We would like to facilitate anyone who is interested in the Frisian language with a variety of language services. One of our larger projects is, an important digital tool for writing Frisian since 2021 and the successor to With a team of lexicographers, the Fryske Akademy has also worked on the preferred word list and the official spelling rules (in force from 2015), which have also been integrated into The Taalportaal and websites have been developed for researchers and programmers.

Foarkarswurdlist and official spelling

Is it Italië or Itaaljetelefoan or tillefoan? The Foarkarswurdlist (Preferred Word List) foar it Frysk, which the Fryske Akademy has drawn up, provides clarity about the preferred forms in Frisian spelling. The Foarkarswurdlist is not a mandatory language standard, but can be used as a guideline for clear preferred forms in the written Frisian language, for example in official communication and in education. The words from the Foarkarswurdlist have been integrated into the search function of


Official spelling

Frisian has had more or less official spelling rules since 1879, but these have since been changed several times. As a result, over time, the rules and writing practice no longer corresponded completely. For the preparation of the Foarkarswurdlist, the Fryske Akademy has completely re-described the current regulation of the Frisian spelling. This has resulted in the spelling rules and the way in which words are spelled in practice are similar again from now on. These rules regarding the official spelling of Frisian have been in effect since 30 January, 2015 and can be found in the manual  Paadwizer Fryske stavering. Due to a number of rule changes in the Frisian spelling, a limited number of words are written differently (e.g. telefyzje instead of televyzje and útnûging instead of útnoeging). 

In 2020, the Fryske Akademy published a Koroanawurdlist, a supplement with frequent words related to the corona outbreak.


Taalportaal &

Taalportaal is an English-language digital reference work where all grammatical knowledge of Dutch, Frisian and Afrikaans has been brought together by researchers from Fryslân, the Netherlands and South Africa. Taalportaal is a large project that strives for a more comprehensive and authoritative scientific grammar, originally only for Dutch and Frisian. Since 2015, Afrikaans has also been added to the project. Taalportaal (Language Portal) is an interactive knowledge base about these three languages, covering syntax, morphology and phonology. The project is a collaboration of the Meertens InstituteLeiden University, the Institute for Dutch Lexicology, the Fryske Akademy, and the Virtual Institute Vir Afrikaans. The Dutch/Frisian part is funded by NWO , the Netherlands Organisation for Scientific Research; the Afrikaans part is financed by the Suid-Afrikaans Akademie vir Wetenskap en KunsAfrikaans Language and Culture AssociationNoordwest-Universiteit and Dagbreek Trust. is a website for researchers and programmers. It contains a wide variety of (Old) Frisian language resources, such as dictionaries, data, tools and services. Datasets, data models and APIs can be downloaded, Json services are freely available. The underlying data is always maintained.
