Here's the breakdown of its etymology:
* German: "Sau" (pig)
* Yiddish: "hazer" (pig)
The Yiddish word "hazer" is a direct borrowing from the German word "Sau". This is typical of many Yiddish words, as the language developed alongside the Jewish communities in Germanic-speaking regions of Europe.
It's worth noting that the German word "Sau" itself has a broader meaning, encompassing both male and female pigs. In Yiddish, "hazer" is used for both genders, but the female pig is often referred to as "a zowe".
