I have libreoffice and mythes installed in my system yet I don't see thesaurus in libreoffice. Is there some other package I need to installed or am I missing something.
By the way, I just installed Solus Budgie. First time. A nice experience so far.

P.S. In Libreoffice writer Tools show Thesaurus as greyed out and in Tools > options > Language settings > Writing aids shows hunspell and libhyphen only. No Thesaurus.

Working fine here... make sure you have installed the dictionary you need

What dictionary? Can you elaborate please? I need thesaurus for English.

    subluminal The hunspell dictionary for the language you want. You should also check the document is set in the same language. LO can be very touchy with this.

    I have hunspell-en installed. Document is blank. New libreoffice-writer document.

    Installing libreoffice-common-dictionaries package fixed it. Thanks.
