Continuing the discussion from Spell check doesn’t work:
It is disconcerting that spell check (as you type) doesn’t work unless you use English (USA) in all language settings. (<Options…> [check out 3 entry points])
The same situation occurs in Open Office.
The US lanuage invariably will drop “u” from words like “colour”. These “quirks” can be added to your custom dictionary, The spell check wil pick these up in the future.
It is a program error (and possibly very early in the development of the suites). It applies to Calc as well as Write.
The program should “remember” your new settings.
Could you give more technical details? At least OS name, LO version and save format.
I write documents in several languages and, among these, I prefer English (UK) over English (USA) and have no problem.
When I create multi-lingual documents, spelling is correctly checked in the “local context”. Perhaps, attach a “faulty” 1- or 2-page document so that we can have a look at it.
Sorry, I should have included:-
Operating system – Windows 11,
LibreOffice Version no, – 25.8.2.2
Most documents are saved in LibreOffice and Open Office defaault/native format (but spell checking is done usually long before saving).
My preference for a language base was English (AUS) and it was while using this base the spell check issue was apparent (a good tester would try all language bases - but I was content to find a solution and escalated no further).
I am not familiar with W$ installation procedure. Under Linux, LO comes with no language except en_US. Others languages require installing a specific “package”. English variants are provided by libreoffice-langpack-en. Spellchecking is under responsibility of hunspell assisted by packages hunspell-en, hunspell-en-US and hunspell-en-GB.
If you found a solution, please share it for others’ benefit.
If you live in Australia and you bought your computer there, then probably the operating system is set to USA (a bizarre and hugely irritating inconvenience by the importers) which is why everything else defaults to USA including your LibreOffice download.
