----1 Thai Lexical Paradigms
----
---- Aarne Ranta 2003--2005
----
---- This is an API for the user of the resource grammar
---- for adding lexical items. It gives functions for forming
---- expressions of open categories: nouns, adjectives, verbs.
----
---- Closed categories (determiners, pronouns, conjunctions) are
---- accessed through the resource syntax API, $Structural.gf$.
----
---- The main difference with $MorphoTha.gf$ 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 structure of functions for each word class $C$ is the following:
---- first we give a handful of patterns that aim to cover all
---- regular cases. Then we give a worst-case function $mkC$, which serves as an
---- escape to construct the most irregular words of type $C$.
---- However, this function should only seldom be needed: we have a
---- separate module [``IrregTha`` ../../english/IrregTha.gf],
---- which covers irregular verbss.

----2 Parameters
----
---- To abstract over gender names, we define the following identifiers.
--
--oper
-- Gender : Type ;
--
-- human : Gender ;
-- nonhuman : Gender ;
-- masculine : 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 ;
--
---- Prepositions are used in many-argument functions for rection.
---- The resource category $Prep$ is used.
--
--
--
----2 Nouns
--
---- Nouns are constructed by the function $mkN$, which takes a varying
---- number of arguments.
--
-- mkN : overload {
--
---- Worst case: give all four forms.
--
-- mkN : (man,men,man's,men's : Str) -> N ;
--
---- The regular function captures the variants for nouns ending with
---- "s","sh","x","z" or "y": "kiss - kisses", "flash - flashes";
---- "fly - flies" (but "toy - toys"),
--
-- mkN : (flash : Str) -> N ;
--
---- In practice the worst case is just: give singular and plural nominative.
--
-- mkN : (man,men : Str) -> N ;
--
---- All nouns created by the previous functions are marked as
---- $nonhuman$. If you want a $human$ noun, wrap it with the following
---- function:
--
-- mkN : Gender -> N -> N ;
--
----3 Compound nouns
----
---- A compound noun is an uninflected string attached to an inflected noun,
---- such as "baby boom", "chief executive officer".
--
-- mkN : Str -> N -> N
-- } ;
--
--
----3 Relational nouns
----
---- Relational nouns ("daughter of x") need a preposition.
--
-- mkN2 : N -> Prep -> N2 ;
--
---- The most common preposition is "of", and the following is a
---- shortcut for regular relational nouns with "of".
--
-- regN2 : Str -> N2 ;
--
---- Use the function $mkPrep$ or see the section on prepositions below to
---- form other prepositions.
----
---- Three-place relational nouns ("the connection from x to y") need two prepositions.
--
-- mkN3 : N -> Prep -> Prep -> 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").
--
-- cnN2 : CN -> Prep -> N2 ;
-- cnN3 : CN -> Prep -> Prep -> N3 ;
--
----
----3 Proper names and noun phrases
----
---- Proper names, with a regular genitive, are formed as follows
--
-- regPN : Str -> PN ;
-- regGenPN : Str -> Gender -> PN ; -- John, John's
--
---- Sometimes you can reuse a common noun as a proper name, e.g. "Bank".
--
-- nounPN : N -> PN ;
--
---- To form a noun phrase that can also be plural and have an irregular
---- genitive, you can use the worst-case function.
--
-- mkNP : Str -> Str -> Number -> Gender -> NP ;
--
----2 Adjectives
--
---- Non-comparison one-place adjectives need two forms: one for
---- the adjectival and one for the adverbial form ("free - freely")
--
-- mkA : (free,freely : Str) -> A ;
--
---- For regular adjectives, the adverbial form is derived. This holds
---- even for cases with the variation "happy - happily".
--
-- regA : Str -> A ;
--
----3 Two-place adjectives
----
---- Two-place adjectives need a preposition for their second argument.
--
-- mkA2 : A -> Prep -> A2 ;
--
---- Comparison adjectives may two more forms.
--
-- ADeg : Type ;
--
-- mkADeg : (good,better,best,well : Str) -> ADeg ;
--
---- The regular pattern recognizes two common variations:
---- "-e" ("rude" - "ruder" - "rudest") and
---- "-y" ("happy - happier - happiest - happily")
--
-- regADeg : Str -> ADeg ; -- long, longer, longest
--
---- However, the duplication of the final consonant is nor predicted,
---- but a separate pattern is used:
--
-- duplADeg : Str -> ADeg ; -- fat, fatter, fattest
--
---- If comparison is formed by "more", "most", as in general for
---- long adjective, the following pattern is used:
--
-- compoundADeg : A -> ADeg ; -- -/more/most ridiculous
--
---- From a given $ADeg$, it is possible to get back to $A$.
--
-- adegA : ADeg -> A ;
--
--
----2 Adverbs
--
---- Adverbs are not inflected. Most lexical ones have position
---- after the verb. Some can be preverbal (e.g. "always").
--
-- mkAdv : Str -> Adv ;
-- mkAdV : Str -> AdV ;
--
---- Adverbs modifying adjectives and sentences can also be formed.
--
-- mkAdA : Str -> AdA ;
--
----2 Prepositions
----
---- A preposition as used for rection in the lexicon, as well as to
---- build $PP$s in the resource API, just requires a string.
--
-- mkPrep : Str -> Prep ;
-- noPrep : Prep ;
--
---- (These two functions are synonyms.)
--
----2 Verbs
----
---- Except for "be", the worst case needs five forms: the infinitive and
---- the third person singular present, the past indicative, and the
---- past and present participles.
--
-- mkV : (go, goes, went, gone, going : Str) -> V ;
--
---- The regular verb function recognizes the special cases where the last
---- character is "y" ("cry - cries" but "buy - buys") or "s", "sh", "x", "z"
---- ("fix - fixes", etc).
--
-- regV : Str -> V ;
--
---- The following variant duplicates the last letter in the forms like
---- "rip - ripped - ripping".
--
-- regDuplV : Str -> V ;
--
---- There is an extensive list of irregular verbs in the module $IrregularTha$.
---- In practice, it is enough to give three forms,
---- e.g. "drink - drank - drunk", with a variant indicating consonant
---- duplication in the present participle.
--
-- irregV : (drink, drank, drunk : Str) -> V ;
-- irregDuplV : (get, got, gotten : Str) -> V ;
--
--
----3 Verbs with a particle.
----
---- The particle, such as in "switch on", is given as a string.
--
-- partV : V -> Str -> V ;
--
----3 Reflexive verbs
----
---- By default, verbs are not reflexive; this function makes them that.
--
-- reflV : V -> 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 -> Prep -> V2 ;
--
-- dirV2 : V -> V2 ;
--
----3 Three-place verbs
----
---- Three-place (ditransitive) verbs need two prepositions, of which
---- the first one or both can be absent.
--
-- mkV3 : V -> Prep -> Prep -> V3 ; -- speak, with, about
-- dirV3 : V -> Prep -> V3 ; -- give,_,to
-- dirdirV3 : V -> V3 ; -- give,_,_
--
----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 -> Prep -> V2S ;
-- mkVV : V -> VV ;
-- mkV2V : V -> Prep -> Prep -> V2V ;
-- mkVA : V -> VA ;
-- mkV2A : V -> Prep -> V2A ;
-- mkVQ : V -> VQ ;
-- mkV2Q : V -> Prep -> V2Q ;
--
-- mkAS : A -> AS ;
-- mkA2S : A -> Prep -> A2S ;
-- mkAV : A -> AV ;
-- mkA2V : A -> Prep -> A2V ;
--
---- Notice: categories $V2S, V2V, V2A, V2Q$ are in v 1.0 treated
---- just as synonyms of $V2$, and the second argument is given
---- as an adverb. Likewise $AS, A2S, AV, A2V$ are just $A$.
---- $V0$ is just $V$.
--
-- V0, V2S, V2V, V2A, V2Q : Type ;
-- AS, A2S, AV, A2V : Type ;
