GE : grammar for anglicisms in German?

[Guest guest]

Dear colleagues

I have a gramar question.

The term „touchscreen“ which could be translated, I know (and I personally

do not like anglicisms in GE when they can be avoided, but this client has

his own opinion and prefers EN over „Berührungsbildschirm“ and the likes),

is used as „Touchscreen“ in German. Now my question is, when it comes to the

genitiv (?) case: „des Touchscreen“ would you add an „s“ (des Touchscreens…)

or not? I am not sure about the oficial rules for such words (I feel like it

should be added but of course „feeling“ is not appropriate as a decision

helper here).

Can anyone help?

Thank you very much
