The Swedish Grammar Checker by Lingsoft, delivered as part of MS Office since
1999, is built using Constraint Grammar (CG1). Below are a couple of screen
shots illustrating how the grammar checker allerts and informs the user of
some common error types.

!!!Definitness error

The following sentence contains a definitness error:

And this is how the error is classified and reported to the user when right
clicked. The menu also contains a correction suggestion:

Note how the erroneous word itself (''slutsatsen'') is used in the feedback, as
well as the word that gives the syntactic context that triggers the error
(''Naturvårdsverkets''). Note also that the triggering word is __not__ the
immediately preceeding word.

If one selects the menu entry __Grammatikk...__ in the context menu, one is
presented with the following:

!!!Gender congruency error

The second error example is one where a modifier (''utökat'', a participle) of a
noun (''vargpopulation'') is not inflected for the gender of the noun:

Again, the context menu gives a lot of information about the error, using the
actual words in the sentence to refer to the error.

If one selects the __Grammatikk...__ option in the context menu, one gets the
following:

Ideally, we want to do something similar in our grammar checker, but limitations
in the host application and its grammar checker API may force us to do something
less advanced.

!!!Settings

The grammar checker comes with a number of premade settings, bundled together
in suitable style options (screen shots shown are from MS Office 2013):

If one clicks on the __Innstillinger…__ button, one can fine-tune the different
settings, or make one own's unique grammar checker style:

The Lingsoft grammar checker in Word has __41__ error categories that one can
turn on or off.
