How to prevent flagging of repeated dashes as misspelled words in Writer?

When writing tablature for guitar, it’s common to use repeating dashes to represent strings. Is there a way to stop Writer from flagging these as misspelled, yet still leave AutoCorrect on?

I’ve tried:

  • Selecting “Ignore all”, which works, but the flags reappear the next time the document is opened. There is no option presented to add them to my dictionary.

  • Adding one through ten repeating dashes to the AutoCorrect options “Exceptions” tab, even though for some reason only two or three repeats are being flagged.

It’s probably something dumb I’m overlooking, but any suggestions would be much appreciated!

Unless you changed the default colours, the wavy underline is blue not red, denoting a grammar warning, not a misspelling mistake.

AFAIK, Writer does not offer any out-of-the-factory grammar checker. This is likely provided by an extension.

Disabling grammar check either through deactivating the extension or unchecking Check grammar as you type in Tools>Options, Language Settings>Writing Aids should fix the problem.

I never noticed that color change, thanks much for pointing it out.

But, I don’t remember installing any extensions. I’d attach a screenshot of my Extension Manager, but there’s no option to upload an image in comments here.

As far as the dashes go, that did the trick! Again, I appreciate your assistance.

Extension manager tells that there is a grammar checking by default for the English spelling dictionaries, hyphenation rules, thesaurus and grammar checker (Marco A.G. Pinto).

I see that, but there’s absolutely nothing ticked in that extension’s options dialog.

@CraigG58 - my commented was referring to the statement:

Sorry for the confusion.

@anon73440385: I never succeeded in activating grammar check (it is not disabled in Writing Aids). I doubt that my English skill is so high that I never make a mistake. I have installed the extra language package for English variants (notably for en_UK I prefer over en_US) but I don’t get grammar check. What am I missing?

Installed packages (Fedora): autocorr-en hunspell-en hunspell-en-GB hunspell-en-US hyphen-en libreoffice-langpack-en mythes-en

Question 135537/how-to-enable-grammar-check-on-libre-writer/ references which does not seem to be a TDF site. It suggests to install Grammarly which is not a TDF extension.

I’d like a “pure” LO solution.


I’d like a “pure” LO solution.

that’s what I tried to express but did not elaborate my comment. What I wanted to say: I have a pure TDF LibreOffice rpm-package installation (currently on openSUSE 15.2, not using distro packages), and I have a fresh user profile (i.e. no changes, no extension installed and no modification to the profile) and I get the same observation as stated in the question. Then I read your answer, which I’d have fully agreed to one hour before, and then checked inspired by your answer, where grammar checking (in that special case) might come from. That’s all…

@CraigG58: please, tell me how many items you have in Tools>Options>Language Settings. I only have two: Languages and Writing Aids. If a grammar checker is installed (wherever it comes from), there should be a third item. Thanks in advance.

@ajlittoz: I have those two, plus one more called “English Sentence Checking”. Perhaps that’s due to the entire document being configured for “English (USA)”? At any rate, there are numerous tick boxes in there, but once again absolutely nothing is selected.

@CraigG58: considering what is said in the article, I suspect this comes from Grammarly. It may have been installed unbeknownst to you. What is your OS? What was your installation method?

@ajlittoz: Windows 10 64-bit… Did a straight install with the default options using the LibreOffice MSI file from:

@CraigG58: thanks, it looks like Windows packagers chose to include Grammarly extension without explicitly telling this. Linux distro packagers ship LO bare metal (without any extension).

@ajlittoz On my Windows PCs all include Lightproof grammar checker, listed in Writing Aids. It appears to be closely related to Hunspell. Interestingly, Lightproof site says available only for English US but mine all English UK.

Mint Linux installation does not have Lightproof Grammar checker which agrees with what you stated

@EarnestAl: I think that grammar-wise all en_xx are equal (or almost) in front of a grammar checker. The differences are more important morphologically (spelling) and maybe semantically, which should not really impact a grammar checker.

That’s true, I haven’t had any real disagreements with it. Happily, it is not aggressive in its suggestions
