    No. The grammar checker does NOT work. Period.

      Agree. The spell checker does work, but the grammar checker does not.
      I use the British English language because I study in the UK, so I need to hand in all work in BE. For British English, the grammar checker does not work.
      For example if you repeat a word “The the dog …” libre office doesn’t notice it.
      If you use American English instead of British English “utilize” vs “utilise”, libre office doesn’t notice it.
      This is really problematic for me.
