I need to use Indian Language 'Marathi' to prepare a presentation. But there is no Marathi or Hindi to set as document language. Probably therefore even when I try to change the properties (e.g., font size) of the Marathi text I enter, things happen like the font won't get bigger even if I try to change it. How can I deal with it?
Tools -> Options -> Language Settings -> Languages. There is a check box labeled
Complex text layout (CTL). Ensure that this box is checked.
Then find Hindi and Marathi in the list to the right of the check box.
On my Ubuntu machine with LibreOffice 18.104.22.168, Hindi is set as the default CTL language. English (USA) is the default Western language.
In LibreOffice 4, the options screen has the check box in a different place. See https://ask.libreoffice.org/en/question/24374/libreoffice-4-does-not-let-me-select-ctl-language/ for screen shots.
