--2 Parameters
--
-- To abstract over gender names, we define the following identifiers.
</P>
<P>
oper
Gender : Type ;
</P>
<P>
human : Gender ;
nonhuman : Gender ;
masculine : Gender ;
feminite : Gender ;
</P>
<P>
-- To abstract over number names, we define the following.
</P>
<P>
Number : Type ;
</P>
<P>
singular : Number ;
plural : Number ;
</P>
<P>
-- To abstract over case names, we define the following.
</P>
<P>
Case : Type ;
</P>
<P>
nominative : Case ;
genitive : Case ;
</P>
<P>
-- Prepositions are used in many-argument functions for rection.
</P>
<P>
Preposition : Type ;
</P>
<P>
--2 Nouns
</P>
<P>
-- Worst case: give all four forms and the semantic gender.
</P>
<P>
mkN : (man,men,man's,men's : Str) -&gt; N ;
</P>
<P>
-- The regular function captures the variants for nouns ending with
-- <I>s</I>,<I>sh</I>,<I>x</I>,<I>z</I> or <I>y</I>: <I>kiss - kisses</I>, <I>flash - flashes</I>;
-- <I>fly - flies</I> (but <I>toy - toys</I>),
</P>
<P>
regN : Str -&gt; N ;
</P>
<P>
-- In practice the worst case is just: give singular and plural nominative.
</P>
<P>
mk2N : (man,men : Str) -&gt; N ;
</P>
<P>
-- All nouns created by the previous functions are marked as
-- <CODE>nonhuman</CODE>. If you want a <CODE>human</CODE> noun, wrap it with the following
-- function:
</P>
<P>
genderN : Gender -&gt; N -&gt; N ;
</P>
<P>
--3 Compound nouns
--
-- All the functions above work quite as well to form compound nouns,
-- such as <I>baby boom</I>.
</P>
<P>
--3 Relational nouns
--
-- Relational nouns (<I>daughter of x</I>) need a preposition.
</P>
<P>
mkN2 : N -&gt; Preposition -&gt; N2 ;
</P>
<P>
-- The most common preposition is <I>of</I>, and the following is a

<P>
-- Use the function <CODE>mkPreposition</CODE> or see the section on prepositions below to

</P>
<P>
mkN3 : N -&gt; Preposition -&gt; Preposition -&gt; N3 ;
</P>
<P>
--3 Relational common noun phrases
--
-- In some cases, you may want to make a complex <CODE>CN</CODE> into a
-- relational noun (e.g. <I>the old town hall of</I>).
</P>
<P>
cnN2 : CN -&gt; Preposition -&gt; N2 ;
cnN3 : CN -&gt; Preposition -&gt; Preposition -&gt; N3 ;
</P>
<P>
--
--3 Proper names and noun phrases
--
-- Proper names, with a regular genitive, are formed as follows
</P>
<P>
regPN : Str -&gt; Gender -&gt; PN ; -- John, John's
</P>
<P>
-- Sometimes you can reuse a common noun as a proper name, e.g. <I>Bank</I>.
</P>
<P>
nounPN : N -&gt; PN ;
</P>
<P>
-- To form a noun phrase that can also be plural and have an irregular
-- genitive, you can use the worst-case function.
</P>
<P>
mkNP : Str -&gt; Str -&gt; Number -&gt; Gender -&gt; NP ;
</P>
<P>
--2 Adjectives
</P>
<P>
-- Non-comparison one-place adjectives need two forms: one for
-- the adjectival and one for the adverbial form (<I>free - freely</I>)
</P>
<P>
mkA : (free,freely : Str) -&gt; A ;
</P>
<P>
-- For regular adjectives, the adverbial form is derived. This holds
-- even for cases with the variation <I>happy - happily</I>.
</P>
<P>
regA : Str -&gt; A ;
</P>
<P>
--3 Two-place adjectives
--
-- Two-place adjectives need a preposition for their second argument.
</P>
<P>
mkA2 : A -&gt; Preposition -&gt; A2 ;
</P>
<P>
-- Comparison adjectives may two more forms.
</P>
<P>
ADeg : Type ;
</P>
<P>
mkADeg : (good,better,best,well : Str) -&gt; ADeg ;
</P>
<P>
-- The regular pattern recognizes two common variations:
-- <I>-e</I> (<I>rude</I> - <I>ruder</I> - <I>rudest</I>) and
-- <I>-y</I> (<I>happy - happier - happiest - happily</I>)
</P>
<P>
regADeg : Str -&gt; ADeg ; -- long, longer, longest
</P>
<P>
-- However, the duplication of the final consonant is nor predicted,
-- but a separate pattern is used:
</P>
<P>
duplADeg : Str -&gt; ADeg ; -- fat, fatter, fattest
</P>
<P>
-- If comparison is formed by <I>more, //most</I>, as in general for//
-- long adjective, the following pattern is used:
</P>
<P>
compoundADeg : A -&gt; ADeg ; -- -/more/most ridiculous
</P>
<P>
-- From a given <CODE>ADeg</CODE>, it is possible to get back to <CODE>A</CODE>.
</P>
<P>
adegA : ADeg -&gt; A ;
</P>
<P>
--2 Adverbs
</P>
<P>
-- Adverbs are not inflected. Most lexical ones have position
-- after the verb. Some can be preverbal (e.g. <I>always</I>).
</P>
<P>
mkAdv : Str -&gt; Adv ;
mkAdV : Str -&gt; AdV ;
</P>
<P>
-- Adverbs modifying adjectives and sentences can also be formed.
</P>
<P>
mkAdA : Str -&gt; AdA ;
</P>
<P>
--2 Prepositions
--
-- A preposition as used for rection in the lexicon, as well as to
-- build <CODE>PP</CODE>s in the resource API, just requires a string.
</P>
<P>
mkPreposition : Str -&gt; Preposition ;
mkPrep : Str -&gt; Prep ;
</P>
<P>
-- (These two functions are synonyms.)
</P>
<P>
--2 Verbs
--
-- Except for <I>be</I>, the worst case needs five forms: the infinitive and
-- the third person singular present, the past indicative, and the
-- past and present participles.
</P>
<P>
mkV : (go, goes, went, gone, going : Str) -&gt; V ;
</P>
<P>
-- The regular verb function recognizes the special cases where the last
-- character is <I>y</I> (<I>cry - cries</I> but <I>buy - buys</I>) or <I>s</I>, <I>sh</I>, <I>x</I>, <I>z</I>
-- (<I>fix - fixes</I>, etc).
</P>
<P>
regV : Str -&gt; V ;
</P>
<P>
-- The following variant duplicates the last letter in the forms like
-- <I>rip - ripped - ripping</I>.
</P>
<P>
regDuplV : Str -&gt; V ;
</P>
<P>
-- There is an extensive list of irregular verbs in the module <CODE>IrregularGer</CODE>.
-- In practice, it is enough to give three forms,
-- e.g. <I>drink - drank - drunk</I>, with a variant indicating consonant
-- duplication in the present participle.
</P>
<P>
irregV : (drink, drank, drunk : Str) -&gt; V ;
irregDuplV : (get, got, gotten : Str) -&gt; V ;
</P>
<P>
--3 Verbs with a particle.
--
-- The particle, such as in <I>switch on</I>, is given as a string.
</P>
<P>
partV : V -&gt; Str -&gt; V ;
</P>
<P>
--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 <CODE>V</CODE>.
</P>
<P>
mkV2 : V -&gt; Preposition -&gt; V2 ;
</P>
<P>
dirV2 : V -&gt; V2 ;
</P>
<P>
--3 Three-place verbs
--
-- Three-place (ditransitive) verbs need two prepositions, of which
-- the first one or both can be absent.
</P>
<P>
mkV3 : V -&gt; Preposition -&gt; Preposition -&gt; V3 ; -- speak, with, about
dirV3 : V -&gt; Preposition -&gt; V3 ; -- give,_,to
dirdirV3 : V -&gt; V3 ; -- give,_,_
</P>
<P>
--3 Other complement patterns
--
-- Verbs and adjectives can take complements such as sentences,
-- questions, verb phrases, and adjectives.
</P>

<P>
This is an API to the user of the resource grammar
for adding lexical items. It gives functions for forming
expressions of open categories: nouns, adjectives, verbs.
</P>
<P>
Closed categories (determiners, pronouns, conjunctions) are
accessed through the resource syntax API, <CODE>Structural.gf</CODE>.
</P>
<P>
The main difference with <CODE>MorphoGer.gf</CODE> 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.
</P>
<P>
The structure of functions for each word class <CODE>C</CODE> is the following:
first we give a handful of patterns that aim to cover all
regular cases. Then we give a worst-case function <CODE>mkC</CODE>, which serves as an
escape to construct the most irregular words of type <CODE>C</CODE>.
However, this function should only seldom be needed: we have a

The regular heuristics recognizes some suffixes, from which it
guesses the gender and the declension: <I>e, ung, ion</I> give the
feminine with plural ending <I>-n, -en</I>, and the rest are masculines
with the plural <I>-e</I> (without Umlaut).

The 'almost regular' case is much like the information given in an ordinary

gender, and infers the other forms from these.
