You might have a situation where you're sending travellers through a journey and the travellers might speak different languages. So you want them to see the form in a language they understand.
There are currently two ways to have forms in different languages:
1. If it's only two languages then you can just change the form so the questions will be in both languages, like this:
2. You can also just set the form up in one language and then duplicate it and change it to the new language. Then you can set up your Journey so it sends the correct form:
The branch on the right is then waiting for the form to either be filled out or skipped, so it will continue the branch on the right after the form has been filled out.
