I'm trying to fix some odd sentences in Dutch. I probably find some more, but I will start with the most strange one.

What I get now:
"Je kunt gaan Noord, Oost, Zuid"
(translation: You can go Nord, East, South.)

What I want is:
Je kunt Noord, Oost, Zuid gaan
(translation: You can Nord, East, South go.)

What I want is that the verb 'gaan/go' is at the end of te sentence.

Is the solution (in Nederlands.aslx) something like this:

<template name="GoListHeader">"Je kunt " + object.direction + " gaan."</template>

Can anyone help?

No, that is not possible. GoListHeader is used as a prefix, but there is no suffix for this. You would have to change the core function FormatExitList for this
