Overwrite translations

Is it possible to overwrite translations?
For example, there is a translation of “Masters” in ERPNext to German “Stämme”.
I would like to overwrite that German translation to “Stammdaten”.

How can this be achieved?

There are a lot of wrong translations for Germany. A lot seems robotic translated. How can we support ERPnext to make the translations better?

I’m already verifier and look in there once a week or so.
