Pronouns are defined in the module <A HREF="Structural.html"><CODE>Structural</CODE></A>.

A noun phrase already formed can be modified by a <CODE>Predet</CODE>erminer.

verb or by an adverb.

<P>

The determiner has a fine-grained structure, in which a 'nucleus'
|
|
quantifier and two optional parts can be discerned.
|
|
The cardinal numeral is only available for plural determiners.
|
|
(This is modified from CLE by further dividing their <CODE>Num</CODE> into
|
|
cardinal and ordinal.)

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
|
|
<A HREF="../abstract/Extra.gf"><CODE>Extra</CODE></A>.

Definite and indefinite constructions are sometimes realized as
|
|
neatly distinct words (Spanish <I>un, unos ; el, los</I>) but also without
|
|
any particular word (Finnish; Swedish definites).

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.

Relational nouns take one or two arguments.

Relational nouns can also be used without their arguments.
|
|
The semantics is typically derivative of the relational meaning.

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 owns

AdvCN : CN -> Adv -> CN ; -- house on the hill

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 <A HREF="Verb.html">Verb</A>.
