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 structure of functions for each word class C
is the following:
first we give a handful of patterns that aim to cover all
cases, from the most regular (with just one argument) to the worst.
The name of this function is mkC
.
There is also a module IrregGer
which covers irregular verbs.
resource ParadigmsGer = open (Predef=Predef), Prelude, MorphoGer, CatGer in {
To abstract over gender names, we define the following identifiers.
oper Gender : Type ; masculine : Gender ; feminine : Gender ; neuter : Gender ;
To abstract over case names, we define the following.
Case : Type ; nominative : Case ; accusative : Case ; dative : Case ; genitive : Case ;
To abstract over number names, we define the following.
Number : Type ; singular : Number ; plural : Number ;
mkN : overload {
The regular heuristics recognizes some suffixes, from which it guesses the gender and the declension: e, ung, ion give the feminine with plural ending -n, -en, and the rest are masculines with the plural -e (without Umlaut).
mkN : (Stufe : Str) -> N ;
The 'almost regular' case is much like the information given in an ordinary dictionary. It takes the singular and plural nominative and the gender, and infers the other forms from these.
mkN : (Bild,Bilder : Str) -> Gender -> N ;
Worst case: give all four singular forms, two plural forms (others + dative), and the gender.
mkN : (x1,_,_,_,_,x6 : Str) -> Gender -> N -- mann, mann, manne, mannes, männer, männern };
Relational nouns need a preposition. The most common is von with the dative, and there is a special case for regular nouns.
mkN2 : overload { mkN2 : Str -> N2 ; mkN2 : N -> N2 ; mkN2 : N -> Prep -> N2 } ;
Use the function mkPrep
or see the section on prepositions below to
form other prepositions.
Some prepositions are moreover constructed in StructuralGer.
Three-place relational nouns (die Verbindung von x nach y) need two prepositions.
mkN3 : N -> Prep -> Prep -> N3 ;
Proper names, with an s genitive and other cases like the nominative, are formed from a string. Final s (Johannes-Johannes) is taken into account.
mkPN : overload { mkPN : Str -> PN ;
If only the genitive differs, two strings are needed.
mkPN : (nom,gen : Str) -> PN ;
In the worst case, all four forms are needed.
mkPN : (nom,acc,dat,gen : Str) -> PN } ;
mkA : overload {
The regular adjective formation works for most cases, and includes variations such as teuer - teurer, böse - böser.
mkA : Str -> A ;
In the worst case, adjectives need three forms - one for each degree.
mkA : (gut,besser,beste : Str) -> A -- gut,besser,beste };
Invariable adjective are a special case.
invarA : Str -> A ; -- prima
Two-place adjectives are formed by adding a preposition to an adjective.
mkA2 : A -> Prep -> A2 ;
Adverbs are formed from strings.
mkAdv : Str -> Adv ;
A preposition is formed from a string and a case.
mkPrep : Str -> Case -> Prep ;
Often just a case with the empty string is enough.
accPrep : Prep ; datPrep : Prep ; genPrep : Prep ;
A couple of common prepositions (always with the dative).
von_Prep : Prep ; zu_Prep : Prep ;
mkV : overload {
Regular verbs (weak verbs) need just the infinitive form.
mkV : (führen : Str) -> V ;
Irregular verbs use Ablaut and, in the worst cases, also Umlaut.
mkV : (sehen,sieht,sah,sähe,gesehen : Str) -> V ;
The worst-case constructor needs six forms:
mkV : (geben, gibt, gib, gab, gäbe, gegeben : Str) -> V ;
To add a movable suffix e.g. auf(fassen).
mkV : Str -> V -> V };
To remove the past participle prefix ge, e.g. for the verbs prefixed by be-, ver-.
no_geV : V -> V ;
To change the auxiliary from haben (default) to sein and vice-versa.
seinV : V -> V ; habenV : V -> V ;
Reflexive verbs can take reflexive pronouns of different cases.
reflV : V -> Case -> V ;
mkV2 : overload {
Two-place verbs with a preposition.
mkV2 : V -> Prep -> V2 ;
Two-place verbs with direct object (accusative, transitive verbs).
mkV2 : V -> V2 ;
Two-place verbs with object in the given case.
mkV2 : V -> Case -> V2 };
Three-place (ditransitive) verbs need two prepositions, of which the first one or both can be absent.
mkV3 : V -> Prep -> Prep -> V3 ; -- sprechen, mit, über dirV3 : V -> Prep -> V3 ; -- senden,(accusative),nach accdatV3 : V -> V3 ; -- give,accusative,dative
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 -> 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
.
