UD for Swedish 
Tokenization and Word Segmentation
- Words are generally delimited by whitespace or punctuation. Exceptions:
- Numerical expressions (including dates) are treated as single words and may contain punctuation or whitespace: 1.1.1970, 11:00, 2 000.
- Abbreviations are treated as single words and may contain punctuation or whitespace: t.ex., bl a.
- Multiword tokens are not used in Swedish.
Morphology
Tags
- Swedish uses all 17 universal tags.
- The only words tagged PART are the infinitive marker att and the negation particles inte, icke, ej.
- Auxiliaries (AUX) are all verbal in Swedish and can be grouped into four types:
- The copula vara (be).
- The temporal auxiliary ha (have), which combines with the supine form of the main verb to form perfect tenses.
- The passive auxiliary bli (get), which combines with the past participle of the main verb to form passives.
- Modal and aspectual verbs that combine with the bare infinitive of the main verb, such as måste (must) and kunde (could).
- The tag DET is used for articles and pronominal words used with a determiner function, including possessives. The tag PRON is reserved for pronouns occurring as the head of a noun phrase.
- Participles (both present and past) are mainly used adjectivally in Swedish and are generally tagged ADJ. The only exception is that past participles used to form periphrastic passives are tagged VERB.
For more information, see the list of Swedish POS tags.
Features
- Nouns have inherent Gender and inflect for Number (singular or plural), Definite (indefinite or definite) and Case (nominative or genitive).
- Verbs inflect for Voice (active or passive). Finite forms in indicative mood in addition inflect for Tense (present or paste). There are three types of nonfinite forms: infinitives, participles (present and past), and supine (used to form perfect tenses together with the auxiliary have).
- Adjectives agree with nouns (in both attributive and predicate position) with respect to the features Gender, Number and Definite. In addition, many adjectives inflect for Degree (positive, comparative, superlative) and for Case when used to head noun phrases.
- Adverbs inflect only for Degree.
- Personal pronouns inflect for Case with three values (nominative, accusative, genitive).
- Determiners agree with nouns in the same way as adjectives.

Syntax
- Subjects have the following characteristics:
- Word order: Subjects immediately follow the finite verb and precede negation in verb-initial main clauses.
- Case marking: Subjects occur in nominative case without adpositions.
- Passivization: Subjects are suppressed when verbs (both intransitive and transitive) are passivized.
- Control: Subjects control the subjects of absolute adverbials.
- Relativization: Relative pronouns with subject function cannot be omitted.
- Objects have the following characteristics:
- Word order: Objects immediately follow the main verb unless topicalized.
- Case marking: Objects occur in nominative case (if nouns) or accusative case (if pronouns) without adpositions.
- Passivization: Objects become (non-expletive) subjects when verbs are passivized.
- The copula verb vara (be) is used in equational, attributional, locative, possessive and benefactory nonverbal clauses. Existential clauses normally use a different verb (finnas).
- The following subtypes are used in Swedish:
- acl:relcl for relative clauses
- aux:pass for passive auxiliaries
- compound:prt for verb particles
- csubj:pass for clausal subjects of passive verbs
- flat:name for exocentric complex names
- nmod:poss for possessive/genitive modifiers
- nsubj:pass for nominal subjects of passive verbs
- obl:agent for agents of passive verbs
