--1 English Lexical Paradigms
--
-- Aarne Ranta 2003
--
-- This is an API to the user of the resource grammar
-- for adding lexical items. It give shortcuts for forming
-- expressions of basic categories: nouns, adjectives, verbs.
--
-- Closed categories (determiners, pronouns, conjunctions) are
-- accessed through the resource syntax API, $Structural.gf$.
--
-- The main difference with $MorphoEng.gf$ 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 following modules are presupposed:
resource OldParadigmsEng = open (Predef=Predef), Prelude, SyntaxEng, ResourceEng in {
--2 Parameters
--
-- To abstract over gender names, we define the following identifiers.
oper
Gender : Type ;
human : Gender ;
nonhuman : Gender ;
-- To abstract over number names, we define the following.
Number : Type ;
singular : Number ;
plural : Number ;
-- To abstract over case names, we define the following.
Case : Type ;
nominative : Case ;
genitive : Case ;
--2 Nouns
-- Worst case: give all four forms and the semantic gender.
-- In practice the worst case is just: give singular and plural nominative.
oper
mkN : (man,men,man's,men's : Str) -> Gender -> N ;
nMan : (man,men : Str) -> Gender -> N ;
-- Regular nouns, nouns ending with "s", "y", or "o", and nouns with the same
-- plural form as the singular.
nReg : Str -> Gender -> N ; -- dog, dogs
nKiss : Str -> Gender -> N ; -- kiss, kisses
nFly : Str -> Gender -> N ; -- fly, flies
nHero : Str -> Gender -> N ; -- hero, heroes (= nKiss !)
nSheep : Str -> Gender -> N ; -- sheep, sheep
-- These use general heuristics, that recognizes the last letter. *N.B* it
-- does not get right with "boy", "rush", since it only looks at one letter.
nHuman : Str -> N ; -- gambler/actress/nanny
nNonhuman : Str -> N ; -- dog/kiss/fly
-- Nouns used as functions need a preposition. The most common is "of".
mkN2 : N -> Preposition -> N2 ;
funHuman : Str -> N2 ; -- the father/mistress/daddy of
funNonhuman : Str -> N2 ; -- the successor/address/copy of
-- Proper names, with their regular genitive.
pnReg : (John : Str) -> PN ; -- John, John's
-- The most common cases on the higher-level category $CN$ have shortcuts.
-- The regular "y"/"s" variation is taken into account.
cnNonhuman : Str -> CN ;
cnHuman : Str -> CN ;
npReg : Str -> NP ;
-- In some cases, you may want to make a complex $CN$ into a function.
mkN2CN : CN -> Preposition -> N2 ;
funOfCN : CN -> N2 ;
--2 Adjectives
-- Non-comparison one-place adjectives just have one form.
mkA : (even : Str) -> A ;
-- Two-place adjectives need a preposition as second argument.
mkA2 : (divisible, by : Str) -> A2 ;
-- Comparison adjectives have three forms. The common irregular
-- cases are ones ending with "y" and a consonant that is duplicated;
-- the "y" ending is recognized by the function $aReg$.
mkADeg : (good,better,best : Str) -> ADeg ;
aReg : (long : Str) -> ADeg ; -- long, longer, longest
aFat : (fat : Str) -> ADeg ; -- fat, fatter, fattest
aRidiculous : (ridiculous : Str) -> ADeg ; -- -/more/most ridiculous
-- On higher level, there are adjectival phrases. The most common case is
-- just to use a one-place adjective.
apReg : Str -> AP ;
--2 Adverbs
-- Adverbs are not inflected. Most lexical ones have position not
-- before the verb. Some can be preverbal (e.g. "always").
mkAdv : Str -> Adv ;
mkAdvPre : Str -> Adv ;
-- Adverbs modifying adjectives and sentences can also be formed.
mkAdA : Str -> AdA ;
mkAdC : Str -> AdC ;
-- Prepositional phrases are another productive form of adverbials.
mkPP : Str -> NP -> Adv ;
--2 Verbs
--
-- The fragment now has all verb forms, except the gerund/present participle.
-- Except for "be", the worst case needs four forms: the infinitive and
-- the third person singular present, the past indicative, and the past participle.
mkV : (go, goes, went, gone : Str) -> V ;
vReg : (walk : Str) -> V ; -- walk, walks
vKiss : (kiss : Str) -> V ; -- kiss, kisses
vFly : (fly : Str) -> V ; -- fly, flies
vGo : (go : Str) -> V ; -- go, goes (= vKiss !)
-- This generic function recognizes the special cases where the last
-- character is "y", "s", or "z". It is not right for "finish" and "convey".
vGen : Str -> V ; -- walk/kiss/fly
-- The verbs "be" and "have" are special.
---- vBe : V ;
vHave : V ;
-- Verbs with a particle.
vPart : (go, goes, went, gone, up : Str) -> V ;
vPartReg : (get, up : Str) -> V ;
-- Two-place verbs, and the special case with direct object.
-- Notice that a particle can already be included in $V$.
mkV2 : V -> Str -> V2 ; -- look for, kill
tvGen : (look, for : Str) -> V2 ; -- look for, talk about
tvDir : V -> V2 ; -- switch off
tvGenDir : (kill : Str) -> V2 ; -- kill
-- Regular two-place verbs with a particle.
tvPartReg : Str -> Str -> Str -> V2 ; -- get, along, with
-- Ditransitive verbs.
mkV3 : V -> Str -> Str -> V3 ; -- speak, with, about
v3Dir : V -> Str -> V3 ; -- give,_,to
v3DirDir : V -> V3 ; -- give,_,_
-- The definitions should not bother the user of the API. So they are
-- hidden from the document.
