-- 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 $MorphoFin.gf$ is that the types
-- referred to are compiled resource grammar types. We have moreover
-- had the design principle of always having existing forms, not
-- stems, as string arguments of the paradigms, not stems.

--2 Parameters
--
-- To abstract over gender, number, and (some) case names,
-- we define the following identifiers.
oper
Gender : Type;
human : Gender ;
nonhuman : Gender ;
Number : Type;
singular : Number ;
plural : Number ;
Case : Type ;
nominative : Case ;
genitive : Case ;
partitive : Case ;
inessive : Case ;
elative : Case ;
illative : Case ;
adessive : Case ;
ablative : Case ;
allative : Case ;
--2 Nouns
-- Worst case: give ten forms and the semantic gender.
-- In practice just a couple of forms are needed, to define the different
-- stems, vowel alternation, and vowel harmony.
oper
mkN :
(talo,talon,talona,taloa,taloon,taloina,taloissa,talojen,taloja,taloihin
: Str) -> Gender -> N ;
-- The regular noun heuristic takes just one form and analyses its suffixes.
oper
regN : (talo : Str) -> N ;
regNoun : (talo : Str) -> CommonNoun ;
-- Nouns with partitive "a"/"ä" are a large group.
-- To determine for grade and vowel alternation, three forms are usually needed:
-- singular nominative and genitive, and plural partitive.
-- Examples: "talo", "kukko", "huippu", "koira", "kukka", "syylä", "särki"...
regVerb : (soutaa : Str) -> Verb ;
nKukko : (kukko,kukon,kukkoja : Str) -> N ;
-- For convenience, we define 1-argument paradigms as producing the
-- nonhuman gender; the following function changes this:
humanN : N -> N ;
-- A special case are nouns with no alternations:
-- the vowel harmony is inferred from the last letter,
-- which must be one of "o", "u", "ö", "y".
nTalo : (talo : Str) -> N ;
-- Another special case are nouns where the last two consonants
-- undergo regular weak-grade alternation:
-- "kukko - kukon", "rutto - ruton", "hyppy - hypyn", "sampo - sammon",
-- "kunto - kunnon", "sisältö - sisällön", .
nLukko : (lukko : Str) -> N ;
-- "arpi - arven", "sappi - sapen", "kampi - kammen";"sylki - syljen"
nArpi : (arpi : Str) -> N ;
nSylki : (sylki : Str) -> N ;
-- Foreign words ending in consonants are actually similar to words like
-- "malli"/"mallin"/"malleja", with the exception that the "i" is not attached
-- to the singular nominative. Examples: "linux", "savett", "screen".
-- The singular partitive form is used to get the vowel harmony. (N.B. more than
-- 1-syllabic words ending in "n" would have variant plural genitive and
-- partitive forms, like "sultanien"/"sultaneiden", which are not covered.)
nLinux : (linuxia : Str) -> N ;
-- Nouns of at least 3 syllables ending with "a" or "ä", like "peruna", "tavara",
-- "rytinä".
nPeruna : (peruna : Str) -> N ;
-- The following paradigm covers both nouns ending in an aspirated "e", such as
-- "rae", "perhe", "savuke", and also many ones ending in a consonant
-- ("rengas", "kätkyt"). The singular nominative and essive are given.
nRae : (rae, rakeena : Str) -> N ;
-- The following covers nouns with partitive "ta"/"tä", such as
-- "susi", "vesi", "pieni". To get all stems and the vowel harmony, it takes
-- the singular nominative, genitive, and essive.
nSusi : (susi,suden,sutta : Str) -> N ;
-- Nouns ending with a long vowel, such as "puu", "pää", "pii", "leikkuu",
-- are inflected according to the following.
nPuu : (puu : Str) -> N ;
-- One-syllable diphthong nouns, such as "suo", "tie", "työ", are inflected by
-- the following.
nSuo : (suo : Str) -> N ;
-- Many adjectives but also nouns have the nominative ending "nen" which in other
-- cases becomes "s": "nainen", "ihminen", "keltainen".
-- To capture the vowel harmony, we use the partitive form as the argument.
nNainen : (naista : Str) -> N ;
-- The following covers some nouns ending with a consonant, e.g.
-- "tilaus", "kaulin", "paimen", "laidun".
nTilaus : (tilaus,tilauksena : Str) -> N ;
-- Special case:
nKulaus : (kulaus : Str) -> N ;
-- The following covers nouns like "nauris" and adjectives like "kallis", "tyyris".
-- The partitive form is taken to get the vowel harmony.
nNauris : (naurista : Str) -> N ;
-- Separately-written compound nouns, like "sambal oelek", "Urho Kekkonen",
-- have only their last part inflected.
nComp : Str -> N -> N ;
-- Nouns used as functions need a case, of which by far the commonest is
-- the genitive.
mkN2 : N -> Case -> N2 ;
fGen : N -> N2 ;
-- Proper names can be formed by using declensions for nouns.
-- The plural forms are filtered away by the compiler.
mkPN : N -> PN ;
--2 Adjectives
-- Non-comparison one-place adjectives are just like nouns.
mkA : N -> A ;
-- Two-place adjectives need a case for the second argument.
mkA2 : N -> Case -> A2 ;
-- Comparison adjectives have three forms. The comparative and the superlative
-- are always inflected in the same way, so the nominative of them is actually
-- enough (except for the superlative "paras" of "hyvä").
mkADeg : (kiva : N) -> (kivempaa,kivinta : Str) -> ADeg ;
--2 Verbs
--
-- The fragment only has present tense so far, but in all persons.
-- The worst case needs five forms, as shown in the following.
mkV : (tulla,tulee,tulen,tulevat,tulkaa,tullaan,
tuli,tulin,tulisi,tullut,tultu,tullun : Str) -> V ;
regV : (soutaa : Str) -> V ;
-- A simple special case is the one with just one stem and no grade alternation.
-- It covers e.g. "sanoa", "valua", "kysyä".
vValua : (valua : Str) -> V ;
-- With two forms, the following function covers a variety of verbs, such as
-- "ottaa", "käyttää", "löytää", "huoltaa", "hiihtää", "siirtää".
vKattaa : (kattaa, katan : Str) -> V ;
-- When grade alternation is not present, just a one-form special case is needed
-- ("poistaa", "ryystää").
vOstaa : (ostaa : Str) -> V ;
-- The following covers
-- "juosta", "piestä", "nousta", "rangaista", "kävellä", "surra", "panna".
vNousta : (nousta, nousen : Str) -> V ;
-- This is for one-syllable diphthong verbs like "juoda", "syödä".
vTuoda : (tuoda : Str) -> V ;
-- The verbs "be" and the negative auxiliary are special.
vOlla : V ;
vEi : V ;
-- Two-place verbs need a case, and can have a pre- or postposition.
-- At least one of the latter is empty, $[]$.
mkV2 : V -> Case -> (prep,postp : Str) -> V2 ;
-- If both are empty, the following special function can be used.
tvCase : V -> Case -> V2 ;
-- Verbs with a direct (accusative) object
-- are special, since their complement case is finally decided in syntax.

--1 Finnish Lexical Paradigms
--
-- Aarne Ranta 2005
--
-- 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, $resource.Abs.gf$.
--
-- The main difference with $MorphoIta.gf$ is that the types
-- referred to are compiled resource grammar types. We have moreover
-- had the design principle of always having existing forms, not stems, as string
-- arguments of the paradigms.
--
-- The following modules are presupposed:
resource ParadigmsSpa =
open Prelude, (Types = TypesSpa), SyntaxSpa, MorphoSpa, BeschSpa,
RulesSpa in {
--2 Parameters
--
-- To abstract over gender names, we define the following identifiers.
oper
Bool : Type ;
Gender : Type ;
masculine : Gender ;
feminine : Gender ;
-- To abstract over number names, we define the following.
Number : Type ;
singular : Number ;
plural : Number ;
-- Prepositions used in many-argument functions are either strings
-- (including the 'accusative' empty string) or strings that
-- amalgamate with the following word (the 'genitive' "de" and the
-- 'dative' "à").
Preposition : Type ;
accusative : Preposition ;
dative : Preposition ;
genitive : Preposition ;
mkPreposition : Str -> Preposition ;
--2 Nouns
-- Worst case: ten forms.
mkN : (talo,talon,talona,taloa,taloon,taloina,
taloissa,talojen,taloja,taloihin : Str) -> N ;
-- The regular heuristic analyses the singular nominative form. It works for the
-- following types of nouns: "maa/tee/pii/tienoo/puu/pyy/pää/köö",
-- "tie/suo/työ", "nauris", "rae/perhe/hake/...", "ihanuus/itsekkyys",
-- "tilaus/lisäys","baari", "nauris", "talo/hyppy/..." and takes care
-- of grade and vowel alternations.
regN : (talo : Str) -> N ;
-- The almost-regular heuristic analyses three forms. It works for the
-- following classes: ...
reg3N : (vesi,veden,vesiä : Str) -> N ;
-- The regular function takes the singular form and the gender,
-- and computes the plural and the gender by a heuristic.
-- The heuristic says that the gender is feminine for nouns
-- ending with "a" or "z", and masculine for all other words.
-- Nouns ending with "a", "o", "e" have the plural with "s",
-- those ending with "z" have "ces" in plural; all other nouns
-- have "es" as plural ending. The accent is not dealt with.
regN : Str -> N ;
-- To force a different gender, use one of the following functions.
mascN : N -> N ;
femN : N -> N ;
--3 Compound nouns
--
-- Some nouns are ones where the first part is inflected as a noun but
-- the second part is not inflected. e.g. "numéro de téléphone".
-- They could be formed in syntax, but we give a shortcut here since
-- they are frequent in lexica.
compN : N -> Str -> N ;
--3 Relational nouns
--
-- Relational nouns ("fille de x") need a case and a preposition.
mkN2 : N -> Preposition -> N2 ;
-- The most common cases are the genitive "de" and the dative "a",
-- with the empty preposition.
deN2 : N -> N2 ;
aN2 : N -> N2 ;
-- Three-place relational nouns ("la connessione di x a y") need two prepositions.
mkN3 : N -> Preposition -> Preposition -> N3 ;
--3 Relational common noun phrases
--
-- In some cases, you may want to make a complex $CN$ into a
-- relational noun (e.g. "the old town hall of"). However, $N2$ and
-- $N3$ are purely lexical categories. But you can use the $AdvCN$
-- and $PrepNP$ constructions to build phrases like this.
--
--3 Proper names and noun phrases
--
-- Proper names need a string and a gender.
mkPN : Str -> Gender -> PN ; -- Jean
-- To form a noun phrase that can also be plural,
-- you can use the worst-case function.
mkNP : Str -> Gender -> Number -> NP ;
--2 Adjectives
-- Non-comparison one-place adjectives need five forms in the worst
-- case (masc and fem singular, masc plural, adverbial).
mkA : (solo,sola,soli,sole, solamente : Str) -> A ;
-- For regular adjectives, all other forms are derived from the
-- masculine singular. The types of adjectives that are recognized are
-- "alto", "fuerte", "util".
regA : Str -> A ;
-- These functions create postfix adjectives. To switch
-- them to prefix ones (i.e. ones placed before the noun in
-- modification, as in "petite maison"), the following function is
-- provided.
prefA : A -> A ;
--3 Two-place adjectives
--
-- Two-place adjectives need a preposition for their second argument.
mkA2 : A -> Preposition -> A2 ;
--3 Comparison adjectives
-- Comparison adjectives are in the worst case put up from two
-- adjectives: the positive ("bueno"), and the comparative ("mejor").
mkADeg : A -> A -> ADeg ;
-- If comparison is formed by "mas", as usual in Spanish,
-- the following pattern is used:
compADeg : A -> ADeg ;
-- The regular pattern is the same as $regA$ for plain adjectives,
-- with comparison by "mas".
regADeg : Str -> ADeg ;
-- From a given $ADeg$, it is possible to get back to $A$.
adegA : ADeg -> A ;
-- For prefixed adjectives, the following function is
-- provided.
prefADeg : ADeg -> ADeg ;
--2 Adverbs
-- Adverbs are not inflected. Most lexical ones have position
-- after the verb.
mkAdv : Str -> Adv ;
-- Some appear next to the verb (e.g. "siempre").
mkAdV : Str -> AdV ;
-- Adverbs modifying adjectives and sentences can also be formed.
mkAdA : Str -> AdA ;
--2 Verbs
--
-- Regular verbs are ones inflected like "cortar", "deber", or "vivir".
-- The regular verb function is the first conjugation ("ar") recognizes
-- the variations corresponding to the patterns
-- "actuar, cazar, guiar, pagar, sacar". The module $BeschSpa$ gives
-- the complete set of "Bescherelle" conjugations.
regV : Str -> V ;
-- The module $BeschSpa$ gives all the patterns of the "Bescherelle"
-- book. To use them in the category $V$, wrap them with the function
verboV : Verbum -> V ;
-- Verbs with a deviant passive participle: just give the participle
-- in masculine singular form as second argument.
special_ppV : V -> Str -> V ;
--3 Two-place verbs
--
-- Two-place verbs need a preposition, except the special case with direct object.
-- (transitive verbs). Notice that a particle comes from the $V$.
mkV2 : V -> Preposition -> V2 ;
dirV2 : V -> V2 ;
-- You can reuse a $V2$ verb in $V$.
v2V : V2 -> V ;
--3 Three-place verbs
--
-- Three-place (ditransitive) verbs need two prepositions, of which
-- the first one or both can be absent.
mkV3 : V -> Preposition -> Preposition -> V3 ; -- parler, à, de
dirV3 : V -> Preposition -> V3 ; -- donner,_,à
dirdirV3 : V -> V3 ; -- donner,_,_
--3 Other complement patterns
--
-- Verbs and adjectives can take complements such as sentences,
-- questions, verb phrases, and adjectives.
mkV0 : V -> V0 ;
mkVS : V -> VS ;
mkV2S : V -> Preposition -> V2S ;
mkVV : V -> VV ; -- plain infinitive: "je veux parler"
deVV : V -> VV ; -- "j'essaie de parler"
aVV : V -> VV ; -- "j'arrive à parler"
mkV2V : V -> Preposition -> Preposition -> V2V ;
mkVA : V -> VA ;
mkV2A : V -> Preposition -> V2A ;
mkVQ : V -> VQ ;
mkV2Q : V -> Preposition -> V2Q ;
mkAS : A -> AS ;
