GERMANY; How do you say "Don't touch my wife!" in English.?

lass uns in Ruhe (leave us alone) is fine

forget the offensive extras like a**hole etc. that just inflames the situation.

intonation is important

lass oons in ROOOeh ! Shout that last word a littel and they will back off.

Germany is a civilized country - people will not TOUCH your wife! Where on earth are you from ....

Making threats to make people fear you is very very stupid - they might report you to the police for putting them into a state of fear and alarm, which is against the law in civilized countries. So don;'t do it. OH - and assuming your wife is able to speak - I'm sure that if someone bothers her, she will speak for herself, even if only to say " Please ignore my rude husband".

"Get the **** away from my wife!". Basic, Crude.

Be careful of trying this sort of thing though. Seemingly simple solutions can rapidly get out of control, possibly even violent. A better tactic is simply to guide your wife, literally, away from the place/situation.

The OP says "in english". The reason for "germany" (not "in german") is not detailed.

Don't touch my wife :

Fasse (touch) meine Frau nicht an (informal) Fassen Sie meine Frau nicht an (formal)

or:

Beleidige (offend, insult) meine Frau nicht (informal) Beleidigen Sie meine Frau nicht (formal)

or:

Lass meine Frau in Ruhe (leave my wife alone (informal) Lassen Sie meine Frau in Ruhe (formal)

''Fasst meine Frau nicht an!'' if you want them not to TOUCH her.

If you want them to back off or leave her alone, say ''Bleibt weg von meiner Ehefrau, ihr Nuttensöhne!'' or ''Lasst meine Frau verdammt noch mal in Ruhe, Arschlöcher!'' respectively.

You were talking about multiple people, right? Because you said ''some people'', not ''someone''.

Why ''Germany'', though?
