How do German call their wife?

There's no single, universal term that Germans use to address their wives. Just like in English, the most common ways to address one's wife in German depend on the context and the level of formality:

Formal:

* Meine Frau (My wife) - This is the most formal and respectful way to refer to one's wife.

* Frau [last name] (Mrs. [last name]) - This is another formal way to address one's wife, especially in public or formal settings.

Informal:

* Meine Liebe (My love) - This is a common and affectionate way to address one's wife, often used in private settings.

* Schatz (Treasure) - This is another very common and affectionate term for one's wife.

* Liebling (Darling) - This is a sweet and loving term for one's wife.

* Mause (Mouse) - This is a cute and affectionate term for one's wife, often used playfully.

* Honey (Honey) - This term is becoming more common in German, especially among younger generations.

In addition to these common terms, many couples use nicknames or pet names specific to their relationship.

It's important to note that the choice of terms depends on the relationship between the speaker and the listener, as well as the context of the conversation.
