With the ascii apostrophe ', the spell checker defaults to treating words with a genetive s as bad; can that be remedied?

    I don't see this problem with 'spelllang' set to en, unless it is clearly wrong, e.g.: dog's is displayed without any mark, while the's is marked as an error. Can you please provide a example and the value of 'spelllang' you are using?

  • @mMontu, Sorry, I see now that it is only a problem with some words. Examples: potential's, something's.

The words potential's and something's are not in the default spell file.

I checked this by enabling spell checking, and then using the :spelldump command. This will create a new buffer with all valid words.

If you do :g/'s$/ you will see that words ending with 's are separate entries.

So your solution is to add these words to the spell file. This can be done easily with either zg from normal mode, or the :spellgood command.

    I was hoping for something less cumbersome. Would it not be possible to make the spell checker treat the apostrophe as a word boundary? Even if there should be any word that could not be put into the genetive, I don't see much danger of doing it by mistype.

    @Lawrence Not easily as far as I can see. See the "WORDS" section in :help spell. You can probably hack the binary .spl file, but adding a few words to a spellfile is probably easier... Commented Feb 24, 2016 at 14:35
