Nominals
This section of the syntax overview is devoted to nominals. The UD annotation assumes the nominal, or noun phrase, as one of the basic structures that we expect to find in all languages. A nominal minimally consists of a noun, proper noun or pronoun.
Modifier Dependents
A nominal head does not take any core arguments but may be associated with different types of modifiers:
- An
nmod
is a nominal phrase modifying the head of another nominal phrase, with or without a special case marker. Treebanks may optionally usenmod:poss
to distinguish non-adpositional possessives. - An
appos
is a nominal phrase that follows the head of another nominal phrase and stands in a co-reference or other equivalence relation to it. - An
amod
is an adjective modifying the head of a nominal phrase. - A
nummod
is a numeral modifying the head of a nominal phrase. - An
acl
is a clause modifying the head of a nominal phrase, with the relative clauseacl:relcl
as an important subtype.
Function Word Dependents
Nominals may also contain the following typical function word dependents:
- Determiners attach to the head of the nominal with the
det
relation. - Adpositions attach to the head of the nominal with the
case
relation. - Classifiers attach to a numeral or possessive with the
clf
relation.
