<h1> Noun: Nouns, noun phrases, and determiners</h1>
<pre>
abstract Noun = Cat ** {
</pre>
<h2> Noun phrases</h2>
The three main types of noun phrases are
- common nouns with determiners
- proper names
- pronouns
<p>
<p>
<pre>
fun
DetCN : Det -> CN -> NP ; -- the man
UsePN : PN -> NP ; -- John
UsePron : Pron -> NP ; -- he
</pre>
Pronouns are defined in the module [``Structural`` Structural.html].
A noun phrase already formed can be modified by a <tt>Predet</tt>erminer.
<pre>
PredetNP : Predet -> NP -> NP; -- only the man
</pre>
A noun phrase can also be postmodified by the past participle of a
verb, by an adverb, or by a relative clause
<pre>
PPartNP : NP -> V2 -> NP ; -- the man seen
AdvNP : NP -> Adv -> NP ; -- Paris today
RelNP : NP -> RS -> NP ; -- Paris, which is here
</pre>
Determiners can form noun phrases directly.
<pre>
DetNP : Det -> NP ; -- these five
</pre>
<h2> Determiners</h2>
The determiner has a fine-grained structure, in which a 'nucleus'
quantifier and an optional numeral can be discerned.
<pre>
DetQuant : Quant -> Num -> Det ; -- these five
DetQuantOrd : Quant -> Num -> Ord -> Det ; -- these five best
</pre>
Whether the resulting determiner is singular or plural depends on the
cardinal.
All parts of the determiner can be empty, except <tt>Quant</tt>, which is
the <i>kernel</i> of a determiner. It is, however, the <tt>Num</tt> that determines
the inherent number.
<pre>
NumSg : Num ;
NumPl : Num ;
NumCard : Card -> Num ;
</pre>
<tt>Card</tt> consists of either digits or numeral words.
<pre>
data
NumDigits : Digits -> Card ; -- 51
NumNumeral : Numeral -> Card ; -- fifty-one
</pre>
The construction of numerals is defined in [Numeral Numeral.html].
A <tt>Card</tt> can be modified by certain adverbs.
<pre>
fun
AdNum : AdN -> Card -> Card ; -- almost 51
</pre>
An <tt>Ord</tt> consists of either digits or numeral words.
Also superlative forms of adjectives behave syntactically like ordinals.
<pre>
OrdDigits : Digits -> Ord ; -- 51st
OrdNumeral : Numeral -> Ord ; -- fifty-first
OrdSuperl : A -> Ord ; -- warmest
</pre>
Definite and indefinite noun phrases are sometimes realized as
neatly distinct words (Spanish <i>un, unos ; el, los</i>) but also without
any particular word (Finnish; Swedish definites).
<pre>
IndefArt : Quant ;
DefArt : Quant ;
</pre>
Nouns can be used without an article as mass nouns. The resource does
not distinguish mass nouns from other common nouns, which can result
in semantically odd expressions.
<pre>
MassNP : CN -> NP ; -- (beer)
</pre>
Pronouns have possessive forms. Genitives of other kinds
of noun phrases are not given here, since they are not possible
in e.g. Romance languages. They can be found in <tt>Extra</tt> modules.
<pre>
PossPron : Pron -> Quant ; -- my (house)
</pre>
Other determiners are defined in [Structural Structural.html].
<h2> Common nouns</h2>
Simple nouns can be used as nouns outright.
<pre>
UseN : N -> CN ; -- house
</pre>
Relational nouns take one or two arguments.
<pre>
ComplN2 : N2 -> NP -> CN ; -- mother of the king
ComplN3 : N3 -> NP -> N2 ; -- distance from this city (to Paris)
</pre>
Relational nouns can also be used without their arguments.
The semantics is typically derivative of the relational meaning.
<pre>
UseN2 : N2 -> CN ; -- mother
Use2N3 : N3 -> N2 ; -- distance (from this city)
Use3N3 : N3 -> N2 ; -- distance (to Paris)
</pre>
Nouns can be modified by adjectives, relative clauses, and adverbs
(the last rule will give rise to many 'PP attachment' ambiguities
when used in connection with verb phrases).
<pre>
AdjCN : AP -> CN -> CN ; -- big house
RelCN : CN -> RS -> CN ; -- house that John bought
AdvCN : CN -> Adv -> CN ; -- house on the hill
</pre>
Nouns can also be modified by embedded sentences and questions.
For some nouns this makes little sense, but we leave this for applications
to decide. Sentential complements are defined in [Verb Verb.html].
<pre>
SentCN : CN -> SC -> CN ; -- question where she sleeps
</pre>
<h2> Apposition</h2>
This is certainly overgenerating.
<pre>
ApposCN : CN -> NP -> CN ; -- city Paris (, numbers x and y)
}
</pre>
