I am using TeXnicCenter for writing LaTeX documents. Unfortunately, when I am writing in Finnish as I usually do, there is no spell checker in Finnish in TeXnicCenter. All the lines are underlined in red, and this is not nice. I know that there is Voikko for Finnish spell checking in LibreOffice, but is it possible to apply Voikko for TeXnicCenter? TeXnicCenter is using Hunspell; I downloaded the voikko-laaja.oxt file but I could not find in this package any files with .aff and .dic suffices.

  • Have you found a finnish dictionary (.dic and .aff) for tex editors? – remus Mar 31 '15 at 11:14

    People, this question is not a duplicate! Unfortunately there are no .dic and .aff for Finnish because the format is not compatible with the language. I think switching to another editor would be the solution - an editor that relies on a different spell checking system. – remus Apr 1 '15 at 18:39
  • There is spell-fi.sourceforge.net for Finnish to get .dic and .aff files and like you said Voikko voikko.puimula.org – Oni Jul 5 '19 at 15:48

The file type .oxt is an archive. So:

  1. Open the file <filename>.oxt using 7-Zip;
  2. Locate the appropriate .dic and .aff files inside the archive. Typically they are called <lang>_<dialect>.dic and <lang>_<dialect>.aff;
  3. Copy these files to

    C:\Program Files\TeXnicCenter\Dictionaries

    Note that the naming convention is strict. So, if your files have the format <lang>-<dialect>, rename them to <lang>_<dialect>.

  4. (Re)start TeXnicCenter;
  5. Identify the new language/dialect from the Tools > Options... > Spelling menu:

    I downvoted your answer because, as the question text says, there is no .dic nor .aff file in the .oxt archive for Finnish. – remus Mar 31 '15 at 11:10
