SentenceVerb -> Sentence -> VerbPhrase = 
+    \b,say,johnruns ->
+    let {thatjohnruns = optStr "that" ++ johnruns.s} in

+-- However, we need something more to distinguish its use in direct questions:
+-- not just "you see" but ("whom") "do you see".
+--
+-- The particle always follows the verb, but the preposition can fly:

+--2 Relative pronouns and relative clauses
+--
+-- As described in $types.Eng.gf$, relative pronouns are inflected in

+-- "number x such that x is even".
+
+  relSuch : Sentence -> RelClause = \A ->
+    {s = \\_,_ => "such" ++ "that" ++ A.s} ;
+

+
+-- By utterances we mean whole phrases, such as 
+-- 'can be used as moves in a language game': indicatives, questions, imperative,
+-- and one-word utterances. The rules are far from complete.
+--
+-- N.B. we have not included rules for texts, which we find we cannot say much
+-- about on this level. In semantically rich GF grammars, texts, dialogues, etc, 
+-- will of course play an important role as categories not reducible to utterances.
+-- An example is proof texts, whose semantics show a dependence between premises
+-- and conclusions. Another example is intersentential anaphora.
+
+  Utterance = SS ;

+-- and after interrogative adverbials 
+-- ("why does John walk" / "why John walks").
+-- 
+-- It is economical to handle with all these cases by the one
+-- rule, $questVerbPhrase'$. The word ("ob" / "whether") never appears

+--3 Interrogative adverbials
+--
+-- These adverbials will be defined in the lexicon: they include

+-- expressions. In addition, they can be formed by adding prepositions
+-- to interrogative pronouns, in the same way as adverbials are formed

+--2 Coordination
+--
+-- Coordination is to some extent orthogonal to the rest of syntax, and
+-- has been treated in a generic way in the module $CO$ in the file
+-- $coordination.gf$. The overall structure is independent of category,
+-- but there can be differences in parameter dependencies.
+--
+--3 Conjunctions
+--
+-- Coordinated phrases are built by using conjunctions, which are either
+-- simple ("and", "or") or distributed ("both - and", "either - or").
+--
+-- The conjunction has an inherent number, which is used when conjoining
+-- noun phrases: "John and Mary are..." vs. "John or Mary is..."; in the
+-- case of "or", the result is however plural if any of the disjuncts is.

+  Conjunction = CO.Conjunction ** {n : Number} ;

+
+--3 Coordinating sentences
+--
+-- We need a category of lists of sentences. It is a discontinuous
+-- category, the parts corresponding to 'init' and 'last' segments

+
+  conjunctSentence : Conjunction -> ListSentence -> Sentence = \c,xs ->
+    ss (CO.conjunctX c xs) ;
+
+-- To coordinate a list of sentences by a distributed conjunction, we place
+-- the first part (e.g. "either") in front of the first element, the second
+-- part ("or") between the last two elements, and commas in the other slots.
+-- For sentences this is really not used.
+
+  conjunctDistrSentence : ConjunctionDistr -> ListSentence -> Sentence = 
+    \c,xs ->
+    ss (CO.conjunctDistrX c xs) ;
+
+--3 Coordinating adjective phrases

+-- if and only if all elements are prefix.

+    ss (CO.conjunctDistrX c xs) ** {p = xs.p} ;
+
+
+--3 Coordinating noun phrases
+--
+-- The structure is the same as for sentences. The result is either always plural
+-- or plural if any of the components is, depending on the conjunction.
+
+  ListNounPhrase : Type = {s1,s2 : NPForm => Str ; n : Number ; p : Person} ;
+
+  twoNounPhrase : (_,_ : NounPhrase) -> ListNounPhrase = \x,y ->
+    CO.twoTable NPForm x y ** {n = conjNumber x.n y.n ; p = conjPerson x.p y.p} ;

+-- We have to define a calculus of numbers of persons. For numbers,
+-- it is like the conjunction with $Pl$ corresponding to $False$.

+  conjNumber : Number -> Number -> Number = \m,n -> case <m,n> of {
+    <Sg,Sg> => Sg ;
+    _ => Pl 
+    } ;
+
+-- For persons, we let the latter argument win ("either you or I am absent"
+-- but "either I or you are absent"). This is not quite clear.
+
+  conjPerson : Person -> Person -> Person = \_,p -> 
+    p ;
+
+
+
+--2 Subjunction
+--
+-- Subjunctions ("when", "if", etc) 
+-- are a different way to combine sentences than conjunctions.
+-- The main clause can be a sentences, an imperatives, or a question,
+-- but the subjoined clause must be a sentence.
+--
+-- There are uniformly two variant word orders, e.g. 
+-- "if you smoke I get angry"
+-- and "I get angry if you smoke".
+
+  Subjunction = SS ;
