UD for Galician 
Galician is an Indo-European language and a part of the Western Ibero-Romance group evolved from Vulgar Latin. It derives from medieval Galician-Portuguese.
Modern Galician is spoken in the Spanish Autonomous Region of Galicia (and in some border regions) by about 2.5 million people, and it is the official language together with Spanish.
Due to its common origin and present similarity, some linguists still consider Galician as a variety of (Galician-)Portuguese. However, it is important to note that the current orthography of Galician is based on the Spanish one (thus being different from the Portuguese spelling).
Tokenization and Word Segmentation
- Words are generally delimited by whitespace or punctuation. Exceptions:
- Few numerical expressions (e.g., telephone numbers) are treated as single words and may contain punctuation or whitespace: 687 614 874.
- URLs, email addresses and other related expressions are treated as single words and may contain punctuation: manuelmaria@as-pg.com.
- Abbreviations are also treated as single words and may contain punctuation: etc..
- Galician has two main types of multiword tokens:
- Verb forms with enclitic pronouns are written together: cómeos=come+os, dixérono=dixeron+o.
- Contractions of prepositions and determiners or pronouns: e.g., ao=a+o, polo=por+o, co=con+o, daquel=de+aquel, nese=en+ese. Other (less frequent) contractions include demonstratives and pronouns: e.g., aqueloutros=aquel+outros.
- Note that some of the above mentioned contracted forms may be ambiguous with single tokens (e.g., dese can be a form of the verb dar of a contraction of de+ese).
Morphology
Tags
- Galician uses all 17 universal tags. However, note that PART is only used in the Galician treebank.
- Auxiliar verbs (AUX) are tagged when they behave as copula (e.g., ser and estar) as well as in verbal periphrases and other constructions where they depend on the main verb (e.g., “poderían chegar”).
- 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.
