acl
: clausal modifier of noun
acl
is used for finite and non-finite clauses that modify a noun, including cases of secondary predication. In Norwegian, relative clauses are assigned a language-specific subtype acl:relcl.
The acl
relation is also used for optional predicatives.
acl:relcl
: relative clause
This language-specific relation is used for relative clauses in Norwegian and the acl:relcl
relation is assigned to the main predicate of the relative clause. Relative clauses modify a nominal element and are often initiated by the relative pronoun som “that” which is assigned a nominal relation to the main predicate of the relative clause.
The relative pronoun may be omitted when it stands in a non-subject relation to the predicate of the relative clause:
Note that due to the analysis of the copula construction (cop), the main predicate of a relative clause may also be an adjective or even a noun:
advcl
: adverbial clause modifier
An adverbial clause modifier is a clause which modifies a verb or other predicate (adjective, etc.), as a modifier not as a core complement. This includes things such as a temporal clause, consequence, conditional clause, purpose clause, etc. The dependent must be clausal (or else it is an advmod) and the dependent is the main predicate of the clause.
advmod
: adverbial modifier
An adverbial modifier of a word is a (non-clausal) adverb or adverbial phrase that serves to modify the meaning of the word.
amod
: adjectival modifier
An adjectival modifier of a noun is any adjectival phrase that serves to modify the meaning of the noun. In Norwegian, adjectival modifiers are placed before the noun they modify.
appos
: appositional modifier
An appositional modifier of a noun is a nominal immediately following the first noun that serves to define or modify that noun.
In Norwegian, it is used also for titles which usually precede their head.
aux
: auxiliary
An auxiliary of a clause is a non-main verb of the clause, e.g., a modal auxiliary, or a form of ha “have” or være “be” in a periphrastic tense. Exception: Auxiliary verb used to construct the passive voice is not labeled aux but auxpass.
auxpass
: passive auxiliary
A passive auxiliary of a clause is a non-main verb of the clause which contains the passive information.
case
: case marking
The case relation is used for any case-marking element which is treated as a separate syntactic word, in Norwegian it is used to mark the relation between a preposition and what is traditionally known as its complement (its head in the UD scheme).
cc
: coordinating conjunction
For more on coordination, see the conj relation. A cc is the relation between the first conjunct and the coordinating conjunction delimiting another conjunct.
A coordinating conjunction may also appear at the beginning of a sentence. This is also called a cc, and it depends on the root predicate of the sentence.
ccomp
: clausal complement
A clausal complement of a verb or adjective is a dependent clause which is a core argument. That is, it functions like an object of the verb, or adjective.
Such clausal complements may be finite or nonfinite. However, if the subject of the clausal complement is controlled the appropriate relation is xcomp.
compound
: compound
For Norwegian the compound
relation is used only for verbal particle constructions with the language-specific subtype compound:prt.
compound:prt
: compound:prt
This language-specific relation is used for verbal particles in Norwegian and describes the relation of the particle to its verbal head.
Particles exhibit a number of syntactic properties which sets them apart from regular prepositions. For instance, a pronominal object may intercede the verb and the preposition in the particle case satte den på “put it on”, but not in the case of a regular preposition and its complement *lette den etter “*looked it for”, and only complements of a preposition may occur in an impersonal passive Det ble lett etter den nye boka “It was looked for the new book”, but an object in a particle construction may not *Det ble satt den på “*It was put it on”.

conj
: conjunct
A conjunct is the relation between two elements connected by a coordinating conjunction, such as og “and”, eller “or”, etc. We treat conjunctions asymmetrically: The head of the relation is the first conjunct and all the other conjuncts depend on it via the conj
relation.
cop
: copula
A copula is the relation between the complement of a copular verb and the copular verb være “to be”. The copula is treated as a dependent of the lexical verb.
This analysis entails that in copula clauses, the main predicate is not verbal, but rather an adjectival or even nominal (as in the above example).
Note that there are occurrences of være “to be” which do not give rise to a copula analysis, such as in cleft constructions (see expl).
csubj
: clausal subject
A clausal subject is a clausal syntactic subject of a clause, i.e., the subject is itself a clause.
When the matrix clause is a copula construction, the head of the csubj
may be an adjectival (or even nominal) predicate.
csubjpass
: clausal passive subject
A clausal passive subject is a clausal syntactic subject of a passive clause. In the example below, the clause At de mener alvor “That they are serious” is the csubjpass
of the passive verb illustreres “illustrated-PASS”.
dep
: unspecified dependency
A dependency is labeled as dep when a system is unable to determine a more precise dependency relation between two words. This relation is not used for Norwegian.
det
: determiner
The relation determiner (det
) holds between a nominal head and its determiner. Most commonly, a word of POS DET will have the relation det
and vice versa.
Other parts of speech than DET
may in some cases be assigned a determiner relation to a nominal head.
For Norwegian the det
relation is also used for genitive nouns, like årets “this year’s” and quantity nouns like rekke “number-of”.
discourse
: discourse element
This is used for interjections and other discourse particles and elements, which are not clearly linked to the structure of the sentence except in an expressive way.
dislocated
: dislocated elements
This relation is not used for Norwegian.
dobj
: direct object
A direct object is a nominal which is the (accusative) object of the verbal predicate.
expl
: expletive
This relation captures expletive nominals. These are nominals that appear in an argument position of a predicate but which do not themselves satisfy any of the semantic roles of the predicate. The main predicate of the clause (the verb or predicate adjective or noun) is the governor.
For Norwegian, the expletive element is expressed using the neuter pronoun det “it” and the expl
relation is used for both expletive subjects and objects.
Presentational construction
In Norwegian expletives occur in the presentational construction, which involves an expletive subject, an active verb and an indefinite subject (en debatt “a debate” in the example below).
Impersonal passive
Norwegian employs the impersonal passive construction, where there is an expletive subject and the underlying subject is unexpressed.
Clause-anticipating constructions
These constructions contain a finite or non-finite clause which semantically may be regarded as the subject, but where the subject position is occupied by an expletive.
We also find clause-anticipating constructions with expletive objects.
Clefts
Clefts are quite common in Norwegian. They contain an expletive subject, a form of være “to be” and a relative clause. Note that in clefts we do not adopt a copula analysis of the verb være “er”.

foreign
: foreign words
We use foreign
to label sequences of foreign words.
goeswith
: goes with
This relation links two parts of a word that are separated in text that is not well edited. It is used in Norwegian for elements that constitute syntactic errors and that otherwise are difficult to assign a relation in the analysis.
iobj
: indirect object
The indirect object of a verb is any nominal phrase that is a core argument of the verb but is not its subject or direct object. The iobj
relation presupposes a dobj
argument of the same word and is only used for nominal arguments. Note that nominals with a preposition such as til “to” which are semantically similar to indirect object in the expression of a recipient role are not analyzed as iobj
.
list
: list
The list
relation is not used for Norwegian.
mark
: marker
A marker is the word introducing a subordinate clause and the marker is a dependent of the subordinate clause head. In Norwegian it is used for both finite and non-finite subordinate clauses.
mwe
: multi-word expression
The mwe
relation is not used for Norwegian.
name
: name
The name
relation is used for proper nouns constituted of multiple nominal elements.
Names are annotated in a flat, head-initial structure, in which all words in the name modify the first one using the name label.
A flat analysis is also adopted for names where there is a clear syntactic analysis (unlike the UD guidelines) due to the automated conversion procedure.
neg
: negation modifier
The negation modifier is the relation between a negation word and the word it modifies. For Norwegian, it is employed for the negative determiner ingen “no” and the negative adverb ikke “not”.
nmod
: nominal modifier
The nmod relation is used for nominal modifiers. They depend either on another noun (group “noun dependents”) or on a predicate (group “non-core dependents of clausal predicates”).
nmod
is a noun (or noun phrase) functioning as a non-core (oblique) argument or adjunct. This means that it functionally corresponds to an adverbial when it attaches to a verb, adjective or other adverb. But when attaching to a noun, it corresponds to an attribute.
nmod
is used for nouns modified by a preposition.
The nmod
relation is also used for temporal modifiers expressed as nominals:
nsubj
: nominal subject
A nominal subject is a nominal phrase which is the subject of a clause. The governor of the nsubj
relation might not always be a verb: when the verb is a copular verb, the root of the clause is the complement of the copular verb, which can be an adjective or noun.
Note that in cases where there is an expletive subject (expl), the nsubj
relation is used to express the potential/postposed subject:
nsubjpass
: passive nominal subject
A passive nominal subject is a noun phrase which is the syntactic subject of a passive clause. In Norwegian, the passive subject is the dependent of a verb with passive marking or a participle with a passive auxiliary attached.
nummod
: numeric modifier
A numeric modifier of a noun is any number phrase that serves to modify the meaning of the noun with a quantity.
parataxis
: parataxis
The parataxis relation is a relation between a word (often the main predicate of a sentence) and other elements, such as a sentential parenthetical or a clause after a “:” or a “;”, placed side by side without any explicit coordination, subordination, or argument relation with the head word.
The Norwegian parataxis
relation is largely used for reported speech and some other parentheticals.
punct
: punctuation
Tokens with the relation punct always attach to content words (except in cases of ellipsis) and can never have dependents. Since punct is not a normal dependency relation, the usual criteria for determining the head word do not apply. Instead, we use the following principles:
- A punctuation mark separating coordinated units is attached to the first conjunct.
- A punctuation mark preceding or following a subordinated unit is attached to this unit.
- Within the relevant unit, a punctuation mark is attached at the highest possible node that preserves projectivity.
- Paired punctuation marks (quotes and brackets) should be attached to the same word unless that would create non-projectivity. This word is usually the head of the phrase enclosed in the paired punctuation.
remnant
: remnant in ellipsis
The remnant
relation is used to provide a satisfactory treatment of ellipsis. In Norwegian, the remnant element is attached to the main predicate of the clause (and not to the correlate in the preceding context).
reparandum
: overridden disfluency
This relation is not used for Norwegian.
root
: root
The root grammatical relation points to the root of the sentence.
vocative
: vocative
This relation is not used in Norwegian.
xcomp
: open clausal complement
An open clausal complement (xcomp) of a verb or an adjective is a predicative or clausal complement without its own subject. The reference of the subject is necessarily determined by an argument external to the xcomp. This is often referred to as obligatory control.
In Norwegian xcomp
is used for infinitival clauses
This relation is also used for cases of obligatory secondary predication
xcomp
is also used for copula-like verbs such as bli
“become”, kalle “call”, hete “named” in Norwegian.
